Evidence question
Does increasing dietary protein improve weight-loss maintenance?
Result / effect
In the 12-month DIOGENES extension, high-protein groups regained 2.0 kg less than low-protein groups in the completers analysis; the intention-to-treat difference was 2.8 kg.
Evidence chain
Population
Adults with overweight or obesity after an initial low-calorie weight-loss phase in the DIOGENES extension.
Endpoint
Weight regain during a 12-month maintenance period.
Evidence level
Moderate. Randomized evidence supports context-specific benefit, not a single universally optimal macronutrient target.
What this record does not establish
- This evidence concerns maintenance after an initial weight-loss phase.
- Adherence and food environment influence the observed effect.
- A dietary pattern cannot be reduced to one branded product or supplement.
