  • Low-carbohydrate diet

    serch.it?q=Low-carbohydrate-diet

    A low-carbohydrate diet restricts the amount of carbohydrate-rich foods – such as bread – in the diet.Low-carbohydrate diets or carbohydrate-restricted diets (CRDs) are diets that restrict carbohydrate consumption. Foods high in carbohydrates (e.g., sugar, bread, pasta) are limited or replaced with foods containing a higher percentage of fats and moderate protein (e.g., meat, poultry, fish, shellfish, eggs, cheese, nuts, and seeds) and other foods low in carbohydrates (e.g., most salad vegetables such as spinach, kale, chard and collards), although other vegetables and fruits (especially berries) are often allowed. There is a lack of standardization of how much carbohydrate low-carbohydate 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% carbohydrate content. Disadvantages of the diet might include halitosis, headache and constipation, and in general the potential adverse effects of the diet are under-researched, particularly for more serious possible risks such as for bone health and cancer incidence. Carbohydrate-restricted diets can be as effective, or marginally more effective, than low-fat diets in helping achieve weight loss in the short term. In the long term, effective weight maintenance depends on calorie restriction, not the ratio of macronutrients in a diet. The hypothesis proposed by diet advocates that carbohydrate causes undue fat accumulation via the medium of insulin, and that low-carbohydrate diets have a "metabolic advantage", has been falsified by experiment. For people with potential cardiovascular health issues, a low-carbohydrate diet appears to be as effective as low-fat dieting in mitigating risk. Carbohydrate-restricted diets are no more effective than a conventional healthy diet in preventing the onset of type 2 diabetes, but for people with type 2 diabetes they are a viable option for losing weight or helping with glycemic control. Carbohydrate-restricted dieting does not appear to be helpful in managing type 1 diabetes. An extreme form of low-carbohydrate diet – the ketogenic diet – is established as a medical diet fot treating epilepsy. Through celebrity endorsement it has become a popular weight-loss fad diet, but there is no evidence of any distinctive benefit for this purpose, and it risks causing a number of side effects. The British Dietetic Association named it one of the "top 5 worst celeb diets to avoid in 2018".

  • Atkins diet

    The Atkins diet, also known as the Atkins nutritional approach, is a commercial weight-loss program devised by Robert Atkins. The Atkins diet is classified as a low-carbohydrate fad diet. The diet is marketed with questionable claims that carbohydrate restriction is critical to weight loss. There is no good evidence of the diet's effectiveness in achieving durable weight loss and it may increase the risk of heart disease.
