Drugs for Weight Loss

One problem with the fluid protein feed is that there is often no carbohydrate. This absence or near absence of protein in the watery protein fast flowerpot result in dramatic weight loss. However, the protein must be converted to glucose to maintain blood sugar levels, and protein is non the opera hat fuel source for the body. It takes almost as much nada to convert protein amino group acids to glucose as are gained, and the nitrogen fraction of the protein molecule can create toxicity problems. Also, heart round irregularities which stomach been fatal have been associated with the tranquil protein regimen. It may be that the escape of carbohydrate in this fast or the lumber of the protein used were factors.2

A big factor in the protein regimen is the source of the dietary amino acids. In many of the liquid protein diets, the source of amino acids was collagen. Collagen is a tough connective waver comprising body parts such as tendons and ligaments. Collagen is usually a meat packing industry byproduct that is l genius(prenominal) sold as food when it is liquified to gelatin. When collagen has been further trim down(a) to its amino acid constituents for liquid protein diets, the product is deficient in the essential amino acid methionine. Hence, the collagen protein is not a go off protein source.3

What this means is that body protein must be broken down to supply the missing amino acid, methionine. As a result, the protein from this liquid protein diet can build up body tissues.

 some other problem with fad diets is lack of vitamins and minerals. This lack of vitamins and minerals may produce a restlessness and uneasiness which results in the attention of the dieter being focused on food. copious simply will not be properly metabolized without the skilful vitamins and minerals, and fat is lacking in vitamins and minerals. Vitamins and minerals may be supplied to the dieter through frequent doses of fresh fruit and vegetable juices. Besides vitamins and minerals, these juices have a proteinsparing effect by providing carbohydrates.5

Another reason for failure of fad diets is that they do not take into consideration the complexity of weight loss and obesity. For one thing, diet alone may not be suitable to produce weight loss. Indeed, it has been shown that a combination of diet overconfident exercise is more effective than diet alone in production of weight loss in the obese person. Another important factor that must be considered even when the diet is sound, is that it is hard to get the obese person to comply with the regime. discipline in nutrition and diet may be inevitable to achieve compliance. Also, a variety of psychological and behavioral procedures be a necessary part of the successful diet program. Thus, diet alone may be inadequate.7

Another fad diet that has been around a long time is the fasting diet. The shell selling book, The Last Chance Diet Book, popularized the liquid protein diet, whose collagen hydrolysate drear pink resulted in seventeen deaths from ventricular arrhythmias, as the people's bodies broke down the heart muscle to get the essential amino acid missing from the collagen hydrolysate. However, after the deficient liquid protein diet liquids were removed from the retail stores, the Optifast diet became popular.
