Neither were there any restrictions against moderate drinking or eating sweets. Other tools more specific to cooking over an open fire were spits of various sizes, and material for skewering anything from delicate quails to whole oxen. Shared drinking cups were common even at lavish banquets for all but those who sat at the high table , as was the standard etiquette of breaking bread and carving meat for one's fellow diners. I signed up for Nutrisystem this week, and I am really hoping that I have the same results. Smoking or salting meat of livestock butchered in autumn was a common household strategy to avoid having to feed more animals than necessary during the lean winter months. Fruit was popular and could be served fresh, dried, or preserved, and was a common ingredient in many cooked dishes.

One's lifestyle—including diet, exercise, appropriate social behavior, and approved medical remedies—was the way to good health, and all types of food were assigned certain properties that affected a person's health. All foodstuffs were also classified on scales ranging from hot to cold and moist to dry, according to the four bodily humours theory proposed by Galen that dominated Western medical science from late Antiquity until the 17th century.

Medieval scholars considered human digestion to be a process similar to cooking. The processing of food in the stomach was seen as a continuation of the preparation initiated by the cook. In order for the food to be properly "cooked" and for the nutrients to be properly absorbed, it was important that the stomach be filled in an appropriate manner.

Easily digestible foods would be consumed first, followed by gradually heavier dishes. If this regimen were not respected it was believed that heavy foods would sink to the bottom of the stomach, thus blocking the digestion duct, so that food would digest very slowly and cause putrefaction of the body and draw bad humours into the stomach.

It was also of vital importance that food of differing properties not be mixed. Before a meal, the stomach would preferably be "opened" with an apéritif from Latin aperire , "to open" that was preferably of a hot and dry nature: As the stomach had been opened, it should then be "closed" at the end of the meal with the help of a digestive, most commonly a dragée , which during the Middle Ages consisted of lumps of spiced sugar, or hypocras , a wine flavoured with fragrant spices, along with aged cheese.

A meal would ideally begin with easily digestible fruit, such as apples. It would then be followed by vegetables such as lettuce , cabbage , purslane , herbs, moist fruits, light meats, such as chicken or goat kid , with potages and broths. After that came the "heavy" meats, such as pork and beef , as well as vegetables and nuts, including pears and chestnuts, both considered difficult to digest. It was popular, and recommended by medical expertise, to finish the meal with aged cheese and various digestives.

The most ideal food was that which most closely matched the humour of human beings, i. Food should preferably also be finely chopped, ground, pounded and strained to achieve a true mixture of all the ingredients. White wine was believed to be cooler than red and the same distinction was applied to red and white vinegar. Milk was moderately warm and moist, but the milk of different animals was often believed to differ.

Egg yolks were considered to be warm and moist while the whites were cold and moist. Skilled cooks were expected to conform to the regimen of humoral medicine. Even if this limited the combinations of food they could prepare, there was still ample room for artistic variation by the chef. The caloric content and structure of medieval diet varied over time, from region to region, and between classes. However, for most people, the diet tended to be high-carbohydrate, with most of the budget spent on, and the majority of calories provided by, cereals and alcohol such as beer.

Even though meat was highly valued by all, lower classes often could not afford it, nor were they allowed by the church to consume it every day. In one early 15th-century English aristocratic household for which detailed records are available that of the Earl of Warwick , gentle members of the household received a staggering 3.

In the household of Henry Stafford in , gentle members received 2. In monasteries, the basic structure of the diet was laid down by the Rule of Saint Benedict in the 7th century and tightened by Pope Benedict XII in , but as mentioned above monks were adept at "working around" these rules. This was circumvented in part by declaring that offal , and various processed foods such as bacon , were not meat.

Secondly, Benedictine monasteries contained a room called the misericord , where the Rule of Saint Benedict did not apply, and where a large number of monks ate. Each monk would be regularly sent either to the misericord or to the refectory. When Pope Benedict XII ruled that at least half of all monks should be required to eat in the refectory on any given day, monks responded by excluding the sick and those invited to the abbot's table from the reckoning. The overall caloric intake is subject to some debate.

As a consequence of these excesses, obesity was common among upper classes. The regional specialties that are a feature of early modern and contemporary cuisine were not in evidence in the sparser documentation that survives. Instead, medieval cuisine can be differentiated by the cereals and the oils that shaped dietary norms and crossed ethnic and, later, national boundaries.

Geographical variation in eating was primarily the result of differences in climate, political administration, and local customs that varied across the continent. Though sweeping generalizations should be avoided, more or less distinct areas where certain foodstuffs dominated can be discerned. In the British Isles , northern France , the Low Countries , the northern German-speaking areas, Scandinavia and the Baltic , the climate was generally too harsh for the cultivation of grapes and olives.

In the south, wine was the common drink for both rich and poor alike though the commoner usually had to settle for cheap second pressing wine while beer was the commoner's drink in the north and wine an expensive import. Citrus fruits though not the kinds most common today and pomegranates were common around the Mediterranean.

Dried figs and dates were available in the north, but were used rather sparingly in cooking. Olive oil was a ubiquitous ingredient in Mediterranean cultures, but remained an expensive import in the north where oils of poppy , walnut, hazel and filbert were the most affordable alternatives. Butter and lard , especially after the terrible mortality during the Black Death made them less scarce, were used in considerable quantities in the northern and northwestern regions, especially in the Low Countries.

Almost universal in middle and upper class cooking all over Europe was the almond , which was in the ubiquitous and highly versatile almond milk , which was used as a substitute in dishes that otherwise required eggs or milk, though the bitter variety of almonds came along much later. In Europe there were typically two meals a day: The two-meal system remained consistent throughout the late Middle Ages. Smaller intermediate meals were common, but became a matter of social status, as those who did not have to perform manual labor could go without them.

For practical reasons, breakfast was still eaten by working men, and was tolerated for young children, women, the elderly and the sick. Because the church preached against gluttony and other weaknesses of the flesh, men tended to be ashamed of the weak practicality of breakfast.

Lavish dinner banquets and late-night reresopers from Occitan rèire-sopar , "late supper" with considerable amounts of alcoholic beverage were considered immoral. The latter were especially associated with gambling, crude language, drunkenness, and lewd behavior.

As with almost every part of life at the time, a medieval meal was generally a communal affair. The entire household, including servants, would ideally dine together. To sneak off to enjoy private company was considered a haughty and inefficient egotism in a world where people depended very much on each other.

When possible, rich hosts retired with their consorts to private chambers where the meal could be enjoyed in greater exclusivity and privacy. Being invited to a lord's chambers was a great privilege and could be used as a way to reward friends and allies and to awe subordinates.

It allowed lords to distance themselves further from the household and to enjoy more luxurious treats while serving inferior food to the rest of the household that still dined in the great hall. At major occasions and banquets, however, the host and hostess generally dined in the great hall with the other diners. However, it can be assumed there were no such extravagant luxuries as multiple courses , luxurious spices or hand-washing in scented water in everyday meals.

Things were different for the wealthy. Before the meal and between courses, shallow basins and linen towels were offered to guests so they could wash their hands, as cleanliness was emphasized. Social codes made it difficult for women to uphold the ideal of immaculate neatness and delicacy while enjoying a meal, so the wife of the host often dined in private with her entourage or ate very little at such feasts.

She could then join dinner only after the potentially messy business of eating was done. Overall, fine dining was a predominantly male affair, and it was uncommon for anyone but the most honored of guests to bring his wife or her ladies-in-waiting. The hierarchical nature of society was reinforced by etiquette where the lower ranked were expected to help the higher, the younger to assist the elder, and men to spare women the risk of sullying dress and reputation by having to handle food in an unwomanly fashion.

Shared drinking cups were common even at lavish banquets for all but those who sat at the high table , as was the standard etiquette of breaking bread and carving meat for one's fellow diners.

Food was mostly served on plates or in stew pots, and diners would take their share from the dishes and place it on trenchers of stale bread, wood or pewter with the help of spoons or bare hands.

In lower-class households it was common to eat food straight off the table. Knives were used at the table, but most people were expected to bring their own, and only highly favored guests would be given a personal knife. A knife was usually shared with at least one other dinner guest, unless one was of very high rank or well-acquainted with the host.

Forks for eating were not in widespread usage in Europe until the early modern period , and early on were limited to Italy. Even there it was not until the 14th century that the fork became common among Italians of all social classes. The change in attitudes can be illustrated by the reactions to the table manners of the Byzantine princess Theodora Doukaina in the late 11th century.

She was the wife of Domenico Selvo , the Doge of Venice , and caused considerable dismay among upstanding Venetians. The foreign consort's insistence on having her food cut up by her eunuch servants and then eating the pieces with a golden fork shocked and upset the diners so much that there was a claim that Peter Damian , Cardinal Bishop of Ostia , later interpreted her refined foreign manners as pride and referred to her as " All types of cooking involved the direct use of fire.

Kitchen stoves did not appear until the 18th century, and cooks had to know how to cook directly over an open fire. Ovens were used, but they were expensive to construct and only existed in fairly large households and bakeries.

It was common for a community to have shared ownership of an oven to ensure that the bread baking essential to everyone was made communal rather than private. There were also portable ovens designed to be filled with food and then buried in hot coals, and even larger ones on wheels that were used to sell pies in the streets of medieval towns.

But for most people, almost all cooking was done in simple stewpots, since this was the most efficient use of firewood and did not waste precious cooking juices, making potages and stews the most common dishes.

This was considered less of a problem in a time of back-breaking toil, famine, and a greater acceptance—even desirability—of plumpness; only the poor or sick, and devout ascetics , were thin. Fruit was readily combined with meat, fish and eggs. The recipe for Tart de brymlent , a fish pie from the recipe collection Forme of Cury , includes a mix of figs , raisins , apples and pears with fish salmon , codling or haddock and pitted damson plums under the top crust.

This meant that food had to be "tempered" according to its nature by an appropriate combination of preparation and mixing certain ingredients, condiments and spices; fish was seen as being cold and moist, and best cooked in a way that heated and dried it, such as frying or oven baking, and seasoned with hot and dry spices; beef was dry and hot and should therefore be boiled ; pork was hot and moist and should therefore always be roasted.

In a recipe for quince pie, cabbage is said to work equally well, and in another turnips could be replaced by pears. The completely edible shortcrust pie did not appear in recipes until the 15th century. Before that the pastry was primarily used as a cooking container in a technique known as ' huff paste '. Extant recipe collections show that gastronomy in the Late Middle Ages developed significantly.

New techniques, like the shortcrust pie and the clarification of jelly with egg whites began to appear in recipes in the late 14th century and recipes began to include detailed instructions instead of being mere memory aids to an already skilled cook. In most households, cooking was done on an open hearth in the middle of the main living area, to make efficient use of the heat.

This was the most common arrangement, even in wealthy households, for most of the Middle Ages, where the kitchen was combined with the dining hall. Towards the Late Middle Ages a separate kitchen area began to evolve.

The first step was to move the fireplaces towards the walls of the main hall, and later to build a separate building or wing that contained a dedicated kitchen area, often separated from the main building by a covered arcade.

This way, the smoke, odors and bustle of the kitchen could be kept out of sight of guests, and the fire risk lessened. Many basic variations of cooking utensils available today, such as frying pans , pots , kettles , and waffle irons , already existed, although they were often too expensive for poorer households. Other tools more specific to cooking over an open fire were spits of various sizes, and material for skewering anything from delicate quails to whole oxen.

Utensils were often held directly over the fire or placed into embers on tripods. To assist the cook there were also assorted knives, stirring spoons, ladles and graters.

In wealthy households one of the most common tools was the mortar and sieve cloth, since many medieval recipes called for food to be finely chopped, mashed, strained and seasoned either before or after cooking. This was based on a belief among physicians that the finer the consistency of food, the more effectively the body would absorb the nourishment. It also gave skilled cooks the opportunity to elaborately shape the results.

Fine-textured food was also associated with wealth; for example, finely milled flour was expensive, while the bread of commoners was typically brown and coarse. A typical procedure was farcing from the Latin farcio , "to cram" , to skin and dress an animal, grind up the meat and mix it with spices and other ingredients and then return it into its own skin, or mold it into the shape of a completely different animal. The kitchen staff of huge noble or royal courts occasionally numbered in the hundreds: While an average peasant household often made do with firewood collected from the surrounding woodlands, the major kitchens of households had to cope with the logistics of daily providing at least two meals for several hundred people.

Guidelines on how to prepare for a two-day banquet can be found in the cookbook Du fait de cuisine "On cookery" written in in part to compete with the court of Burgundy [44] by Maistre Chiquart, master chef of Amadeus VIII, Duke of Savoy.

Food preservation methods were basically the same as had been used since antiquity, and did not change much until the invention of canning in the early 19th century. The most common and simplest method was to expose foodstuffs to heat or wind to remove moisture , thereby prolonging the durability if not the flavor of almost any type of food from cereals to meats; the drying of food worked by drastically reducing the activity of various water-dependent microorganisms that cause decay.

In warm climates this was mostly achieved by leaving food out in the sun, and in the cooler northern climates by exposure to strong winds especially common for the preparation of stockfish , or in warm ovens, cellars, attics, and at times even in living quarters. Subjecting food to a number of chemical processes such as smoking , salting , brining , conserving or fermenting also made it keep longer.

Most of these methods had the advantage of shorter preparation times and of introducing new flavors. Smoking or salting meat of livestock butchered in autumn was a common household strategy to avoid having to feed more animals than necessary during the lean winter months.

Vegetables, eggs or fish were also often pickled in tightly packed jars, containing brine and acidic liquids lemon juice , verjuice or vinegar. Another method was to seal the food by cooking it in sugar or honey or fat, in which it was then stored. Microbial modification was also encouraged, however, by a number of methods; grains, fruit and grapes were turned into alcoholic drinks thus killing any pathogens, and milk was fermented and curdled into a multitude of cheeses or buttermilk.

The majority of the European population before industrialization lived in rural communities or isolated farms and households. The norm was self-sufficiency with only a small percentage of production being exported or sold in markets. Large towns were exceptions and required their surrounding hinterlands to support them with food and fuel. The dense urban population could support a wide variety of food establishments that catered to various social groups.

Many of the poor city dwellers had to live in cramped conditions without access to a kitchen or even a hearth, and many did not own the equipment for basic cooking.

Food from vendors was in such cases the only option. Cookshops could either sell ready-made hot food, an early form of fast food , or offer cooking services while the customers supplied some or all of the ingredients. Travellers, such as pilgrims en route to a holy site, made use of professional cooks to avoid having to carry their provisions with them.

For the more affluent, there were many types of specialist that could supply various foods and condiments: Well-off citizens who had the means to cook at home could on special occasions hire professionals when their own kitchen or staff could not handle the burden of throwing a major banquet.

Urban cookshops that catered to workers or the destitute were regarded as unsavory and disreputable places by the well-to-do and professional cooks tended to have a bad reputation. Geoffrey Chaucer 's Hodge of Ware, the London cook from the Canterbury Tales , is described as a sleazy purveyor of unpalatable food.

French cardinal Jacques de Vitry 's sermons from the early 13th century describe sellers of cooked meat as an outright health hazard. The stereotypical cook in art and literature was male, hot-tempered, prone to drunkenness, and often depicted guarding his stewpot from being pilfered by both humans and animals. In the early 15th century, the English monk John Lydgate articulated the beliefs of many of his contemporaries by proclaiming that "Hoot ffir [fire] and smoke makith many an angry cook.

The period between c. More intense agriculture on an ever-increasing acreage resulted in a shift from animal products, like meat and dairy, to various grains and vegetables as the staple of the majority population.

A bread-based diet became gradually more common during the 15th century and replaced warm intermediate meals that were porridge- or gruel-based. Leavened bread was more common in wheat-growing regions in the south, while unleavened flatbread of barley, rye or oats remained more common in northern and highland regions, and unleavened flatbread was also common as provisions for troops.

The most common grains were rye , barley , buckwheat , millet and oats. Rice remained a fairly expensive import for most of the Middle Ages and was grown in northern Italy only towards the end of the period.

Wheat was common all over Europe and was considered to be the most nutritious of all grains, but was more prestigious and thus more expensive. The finely sifted white flour that modern Europeans are most familiar with was reserved for the bread of the upper classes. As one descended the social ladder, bread became coarser, darker, and its bran content increased.

In times of grain shortages or outright famine, grains could be supplemented with cheaper and less desirable substitutes like chestnuts , dried legumes , acorns , ferns , and a wide variety of more or less nutritious vegetable matter.

One of the most common constituents of a medieval meal, either as part of a banquet or as a small snack, were sops , pieces of bread with which a liquid like wine , soup , broth , or sauce could be soaked up and eaten.

Another common sight at the medieval dinner table was the frumenty , a thick wheat porridge often boiled in a meat broth and seasoned with spices. Porridges were also made of every type of grain and could be served as desserts or dishes for the sick, if boiled in milk or almond milk and sweetened with sugar. Pies filled with meats, eggs, vegetables, or fruit were common throughout Europe, as were turnovers , fritters , doughnuts , and many similar pastries. By the Late Middle Ages biscuits cookies in the U.

Grain, either as bread crumbs or flour, was also the most common thickener of soups and stews, alone or in combination with almond milk. The importance of bread as a daily staple meant that bakers played a crucial role in any medieval community. Bread consumption was high in most of Western Europe by the 14th century.

Estimates of bread consumption from different regions are fairly similar: Among the first town guilds to be organized were the bakers', and laws and regulations were passed to keep bread prices stable. The English Assize of Bread and Ale of listed extensive tables where the size, weight, and price of a loaf of bread were regulated in relation to grain prices.

The baker's profit margin stipulated in the tables was later increased through successful lobbying from the London Baker's Company by adding the cost of everything from firewood and salt to the baker's wife, house, and dog.

Since bread was such a central part of the medieval diet, swindling by those who were trusted with supplying the precious commodity to the community was considered a serious offense. Bakers who were caught tampering with weights or adulterating dough with less expensive ingredients could receive severe penalties. This gave rise to the " baker's dozen ": While grains were the primary constituent of most meals, vegetables such as cabbage , chard , onions , garlic and carrots were common foodstuffs.

Many of these were eaten daily by peasants and workers and were less prestigious than meat. The cookbooks, which appeared in the late Middle Ages and were intended mostly for those who could afford such luxuries, contained only a small number of recipes using vegetables as the main ingredient.

The lack of recipes for many basic vegetable dishes, such as potages , has been interpreted not to mean that they were absent from the meals of the nobility, but rather that they were considered so basic that they did not require recording. Various legumes , like chickpeas , fava beans and field peas were also common and important sources of protein , especially among the lower classes.

With the exception of peas, legumes were often viewed with some suspicion by the dietitians advising the upper class, partly because of their tendency to cause flatulence but also because they were associated with the coarse food of peasants. The importance of vegetables to the common people is illustrated by accounts from 16th-century Germany stating that many peasants ate sauerkraut from three to four times a day.

Fruit was popular and could be served fresh, dried, or preserved, and was a common ingredient in many cooked dishes. The fruits of choice in the south were lemons , citrons , bitter oranges the sweet type was not introduced until several hundred years later , pomegranates , quinces , and, of course, grapes.

Farther north, apples , pears , plums , and strawberries were more common. Figs and dates were eaten all over Europe, but remained rather expensive imports in the north. Common and often basic ingredients in many modern European cuisines like potatoes , kidney beans , cacao , vanilla , tomatoes , chili peppers and maize were not available to Europeans until after , after European contact with the Americas, and even then it often took considerable time, sometimes several centuries, for the new foodstuffs to be accepted by society at large.

Milk was an important source of animal protein for those who could not afford meat. It would mostly come from cows, but milk from goats and sheep was also common. Plain fresh milk was not consumed by adults except the poor or sick, and was usually reserved for the very young or elderly. Poor adults would sometimes drink buttermilk or whey or milk that was soured or watered down. On occasion it was used in upper-class kitchens in stews, but it was difficult to keep fresh in bulk and almond milk was generally used in its stead.

Cheese was far more important as a foodstuff, especially for common people, and it has been suggested that it was, during many periods, the chief supplier of animal protein among the lower classes. There were also whey cheeses , like ricotta , made from by-products of the production of harder cheeses. Cheese was used in cooking for pies and soups, the latter being common fare in German-speaking areas.

Butter , another important dairy product, was in popular use in the regions of Northern Europe that specialized in cattle production in the latter half of the Middle Ages, the Low Countries and Southern Scandinavia. While most other regions used oil or lard as cooking fats, butter was the dominant cooking medium in these areas.

Its production also allowed for a lucrative butter export from the 12th century onward. While all forms of wild game were popular among those who could obtain it, most meat came from domestic animals. Domestic working animals that were no longer able to work were slaughtered but not particularly appetizing and therefore were less valued as meat.

Beef was not as common as today because raising cattle was labor-intensive, requiring pastures and feed, and oxen and cows were much more valuable as draught animals and for producing milk. Mutton and lamb were fairly common, especially in areas with a sizeable wool industry, as was veal.

Domestic pigs often ran freely even in towns and could be fed on just about any organic waste, and suckling pig was a sought-after delicacy. Just about every part of the pig was eaten, including ears, snout, tail, tongue , and womb. Intestines, bladder and stomach could be used as casings for sausage or even illusion food such as giant eggs.

Among the meats that today are rare or even considered inappropriate for human consumption are the hedgehog and porcupine , occasionally mentioned in late medieval recipe collections. In England, they were deliberately introduced by the 13th century and their colonies were carefully protected. They were of particular value for monasteries, because newborn rabbits were allegedly declared fish or, at least, not-meat by the church and therefore they could be eaten during Lent.

A wide range of birds were eaten, including swans , peafowl , quail , partridge , storks , cranes , larks , linnets and other songbirds that could be trapped in nets, and just about any other wild bird that could be hunted. Swans and peafowl were domesticated to some extent, but were only eaten by the social elite, and more praised for their fine appearance as stunning entertainment dishes, entremets , than for their meat.

As today, geese and ducks had been domesticated but were not as popular as the chicken , the fowl equivalent of the pig. But at the Fourth Council of the Lateran , Pope Innocent III explicitly prohibited the eating of barnacle geese during Lent, arguing that they lived and fed like ducks and so were of the same nature as other birds.

Meats were more expensive than plant foods. Though rich in protein , the calorie -to-weight ratio of meat was less than that of plant food. Meat could be up to four times as expensive as bread.

Fish was up to 16 times as costly, and was expensive even for coastal populations. This meant that fasts could mean an especially meager diet for those who could not afford alternatives to meat and animal products like milk and eggs. It was only after the Black Death had eradicated up to half of the European population that meat became more common even for poorer people. The drastic reduction in many populated areas resulted in a labor shortage, meaning that wages dramatically increased.

It also left vast areas of farmland untended, making them available for pasture and putting more meat on the market. Although less prestigious than other animal meats, and often seen as merely an alternative to meat on fast days, seafood was the mainstay of many coastal populations.

Also included were the beaver , due to its scaly tail and considerable time spent in water, and barnacle geese , due to the belief that they developed underwater in the form of barnacles. The Holy Roman Emperor Frederick II examined barnacles and noted no evidence of any bird-like embryo in them, and the secretary of Leo of Rozmital wrote a very skeptical account of his reaction to being served barnacle goose at a fish-day dinner in Especially important was the fishing and trade in herring and cod in the Atlantic and the Baltic Sea.

The herring was of unprecedented significance to the economy of much of Northern Europe, and it was one of the most common commodities traded by the Hanseatic League , a powerful north German alliance of trading guilds. Kippers made from herring caught in the North Sea could be found in markets as far away as Constantinople.

Stockfish , cod that was split down the middle, fixed to a pole and dried, was very common, though preparation could be time-consuming, and meant beating the dried fish with a mallet before soaking it in water.

A wide range of mollusks including oysters , mussels and scallops were eaten by coastal and river-dwelling populations, and freshwater crayfish were seen as a desirable alternative to meat during fish days. Compared to meat, fish was much more expensive for inland populations, especially in Central Europe, and therefore not an option for most. Freshwater fish such as pike , carp , bream , perch , lamprey and trout were common.

While in modern times, water is often drunk with a meal, in the Middle Ages, however, concerns over purity, medical recommendations and its low prestige value made it less favored, and alcoholic beverages were preferred. They were seen as more nutritious and beneficial to digestion than water, with the invaluable bonus of being less prone to putrefaction due to the alcohol content. Wine was consumed on a daily basis in most of France and all over the Western Mediterranean wherever grapes were cultivated.

Further north it remained the preferred drink of the bourgeoisie and the nobility who could afford it, and far less common among peasants and workers. The drink of commoners in the northern parts of the continent was primarily beer or ale.

Juices , as well as wines, of a multitude of fruits and berries had been known at least since Roman antiquity and were still consumed in the Middle Ages: Since the amount and quality of leptin receptors in the hypothalamus appears to be normal in the majority of obese humans as judged from leptin-mRNA studies , [] it is likely that the leptin resistance in these individuals is due to a post leptin-receptor deficit, similar to the post-insulin receptor defect seen in type 2 diabetes.

When leptin binds with the leptin receptor, it activates a number of pathways. Mice with a mutation in the leptin receptor gene that prevents the activation of STAT3 are obese and exhibit hyperphagia. The PI3K pathway may also be involved in leptin resistance, as has been demonstrated in mice by artificial blocking of PI3K signalling.

The PI3K pathway also is activated by the insulin receptor and is therefore an important area where leptin and insulin act together as part of energy homeostasis. The consumption of a high fructose diet from birth has been associated with a reduction in leptin levels and reduced expression of leptin receptor mRNA in rats.

Long-term consumption of fructose in rats has been shown to increase levels of triglycerides and trigger leptin and insulin resistance, [] [] however, another study found that leptin resistance only developed in the presence of both high fructose and high fat levels in the diet.

A third study found that high fructose levels reversed leptin resistance in rats given a high fat diet. The contradictory results mean that it is uncertain whether leptin resistance is caused by high levels of carbohydrates or fats, or if an increase of both, is needed.

Leptin is known to interact with amylin , a hormone involved in gastric emptying and creating a feeling of fullness.

When both leptin and amylin were given to obese, leptin-resistant rats, sustained weight loss was seen. Due to its apparent ability to reverse leptin resistance, amylin has been suggested as possible therapy for obesity. It has been suggested that the main role of leptin is to act as a starvation signal when levels are low, to help maintain fat stores for survival during times of starvation, rather than a satiety signal to prevent overeating. Leptin levels signal when an animal has enough stored energy to spend it in pursuits besides acquiring food.

Dieters who lose weight, particularly those with an overabundance of fat cells, experience a drop in levels of circulating leptin. This drop causes reversible decreases in thyroid activity, sympathetic tone, and energy expenditure in skeletal muscle, and increases in muscle efficiency and parasympathetic tone. A decline in levels of circulating leptin also changes brain activity in areas involved in the regulatory, emotional, and cognitive control of appetite that are reversed by administration of leptin.

Osteoarthritis and obesity are closely linked. Obesity is one of the most important preventable factors for the development of osteoarthritis. Originally, the relationship between osteoarthritis and obesity was considered to be exclusively biomechanically based, according to which the excess weight caused the joint to become worn down more quickly.

However, today we recognise that there is also a metabolic component which explains why obesity is a risk factor for osteoarthritis, not only for weight-bearing joints for example, the knees , but also for joints that do not bear weight for example, the hands. Thus, the deregulated production of adipokines and inflammatory mediators, hyperlipidaemia, and the increase of systemic oxidative stress are conditions frequently associated with obesity which can favour joint degeneration.

Furthermore, many regulation factors have been implicated in the development, maintenance and function, both of adipose tissues, as well as of the cartilage and other joint tissues. Alterations in these factors can be the additional link between obesity and osteoarthritis.

Adipocytes interact with other cells through producing and secreting a variety of signalling molecules, including the cell signalling proteins known as adipokines.

Certain adipokines can be considered as hormones, as they regulate the functions of organs at a distance, and several of them have been specifically involved in the physiopathology of joint diseases. In particular, there is one, leptin, which has been the focus of attention for research in recent years. The circulating leptin levels are positively correlated with the Body Mass Index BMI , more specifically with fatty mass, and obese individuals have higher leptin levels in their blood circulation, compared with non-obese individuals.

In addition to the function of regulating energy homeostasis, leptin carries out a role in other physiological functions such as neuroendocrine communication, reproduction, angiogenesis and bone formation. More recently, leptin has been recognised as a cytokine factor as well as with pleiotropic actions also in the immune response and inflammation. Leptin has thus emerged as a candidate to link obesity and osteoarthritis and serves as an apparent objective as a nutritional treatment for osteoarthritis.

As in the plasma, the leptin levels in the synovial fluid are positively correlated with BMI. Leptin has been shown to be produced by chondrocytes, as well as by other tissues in the joints, including the synovial tissue, osteophytes, the meniscus and bone. The risk of suffering osteoarthritis can be decreased with weight loss.

This reduction of risk is related in part with the decrease of the load on the joint, but also in the decrease of fatty mass, the central adipose tissue and the low-level inflammation associated with obesity and systemic factors. This growing evidence points to leptin as a cartilage degradation factor in the pathogenesis of osteoarthritis, and as a potential biomarker in the progression of the disease, which suggests that leptin, as well as regulation and signalling mechanisms, can be a new and promising target in the treatment of osteoarthritis, especially in obese patients.

Obese individuals are predisposed to developing osteoarthritis, not only due to the excess mechanical load, but also due to the excess expression of soluble factors, that is, leptin and pro-inflammatory cytokines, which contribute to joint inflammation and cartilage destruction.

As such, obese individuals are in an altered state, due to a metabolic insufficiency, which requires specific nutritional treatment capable of normalising the leptin production and reducing the systematic low-level inflammation, in order to reduce the harmful impact of these systematic mediators on the joint health. There are nutritional supplements and pharmacological agents capable of directing these factors and improving both conditions.

Leptin was approved in the United States in for use in congenital leptin deficiency and generalized lipodystrophy. An analog of human leptin metreleptin trade name Myalept was first approved in Japan in , and in the United States in February In the US it is indicated as a treatment for complications of leptin deficiency, and for the diabetes and hypertriglyceridemia associated with congenital or acquired generalized lipodystrophy.
