Energy balance

Metabolic adaptations (adaptive thermogenesis) resist weight loss, contributing to weight regain after loss.

Expect metabolic slowdown when losing weight. This is a normal defense mechanism. Long-term maintenance requires strategies that account for this, such as resistance training to preserve muscle mass and realistic caloric targets.

GoodSupportsHIGH confidence
There are metabolic adaptations to a reduced-calorie diet when both resting and total energy expenditure decrease to an extent greater than expected on the basis of the measured body weight and composition change.
