Weight Loss DietsHigh Protein DietsProteins are composed of amino acids. Proteins perform myriad essential functions for the body including supplying energy and building and repairing tissues. Proteins are obtained from both animal and vegetable sources including eggs, fish and meat. In terms of human nutritional needs, proteins come in two forms: complete proteins contain all eight of the amino acids (threonine, valine, tryptophan, isoleucine, leucine, lysine, phenylalanine, and methionine) that humans cannot produce themselves, while incomplete proteins lack or contain only a very small proportion of one or more. Humans' bodies can make use of all the amino acids they extract from food for synthesizing new proteins, but the inessential ones themselves need not be supplied by the diet, because our cells can make them ourselves. When protein is listed on a nutrition label it only refers to the amount of complete proteins in the food, though the food may be very strong in a subset of the essential amino acids. Animal-derived foods contain all of those amino acids, while plants are typically stronger in some acids than others.There are various versions of this high protein, low carbohydrate diet. However, most recommend large quantities of protein in unrestricted amounts, including red meat, fish, shellfish, poultry, eggs, and cheese. No one diet works for everyone, those who struggle with their weight should meet with a registered dietitian for a nutrition check-up. A now common approach is to modify one of the high-protein diets to be a healthier high-protein diet with the addition of leaner meats, vegetables, and fruit. Extra protein in the diet displaces carbohydrates, which are needed to replace glycogen stores. Glycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is considered the principal storage form of glucose and is found mainly in liver and muscle, with kidney and intestines adding minor storage sites. Plants make starch and cellulose through the photosynthesis processes. Animals and human in turn eat plant materials and products. Digestion is a process of hydrolysis where the starch is broken ultimately into the various monosaccharides. A major product is of course glucose which can be used immediately for metabolism to make energy The glucose that is not used immediately is converted in the liver and muscles into glycogen for storage by the process of glycogenesis. Any glucose in excess of the needs for energy and storage as glycogen is converted to fat. A low-carb diet is designed to minimize the consumption of carbohydrates of all kinds and to maximize the consumption of protein. By lessening the intake of carbohydrates, the body cannot store as much and converts fat to fuel. The high protein diet re-establishes the body's ability to deal with carbohydrates effectively. It switches the body from a carbohydrate-burning machine to a fat burning machine. In other words, in the absense of carbohydrates, the body has to turn to fat as its main source of energy. High protein diets can work wonderfully well. You can experience a fast weight loss and control hunger while you are on it. But remember that most people experience a fast weight gain after getting off a high protein diet. So be careful of that. High protein diets (like all diets) work, but you have to get off it sometime and get back to real eating again. For Your Free Weight Loss Guide, Visit http://www.iLosingWeight.com.
