Compare High-Protein, Low-Carb, and Balanced Diets

For a 30 lb goal, a high-protein plan (about 500 cal/day gap) reaches it in roughly 60 weeks, a low-carb plan (about 600 cal/day gap, with early water loss) in about 50 weeks, and a balanced plan (about 400 cal/day gap) in about 75 weeks. The chart ranks them by weeks to goal; the real difference is which one you can follow consistently, not the small math gap.
