03Satiety and performance effects

Macro shiftTypical benefitWatch for
Protein rise in deficitbetter satiety and retentiontaste fatigue from repetition if not varied
Carbs rise around hard sessionsstronger training throughputevening spikes with low activity can increase appetite noise
Fat rise with low carbs or a ketogenic dietsteadier hunger controlpossible performance drop if too high

04Anti-patterns to avoid

Hit protein first. Keep a fat floor. Let carbs flex with training by pairing macro ratios with personalized macro targets and practical nutrient timing.
