Protein-sparing Modified Fast
A protein-sparing modified fast or PSMF diet is a type of a very-low-calorie diet (<800 kcal per day) with a high proportion of protein calories and simultaneous restriction of carbohydrate and fat. It includes a component, , and vitamin and mineral supplementation. PSMF diets can last for up to 6 months, followed by a gradual increase in calories over 6–8 weeks. Description A PSMF attempts to spare the dieter the health risks of a complete fast by introducing the minimum amount of protein necessary to prevent muscle-wasting effects, while still ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Very-low-calorie Diet
A very-low-calorie diet (VLCD), also known as semistarvation diet and crash diet, is a type of diet with very or extremely low daily food energy consumption. Often described as a fad diet, it is defined as a diet of per day or less. Modern medically supervised VLCDs use total meal replacements, with regulated formulations in Europe and Canada which contain the recommended daily requirements for vitamins, minerals, trace elements, fatty acids, protein and electrolyte balance. Carbohydrates may be entirely absent, or substituted for a portion of the protein; this choice has important metabolic effects. Medically supervised VLCDs have specific therapeutic applications for rapid weight loss, such as in morbid obesity or before a bariatric surgery, using formulated, nutritionally complete liquid meals containing 800 kilocalories or less per day for a maximum of 12 weeks. Unmonitored VLCDs with insufficient or unbalanced nutrients can cause sudden death by cardiac arrest either by s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fasting
Fasting is the abstention from eating and sometimes drinking. From a purely physiological context, "fasting" may refer to the metabolic status of a person who has not eaten overnight (see " Breakfast"), or to the metabolic state achieved after complete digestion and absorption of a meal. Metabolic changes in the fasting state begin after absorption of a meal (typically 3–5 hours after eating). A diagnostic fast refers to prolonged fasting from 1 to 100 hours (depending on age) conducted under observation to facilitate the investigation of a health complication, usually hypoglycemia. Many people may also fast as part of a medical procedure or a check-up, such as preceding a colonoscopy or surgery, or before certain medical tests. Intermittent fasting is a technique sometimes used for weight loss that incorporates regular fasting into a person's dietary schedule. Fasting may also be part of a religious ritual, often associated with specifically scheduled fast days, as de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Régime Protal
In politics, a regime (also "régime") is the form of government or the set of rules, cultural or social norms, etc. that regulate the operation of a government or institution and its interactions with society. According to Yale professor Juan José Linz there a three main types of political regimes today: democracies, totalitarian regimes and, sitting between these two, authoritarian regimes (with hybrid regimes). Usage While the word ''régime'' originates as a synonym for any type of government, modern usage has given it a negative connotation, implying an authoritarian government or dictatorship. Webster's definition states that the word ''régime'' refers simply to a form of government, while Oxford English Dictionary defines ''regime'' as "a government, especially an authoritarian one". Contemporary academic usage of the term "regime" is broader than popular and journalistic usage, meaning "an intermediate stratum between the government (which makes day-to-day decisio ...

Fad Diets
A fad diet is a diet that becomes popular for a short time, similar to fads in fashion, without being a standard dietary recommendation, and often making unreasonable claims for fast weight loss or health improvements. There is no single definition of what is a fad diet. The term fad diet encompasses a variety of diets with different approaches and evidence bases, and thus different outcomes, advantages, and disadvantages. Generally, fad diets promise an assortment of short-term changes requiring little to no effort; attracting the interests of uneducated consumers about whole-diet, whole-lifestyle changes necessary for sustainable health benefices. Fad diets are often promoted with exaggerated claims, such as rapid weight loss of more than 1 kg/week, improving health by "detoxification", or even dangerous claims, such as highly restrictive and nutritionally unbalanced food choices leading to malnutrition or eating non-food items like cotton wool. Highly restrictive fad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proteins As Nutrients
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Diets
The Low Countries comprise the coastal Rhine–Meuse–Scheldt delta region in Western Europe, whose definition usually includes the modern countries of Luxembourg, Belgium and the Netherlands. Both Belgium and the Netherlands derived their names from earlier names for the region, due to ''nether'' meaning "low" and ''Belgica'' being the Latinized name for all the Low Countries, a nomenclature that became obsolete after Belgium's secession in 1830. The Low Countries—and the Netherlands and Belgium—had in their history exceptionally many and widely varying names, resulting in equally varying names in different languages. There is diversity even within languages: the use of one word for the country and another for the adjective form is common. This holds for English, where ''Dutch'' is the adjective form for the country "the Netherlands". Moreover, many languages have the same word for both the country of the Netherlands and the region of the Low Countries, e.g., French ( ...

Stillman Diet
The Stillman Diet is a high-protein, low-carbohydrate diet that was created in 1967 by physician Irwin Maxwell Stillman (1896–1975). Overview Stillman and Samm Sinclair Baker authored the book ''The Doctor's Quick Weight Loss Diet'' that first advertised the Stillman Diet in 1967. The animal based high-protein diet includes lean beef, veal, chicken, turkey, fish, eggs and non-fat cottage cheese. Spices, tabasco sauce, herbs, salt, and pepper are also allowed. Condiments, butter, dressings and any kind of fat or oil are not permitted. Tea, coffee, and non-caloric soft drinks can be consumed, but only in addition to the 8 daily glasses of water required. It's also recommended that dieters eat 6 small meals per day instead of 3 large ones. The diet is a carbohydrate-restricted diet, similar to that of Dr. Robert Atkins', Atkins Diet (although Atkins' diet allows significant fat consumption). Karen Carpenter Karen Carpenter began using the diet in her teens. Karen was 5'4" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-carbohydrate Diet
Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet. Foods high in carbohydrates (e.g., sugar, bread, pasta) are limited, and replaced with foods containing a higher percentage of fat and protein (e.g., meat, poultry, fish, shellfish, eggs, cheese, nuts, and seeds), as well as low carbohydrate foods (e.g. spinach, kale, chard, collards, and other fibrous vegetables). There is a lack of standardization of how much carbohydrate low-carbohydrate diets must have, and this has complicated research. One definition, from the American Academy of Family Physicians, specifies low-carbohydrate diets as having less than 20% of calories from carbohydrates. There is no good evidence that low-carbohydrate dieting confers any particular health benefits apart from weight loss, where low-carbohydrate diets achieve outcomes similar to other diets, as weight loss is mainly determined by calorie restriction and adherence. An extreme form of low-carbohydrate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intermittent Fasting
Intermittent fasting is any of various meal timing schedules that cycle between voluntary fasting (or reduced calorie intake) and non-fasting over a given period. Methods of intermittent fasting include alternate-day fasting, periodic fasting, and daily time-restricted feeding. Intermittent fasting has been studied to find whether it can reduce the risk of diet-related diseases, such as metabolic syndrome. A 2019 review concluded that intermittent fasting may help with obesity, insulin resistance, dyslipidemia, hypertension, and inflammation. A 2022 review indicated that intermittent fasting is generally safe. Adverse effects of intermittent fasting have not been comprehensively studied, leading some academics to point out its risk as a dietary fad. The US National Institute on Aging states that there is insufficient evidence to recommend intermittent fasting, and encourages speaking to one's healthcare provider about the benefits and risks before making any significant changes ...

Dukan Diet
The Dukan Diet is a high-protein low-carbohydrate fad diet devised by Pierre Dukan. Description The Dukan diet is a high-protein, low-carbohydrate diet with four phases, each of which has specific rules. History In 1975, Pierre Dukan was a general practitioner in Paris when he was first confronted with a case of obesity. At the time, being overweight or obese was thought to be best treated by low calorie and small sized meals. Dukan thought of an alternative way to prevent patients from regaining their lost weight. He designed a new approach in four phases, including stabilisation and consolidation. After more than 20 years of research Pierre Dukan published his findings in 2000 in his book ''Je ne sais pas maigrir'' (''I don't know how to get slimmer''), which became a best seller. In July 2011, a French court ruled against Dukan in his attempt to sue rival nutritionist Jean-Michel Cohen for libel, after Cohen had criticised his method in the press. In 2013, Dukan, then ...

Protein (nutrient)
Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates: 4 kcal (17 kJ) per gram; in contrast, lipids provide 9 kcal (37 kJ) per gram. The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. Proteins are polymer chains made of amino acids linked together by peptide bonds. During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions. This is crucial for the absorption of the essential amino acids that cannot be biosynthesized by the body. There are nine essential amino acids which humans must obtain from their diet in order to prevent protein–energy malnutrition and resulting death. They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atkins Diet
The Atkins diet is a low-carbohydrate fad diet devised by Robert Atkins in the 1970s, marketed with claims that carbohydrate restriction is crucial to weight loss and that the diet offered "a high calorie way to stay thin forever". The diet became popular in the early 2000s, with Atkins' book becoming one of the top 50 best-selling books in history, and as many as 1 in 11 North American adults claiming to be following it. Atkins died in 2003 and in 2005 Atkins Nutritionals, Inc. filed for bankruptcy following substantial financial losses. There is no good evidence of the diet's effectiveness in achieving durable weight loss; it is unbalanced as it promotes unlimited consumption of protein and saturated fat, and it may increase the risk of heart disease.Longe, Jacqueline L.
