Energy balance

Weight loss therapies, including bariatric surgery and hypocaloric diets, inevitably lead to skeletal muscle catabolism, particularly during rapid weight loss phases.

When you start a diet or surgery, expect some muscle loss. To protect your muscle, ensure you eat enough protein and engage in resistance training, as rapid weight loss makes muscle loss more likely.

GoodSupportsHIGH confidence
Bariatric procedures are becoming increasingly common and almost invariably lead to skeletal muscle catabolism, at least in the initial rapid weight loss phase, characterized by profoundly negative energy balance [50]; low- or very-low-calorie diets are associated with similar qualitative changes although to less pronounced degrees [23, 51].
