The phrase refers to a tool designed to estimate macronutrient targets for individuals undertaking a protein-sparing modified fast. This dietary approach, popularized by Lyle McDonald, emphasizes high protein intake while drastically restricting carbohydrates and fats. The calculator facilitates the determination of appropriate protein, carbohydrate, and fat intake levels based on individual characteristics such as body weight, body fat percentage, and activity level.
This tool’s significance stems from its ability to guide individuals through a potentially complex dietary strategy. It offers a structured framework for minimizing muscle loss during periods of caloric restriction. Its historical context is rooted in the evolution of understanding about protein’s role in preserving lean mass, and the recognition that extreme caloric deficits require careful nutritional planning to avoid negative metabolic consequences. By providing calculated macronutrient targets, the tool assists users in adhering to the principles of the dietary approach while minimizing potential risks.
