African American women with obesity and low insulin sensitivity lose significantly more fat mass and maintain higher total energy expenditure when following a low-carbohydrate diet compared to a low-fat diet.
If you are an African American woman with obesity and have struggled to lose weight on standard low-fat diets, switching to a low-carbohydrate approach (around 20% carbs, 55% fat) may help you lose more fat and keep your metabolism higher. This benefit is specifically linked to having lower insulin sensitivity, which is common in this demographic. Focus on whole foods, complex carbohydrates, and healthy fats while maintaining a caloric deficit.
A low-CHO diet leads to a greater FM loss in AA women with obesity and low SI, likely by minimizing the reduction in EE that follows weight loss.
Why this rating
Randomized controlled trial with controlled feeding, gold-standard metabolic measurements (IVGTT, DLW), but limited to a specific demographic (AA women) and moderate sample size (n=50 analyzed).

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
