Weight cycling

Ultimately, the dieter reverts to their old eating habits, now with the added emotional effects of failing to lose weight by the restrictive diet.

The process of regaining weight and especially body fat is further promoted by the high metabolic plasticity of skeletal muscle.

The Summermatter cycle[8] explains how skeletal muscle persistently reduces energy expenditure during dieting.

In addition, food restriction increases physical activity which further supports body weight loss initially.

[11] A 2021 systematic review and meta-analysis found that "weight cycling was a strong independent predictor of new-onset diabetes".
