3 The Yo-Yo Effect Your body's own metabolism causes the yo-yo effect. When you go on a crash diet, your body thinks you're starving. It responds by lowering your metabolism to burn fewer calories. When you start eating again, you'll gain weight even more easily, and it could take months or years for your body to readjust. When you participate in multiple cycles of crash dieting, your body begins to break down muscle faster than fat. The more weight you lose on a starvation diet, the more your metabolism slows. The slower your metabolism, the more weight you gain when you start eating again. Crash dieting can easily become a never-ending cycle of rapid weight loss followed by rapid weight gain.

4 Metabolism Slows BMR Formula (person of moderate activity) Women: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years ) Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in year ) Alan as example: 66 + (6.23 x 165) + (12.7 x 70) – (6.8 x 52) = 1094 + 889 - 354 = 1629
