Why Slow and Steady Actually Wins

Studies consistently show that people who lose weight slowly (0.3–0.5 kg/week) keep it off longer than crash dieters. The reason: you don't lose muscle, your metabolism stays healthy, and you build habits instead of white-knuckling a temporary restriction.

A modest deficit of 300–500 calories per day means you're barely hungry, you still eat foods you enjoy, and you can maintain the approach for months — not just weeks.

The Healthy Weight Loss Plate — Every Meal
