Dec. 14, 2022 — Millions of Americans struggle to lose weight, do so successfully, and then gain most of it back, research shows.
Now, researchers investigating this weight regain after dieting say they might have made progress in understanding why, in a study published in Nature Metabolism.
Eating a high-protein diet after losing weight reduces a specific gut bacterium that’s linked to fat absorption during digestion. Lowering levels of this bacteria – from eating a lot of protein or from antibiotics – could help sustain weight loss.
