Four 10-week phases with maintenance breaks. Each phase has a specific calorie target that adjusts for your new, lighter body weight.
At 40 lbs of weight loss, preserving muscle is critical for metabolic health and long-term maintenance. 2–3 resistance sessions per week is the minimum.
Most weight regain happens in the 6 months after reaching goal weight. Planning the transition to maintenance before you get there dramatically improves long-term outcomes.
