In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy.
Complete nutrition requires ingestion and absorption of vitamins, minerals, and food energy in the form of carbohydrates, proteins, and fats. Dietary habits and choices play a significant role in the quality of life, health and longevity.
Dieting is the practice of eating food in a regulated and supervised fashion to decrease, maintain, or increase body weight. In other words, it is conscious control or restriction of the diet. A restricted diet is often used by those who are overweight or obese, sometimes in combination with physical exercise, to reduce body weight. Some people follow a diet to gain weight (usually in the form of muscle). Diets can also be used to maintain a stable body weight and improve health. In particular, diets can be designed to prevent or treat diabetes.
Diets to promote weight loss can be categorized as: low-fat, low-carbohydrate, low-calorie, very low calorie and more recently flexible dieting. A meta-analysis of six randomized controlled trials found no difference between low-calorie, low-carbohydrate, and low-fat diets, with a 2–4 kilogram weight loss over 12–18 months in all studies. At two years, all calorie-reduced diet types cause equal weight loss irrespective of the macronutrients emphasized. In general, the most effective diet is any which reduces calorie consumption.
A study published in American Psychologist found that short-term dieting involving “severe restriction of calorie intake” does not lead to “sustained improvements in weight and health for the majority of individuals”. Other studies have found that the average individual maintains some weight loss after dieting. Weight loss by dieting, while of benefit to those classified as unhealthy, may slightly increase the mortality rate for individuals who are otherwise healthy.
The first popular diet was “Banting”, named after William Banting. In his 1863 pamphlet, Letter on Corpulence, Addressed to the Public, he outlined the details of a particular low-carbohydrate, low-calorie diet that had led to his own dramatic weight loss.

A healthy diet is one that helps to maintain or improve overall health.
A healthy diet provides the body with essential nutrition: fluid, adequate essential amino acids from protein, essential fatty acids, vitamins, minerals, and adequate calories. The requirements for a healthy diet can be met from a variety of plant-based and animal-based foods. A healthy diet supports energy needs and provides for human nutrition without exposure to toxicity or excessive weight gain from consuming excessive amounts. Where lack of calories is not an issue, a properly balanced diet (in addition to exercise) is also thought to be important for lowering health risks, such as obesity, heart disease, type 2 diabetes, hypertension and cancer.
Various nutrition guides are published by medical and governmental institutions to educate the public on what they should be eating to promote health. Nutrition facts labels are also mandatory in some countries to allow consumers to choose between foods based on the components relevant to health.
The idea of dietary therapy (using dietary choices to maintain health and improve poor health) is quite old and thus has both modern scientific forms (medical nutrition therapy) and prescientific forms (such as dietary therapy in traditional Chinese medicine).
Shape search engine optimization is area of the field of maximum control theory. The normal problem is to get the condition which is maximum for the reason that it decreases a certain cost functional while fulfilling given constraints. Oftentimes, the useful being solved will depend on the answer of confirmed partial differential formula identified on the adjustable domain.
Topology search engine optimization is, in addition, worried about the amount of linked components/restrictions owned by the domains. Such methods are needed since typically condition search engine optimization methods work in a subset of allowable styles which have set topological properties, such as having a set number of openings in them. Topological marketing techniques may then help work about the limitations of natural form optimization.
The Paleolithic diet (also called the paleo diet, caveman diet or stone-age diet) is based mainly on foods presumed to have been available to Paleolithic humans. Wide variability exists in the way the diet is interpreted. However, the diet typically includes vegetables, fruits, nuts, roots, and meat while excluding foods such as dairy products, grains, sugar, legumes, processed oils, salt, and alcohol or coffee. The diet is based on avoiding not just modern processed foods, but rather the foods that humans began eating after the Neolithic Revolution when humans transitioned from hunter-gatherer lifestyles to settled agriculture. The ideas behind the diet can be traced to Walter Voegtlin, and were popularized in the best-selling books of Loren Cordain.
Like other fad diets, the Paleo diet is promoted as a way of improving health. There is some evidence that following this diet may lead to improvements in terms of body composition and metabolic effects compared with the typical Western diet or compared with diets recommended by national nutritional guidelines. Following the Paleo diet can lead to an inadequate calcium intake.
The digestive abilities of modern humans are different from those of Paleolithic humans, undermining the diet’s core premise. During the 2.6 million year long Paleolithic era, the highly variable climate and worldwide spread of human population meant that humans were, by necessity, nutritionally adaptable; in contrast, supporters of the diet assume that human digestion has remained essentially unchanged over time.
THE COLOR and the form is the next studio recording by the American rock-band Foo Fighters. Made by Gil Norton, it premiered through Capitol Details and the group’s own Roswell Information on, may 20, 1997. The record is the debut of the Foo Fighters as an organization, as the band’s past record, Foo Fighters (1995), was generally documented by frontman Dave Grohl and good friend Barrett Jones as a demonstration. After the job ballooned and became a global success, the group convened for pre-production in nov 1996 and earned producer Norton to determine a pop sensibility for the paths. The group strived to make a full-fledged rock and roll record, however the music press forecasted another grunge offshoot.
Primarily encouraged by Grohl’s divorce from shooter Jennifer Youngblood in 1996, the lyricism on the record is considerably more introspective and the music more developed. The album’s keep track of listing was made to resemble a remedy procedure, splitting the recording between up-tempo paths and ballads, reflecting conflicting thoughts. Early periods at Washington plantation studio Keep Creek were poor and led the music group to discard almost all of the recordings. The music group regrouped without drummer William Goldsmith in early on 1997 to track record another time at Hollywood’s Grandmaster Recordings, with Grohl seated in on drums instead. Goldsmith was offended and disgruntled that almost all of his materials was re-recorded and kept the band soon thereafter.
Main singles “Monkey Wrench”, “Everlong” and “My Hero” peaked within the very best ten on USA rock and roll radio, and the recording charted at number 3 in britain. Critics found the record a substantial American rock and roll release of the time, which is now seen as a seminal modern rock and roll album. It had been nominated for a Grammy Honor in 1998 for Best Rock and roll Album. THE COLOR and the form is the Foo Fighters’ biggest U.S. vendor, having sold over two million copies relating to Nielsen SoundScan. The recording was remastered and reissued in 2007 with several benefit paths, celebrating its tenth wedding anniversary.
Diet for a Small Planet is a 1971 bestselling book by Frances Moore Lappé, the first major book to note the environmental impact of meat production as wasteful and a contributor to global food scarcity. She argued for environmental vegetarianism, which means choosing what is best for the earth and our bodies — a daily action that reminds us of our power to create a saner world.
The book has sold over three million copies and was groundbreaking for arguing that world hunger is not caused by a lack of food but by ineffective food policy. In addition to information on meat production and its impact on hunger, the book features simple rules for a healthy diet and hundreds of meat-free recipes. “Its mix of recipes and analysis typified radicals’ faith in the ability to combine personal therapy with political activism.”
“Let’s Get Rocked” is a 1992 single by British hard rock band Def Leppard from their multi-platinum album Adrenalize. The song peaked at #1 on the Billboard Album Rock Tracks chart, #15 on the Billboard Hot 100, and #2 on the UK Singles Chart.
A fad diet or diet cult is a diet that makes promises of weight loss or other health advantages such as longer life without backing by solid science, and in many cases are characterized by highly restrictive or unusual food choices. Celebrity endorsements are frequently used to promote fad diets, which generate significant revenue for the creators from the sale of associated products.
