Frequently asked questions
- What is TDEE?
- Total Daily Energy Expenditure — the calories you burn in a typical day including basal metabolism, activity, and the thermic effect of food. Use a dedicated TDEE calculator (Mifflin-St Jeor or Katch-McArdle) to estimate yours.
- How accurate are weekly weight change predictions?
- The 7,700 kcal/kg approximation is a population average. Individual variation, metabolic adaptation, water retention, and glycogen changes mean actual week-to-week weight fluctuates. Track trends over 4+ weeks.
- How large should a cutting deficit be?
- Research suggests a deficit of 300–500 kcal/day (roughly 15–25%) preserves more muscle mass than larger deficits, especially combined with adequate protein and resistance training.
