Frequently Asked Questions
What are macronutrients?▾
Macronutrients are the three energy-providing nutrients: protein and carbs (4 kcal per gram) and fat (9 kcal per gram). Tracking them helps you hit calorie targets while preserving muscle and health.
Do I need to count macros to lose weight?▾
Calories matter most for weight change, but balancing macros helps keep you full, maintain muscle and stay healthy during a cut. A protein-focused split is especially useful for weight loss.
