Postmenopausal African American and Caucasian women performed aerobic exercise 3 or 4 times per week for 6 months. While both groups had similar positive results, the African American women experienced a greater reduction in resting metabolic rate. The sample size…
Compared to lean women, obese women have impaired leptin signaling leading to reduced insulin sensitivity. The defective signaling appears to be related to leptin receptors in subcutaneous fat but not visceral fat. Leptin signals body fat levels to the brain,…
After high fat meals, women preferentially store fat in their legs. Storage in upper body subcutaneous tissue was similar in both sexes…suggesting that the men were preferentially storing the fat as visceral fat. The researchers concluded that this was driven…
The researchers used the drug bromocriptine (a D2R agonist) to simulate higher dopamine levels. Insulin sensitivity and fat oxidation improved. Body weight did not improve during the time of the study, but improved insulin sensitivity and fat oxidation rates should…
