The Claim

After significant weight loss in obese adult women, resting energy expenditure is reduced beyond what is predicted by the loss of body mass, and this reduction persists as a metabolic adaptation that impedes long-term weight maintenance.

Description
1 study reviewed
In plain English

After losing a large amount of weight, obese adult women experience a persistent drop in resting energy expenditure that is greater than expected based on their new body size, making it harder to keep the weight off.

See the scientific wording

After significant weight loss in obese adult women, adaptive thermogenesis—defined as a reduction in resting energy expenditure beyond what is predicted by loss of body mass—is commonly observed and persists as a metabolic adaptation that may hinder long-term weight maintenance.

Why this might work

After weight loss, fat tissue shrinks and produces less leptin, while the gut produces less GLP-1. Lower leptin tells the brain to reduce energy burning and increase hunger. Lower GLP-1 reduces signals from the gut to the brain that signal fullness. Together, this causes the body to burn fewer calories at rest and drives increased food intake, making it easier to regain weight.

    After losing weight, these women’s bodies burned fewer calories at rest than expected, even after accounting for how much weight they lost—making it harder to keep the weight off. This is exactly what the claim says happens.
