Correct. The initial 2‑month phase is designed to reset your biochemistry through nutrition alone, without relying on workouts to force weight loss. You focus on eliminating fructose and ethanol, controlling clean carb intake, and letting your body switch to burning fat instead of muscle. After this phase, you can return to normal workouts and activities.
Gentle movement like walking is always fine if you feel up to it, but it’s not required for results.
