Estimated Timeline Scenarios (Non-Guaranteed Approximations)

Conservative Pace (0.5 kg / 1.1 lbs per week)
~20 weeks

A steady daily deficit of 500 kcal preserves basal metabolic rate, minimizes lean muscle breakdown, and significantly improves long-term weight maintenance adherence.

Moderate Pace (0.75 kg / 1.6 lbs per week)
~14 weeks

A 750 kcal daily deficit. Requires disciplined protein intake (1.6–2.2g/kg) and resistance training to safeguard lean skeletal tissue from catabolism.
