Clinical Summary (TL;DR)
Energy balance (CICO) dictates the direction of body mass change, while macronutrient distribution and resistance training dictate body composition (fat vs muscle). Calculate your personalized targets instantly using our Macro Split Calculator.

Frequently Asked Questions
How much protein should I consume during a caloric deficit?
During energy restriction, optimal protein intake is 1.8 to 2.4 grams per kilogram of body weight (0.8–1.1 g/lb). This stimulates Muscle Protein Synthesis (MPS) and takes advantage of protein's high Thermic Effect of Food (20–30% TEF).
Are low-carb or low-fat diets more effective for fat loss?
When total calories and protein intake are equated, randomized clinical trials (including the DIETFITS study) demonstrate equivalent fat loss between isocaloric low-carbohydrate and low-fat protocols.
