FAQ

How much protein do I actually need?
For body recomposition: 1.6-2.2 g/kg body weight. Higher end during a cut (preserves muscle), lower end at maintenance. Eating more doesn't help past ~2.4 g/kg for most.
Should fat or carbs be the variable?
Keep protein fixed by body weight, set fat to 20-30% of calories, let carbs take the rest. This protects muscle and keeps fat-soluble vitamins adequate.
Do macro splits really matter?
Hitting calories + protein matters most. The carb/fat split is minor for fat loss but matters for training performance — higher carbs support heavy lifting and long sessions.
