The more your body slows down its calorie burning after losing weight, the more likely you are to eat more than you burn — which makes you gain weight back.

High Compared with Moderate Protein Intake Reduces Adaptive Thermogenesis and Induces a Negative Energy Balance during Long-term Weight-Loss Maintenance in Participants with Prediabetes in the Postobese State: A PREVIEW Study

Randomized Controlled Trial

Human

2020 Mar 1

This study found that when people’s metabolism slows down after losing weight, they tend to gain weight back — and when their metabolism doesn’t slow as much (thanks to eating more protein), they stay in a calorie deficit and keep the weight off. The data shows a strong link between slower metabolism and weight gain, just like the claim says.

After losing weight, the body slows down calorie burning to save energy — but eating more protein stops this slowdown, so the body burns calories at the expected rate again.

After losing weight, people with prediabetes who eat more protein burn more calories at rest and end up in a calorie deficit, which could help them keep the weight off longer.

When you eat more protein after losing weight, your body holds onto more muscle instead of breaking it down.
