Obesity

The impact of a low‐carbohydrate (vs. low‐fat) diet on fat mass loss in African American women is modulated by insulin sensitivity

Obesity (Silver Spring)Published Randomised controlled trial

Authors' conclusion

A low-CHO diet leads to a greater FM loss in African American women with obesity and low SI, likely by minimizing the reduction in EE that follows weight loss.
