Should I go to the gym?
Short answer first. Full logic in the chapter.
Month 1: No gym required. Walking only. You're rebuilding your metabolic foundation — adding gym stress on top of a caloric deficit while your body is still inflexible is too much, too fast.
Month 2+ (Stage 2 — Metabolic Reinvestment):
Now you add resistance training. Not to "burn calories" — to build and protect muscle tissue.
Why muscle matters:
- Each kg of muscle burns ~13 kcal/day at rest vs. ~4.5 for fat
- Muscle is the engine that drives your TDEE upward
- Resistance training creates a 48-hour metabolic afterburn (EPOC)
Minimum effective dose: 3 sessions/week × 45 minutes. Compound movements: squats, deadlifts, rows, presses. Progressive overload.
Don't chase a sweat — chase strength numbers going up.
