Macro partitioning
Low-carbohydrate diets provide short-term improvements in HbA1c and body weight but lack consistent long-term superiority over balanced diets.
Low-carb diets can be useful for short-term metabolic improvement in selected patients, but require clinical monitoring. They are not superior to balanced diets in the long term for everyone.
GoodQualifiesMEDIUM confidence
Low-carbohydrate diets showed short-term benefits for hemoglobin A1c and body weight, although long-term sustainability and safety remained uncertain.
Why this rating
Based on 8 studies included in the review, showing consistent short-term trends but variable long-term data.
