High Protein Diet Overview
"High-protein diets can be roughly divided into two categories. Some high-protein diets restrict carbohydrates in order to create ketosis, a physical state where the body is forced to burn fat reserves because its preferred fuel, carbs, is unavailable. But they do not restrict calories. The Atkins Diet is the best-known example of a ketogenic diet.
In other high-protein diets, calories are restricted while emphasizing the consumption of protein. The theory behind these restricted calorie diets is that protein satisfies hunger, making these diets more tolerable. The Dukan Diet in its first two stages is a good example of a calorie-restricted high-protein diet."
Length of diet plan: The length of high protein diets varies by regimen— from a week to a lifetime.
