Metabolic adaptation
The lower-carbohydrate or lower-GI diets increased HDL-C by about 4% and lowered triglycerides (TG) by 20% compared to the higher-carbohydrate, higher-GI diet.
Practitioners may consider recommending lower-carbohydrate or lower-GI diets to improve HDL-C and reduce triglycerides in overweight adults.
StrongSupportsmedium confidence
The lower-carbohydrate or lower-GI diets increased HDL-C by about 4% (with between diet P-values <0.016) and lowered TG by 20% (P<0.031, compared to the higher-carbohydrate, higher-GI diet).
Why this rating
Based on the randomized controlled trial design.
