Foods high in easily digestible carbohydrates e. The amount of carbohydrate allowed varies with different low-carbohydrate diets. A popular misconception driving adoption of the diet for weight loss, is that by reducing carbohydrate intake dieters can in some way avoid weight gain from the calories in other macronutrients.
Although such diet recommendations mostly involve lowering nutritive carbohydrates, some low-carbohydrate foods are discouraged, as well e. Low-carbohydrate diets improve cardiovascular risk factors and are effective for achieving weight loss.
A systematic review of 62, participants in 10 dietary trials found that reducing dietary fat intake had no effect on coronary heart disease and had no effect on overall mortality.
The authors of this meta-analysis conclude that the available evidence from randomized controlled trials does not support the recommendation of the - Dietary Guidelines for Americans that people reduce their fat intake. As with other diet plans, people who maintain a low-carbohydrate diet lose weight. In persons with diabetes mellitus Type 2, a low-carbohydrate diet gives slightly better control of glucose metabolism than a low-fat diet.
Potential favorable changes in triglyceride and high-density lipoprotein cholesterol values should be weighed against potential unfavorable changes in low-density lipoprotein cholesterol and total cholesterol values when low-carbohydrate diets to induce weight loss are considered.
As of it appeared that with respect to the risk of death for people with cardiovascular disease, the kind of carbohydrates consumed are important; diets relatively higher in fiber and whole grains lead to reduced risk of death from cardiovascular disease. High refined-grain diets do not. As of in commenting on a study in the Journal of the American Medical Association, a spokesperson for the American Dietetic Association reiterated the association's position that "there is no magic bullet to safe and healthful weight loss.
Fiction" campaign in , the ADA stated: Excess calories from carbohydrates are not any more fattening than calories from other sources. As of [update] the AHA stated categorically that it doesn't recommend high-protein diets. Some of these diets restrict healthful foods that provide essential nutrients and don't provide the variety of foods needed to adequately meet nutritional needs. People who stay on these diets very long may not get enough vitamins and minerals and face other potential health risks.
Eckel , past president, noted that a low-carbohydrate diet could potentially meet AHA guidelines if it conformed to the AHA guidelines for low fat content.
The position statement by the Heart Foundation regarding low-carbohydrate diets states: Low-carbohydrate diets became a major weight loss and health maintenance trend during the late s and early s. Because of the substantial controversy regarding low-carbohydrate diets, and even disagreements in interpreting the results of specific studies, it is difficult to objectively summarize the research in a way that reflects scientific consensus.
Although there has been some research done throughout the twentieth century, most directly relevant scientific studies have occurred in the s and early s and, as such, are relatively new and the results are still debated in the medical community.
A systematic review studying the effects of a low-carbohydrate diet LCD on weight loss and cardiovascular risk factors showed that the diet that was studied was associated with significant decreases in body weight, body mass index , abdominal circumference, blood pressure , triglycerides , fasting blood sugar , blood insulin and plasma C-reactive protein , as well as an increase in high-density lipoprotein cholesterol HDL.
Low-density lipoprotein cholesterol LDL and creatinine did not change significantly. The study found the LCD was shown to have favorable effects on body weight and major cardiovascular risk factors but concluded the effects on long-term health are unknown.
The study did not compare health benefits of LCD to low-fat diets. A meta-analysis published in the American Journal of Clinical Nutrition in compared low-carbohydrate, Mediterranean, vegan, vegetarian, low-glycemic index, high-fiber, and high-protein diets with control diets. The researchers concluded that low-carbohydrate, Mediterranean, low-glycemic index, and high-protein diets are effective in improving markers of risk for cardiovascular disease and diabetes.
Advocates of low-carbohydrate diets generally dispute any suggestion that such diets cause weakness or exhaustion except in the first few weeks as the body adjusts , and indeed most highly recommend exercise as part of a healthy lifestyle. Some critics imply or explicitly argue that vegetables and fruits are inherently all heavily concentrated sources of carbohydrates so much so that some sources treat the words 'vegetable' and 'carbohydrate' as synonymous. Thus, in absolute terms, even sweet fruits and berries do not represent a significant source of carbohydrates in their natural form, and also typically contain a good deal of fiber which attenuates the absorption of sugar in the gut.
Most vegetables are low- or moderate-carbohydrate foods in the context of these diets, fiber is excluded because it is not a nutritive carbohydrate. Some vegetables, such as potatoes , have high concentrations of starch, as do maize and rice. Most low-carbohydrate diet plans accommodate vegetables such as broccoli , spinach , cauliflower , and peppers.
Nevertheless, debate remains as to whether restricting even just high-carbohydrate fruits, vegetables, and grains is truly healthy. Contrary to the recommendations of most low-carbohydrate diet guides, some individuals may choose to avoid vegetables altogether to minimize carbohydrate intake.
Low-carbohydrate vegetarianism is also practiced. Raw fruits and vegetables are packed with an array of other protective chemicals, such as vitamins, flavonoids , and sugar alcohols. Some of those molecules help safeguard against the over-absorption of sugars in the human digestive system. Some evidence indicates the increasingly large percentage of calories consumed as refined carbohydrates is positively correlated with the increased incidence of metabolic disorders such as type 2 diabetes.
Some evidence indicates the human brain — the largest consumer of glucose in the body — can operate more efficiently on ketone bodies. In , the Canadian government ruled that foods sold in Canada could not be marketed with reduced or eliminated carbohydrate content as a selling point, because reduced carbohydrate content was not determined to be a health benefit. The government ruled that existing "low carb" and "no carb" packaging would have to be phased out by In , John Rollo reported on the results of treating two diabetic Army officers with a low-carbohydrate diet and medications.
A very low-carbohydrate, ketogenic diet was the standard treatment for diabetes throughout the nineteenth century. In , William Banting , a formerly obese English undertaker and coffin maker, published "Letter on Corpulence Addressed to the Public", in which he described a diet for weight control giving up bread , butter , milk , sugar , beer , and potatoes. In the early s Frederick Madison Allen developed a highly restrictive short term regime which was described by Walter R.
The process was halted if sugar appeared in the person's urine. In , Richard Mackarness M. Mackarness also challenged the "calorie theory" and referenced primitive diets such as the Inuit as examples of healthy diets with a low-carbohydrate and high-fat composition.
The "Stillman diet" is a high-protein , low-carbohydrate, and low-fat diet. It is regarded as one of the first low-carbohydrate diets to become popular in the United States. In , Robert Atkins published Dr. Diet To Go ships all over the continental U.

With the Core or Uniquely Yours plans you can select your own meals to receive — so you have the flexibility to choose your favorites. Some plans allow a few solid foods, but are still called fasts because they provide so few calories. Not all fasts are created equal. Some can be perfectly safe, such as medical fasts supervised by a physician. Religious and cultural fasts are typically undertaken as an act of devotion, last from hours, and are not intended to promote weight loss. Fasts lasting a day or two are unlikely to be dangerous for most healthy adults.
But high-risk people, the elderly, anyone with a chronic disease, pregnant women, and children are advised against any type of fasting. The real danger lies in staying on the fast for prolonged periods, anywhere from three days to a month. When you dramatically reduce your calorie intake, you will lose weight. But it can also cause all kinds of health problems, including muscle loss. Further, when you start fasting, your body goes into conservation mode, burning calories more slowly.
Keep in mind that the initial weight lost on a fast is primarily fluid or "water weight," not fat.
