Carbohydrate-modified diets (low glycemic load, high fiber, or reduced-CHO) are more effective for weight loss or weight regain prevention in individuals with impaired glucose metabolism (prediabetes, IFG, or IGT) compared to those with normal glucose tolerance, supporting the hypothesis of precision nutrition based on glycemic status.

If you have prediabetes or impaired glucose tolerance, you may lose more weight or prevent weight regain by choosing a carbohydrate-modified diet (such as low glycemic load, high fiber, or reduced carbohydrate) compared to a standard high-carbohydrate diet. While the evidence is not yet definitive, this approach aligns with your body's likely insulin resistance. Consult a healthcare provider for testing and personalized guidance.

ModerateQualifiesMEDIUM confidence
Evidence in support of the hypothesis was identified in six of seven retrospective and three of eight prospective studies, which led to a recommendation of CHO-modified diets as a first-line option for people with impaired glucose metabolism.

Why this rating

Based on a mix of retrospective secondary analyses and prospective RCTs, but the authors explicitly state the evidence is 'relatively weak' and calls for more rigorous research.
