HOW SAFE ARE HIGH PROTEIN AND LOW CARBOHYDRATE DIETS: The theory behind high protein and low-carbohydrate diets is that if dieters avoid foods containing carbohydrates i.e. starches or sugars — they will shed pounds. Such diets eliminate or dramatically restrict the intake of fruit, fruit juice, starchy vegetables, beans, bread, rice, cereals, pasta and other grain products, and all other foods containing carbohydrate, leaving a limited diet of foods that contain primarily fat and protein viz. meat, cheese, nonstarchy vegetables, and very little else. As the diet proceeds, the carbohydrate restriction relaxes somewhat, but fatty, high-protein foods continue to dominate the dieter's platter. Low-carbohydrate diets typically include quantities of cholesterol, fat, saturated fat, and protein that exceeds the recommended safe limits set by the National Academy of Sciences, and are often low in fiber and other important dietary constituents. “High-protein diets are not recommended bcoz they restrict healthful foods that provide essential nutrients and do not provide the variety of foods needed to adequately meet nutritional needs. Individuals who follow these diets are therefore at risk for compromised vitamin and mineral intake, as well as potential cardiac, renal, bone, and liver abnormalities overall.” So one should follow the principle of healthy and balanced eating to lose weight. read more..
