Higher baseline total testosterone predicts greater long-term weight loss and waist circumference reduction in both males and females with type 2 diabetes undergoing intensive lifestyle intervention.

If you have type 2 diabetes, your baseline testosterone levels may dictate how effectively your diet and exercise efforts lead to weight loss and waist circumference reduction. Both men and women with higher testosterone tend to see bigger improvements in weight and waist size from lifestyle changes. This suggests that knowing your hormone profile could help tailor your lifestyle prescription for better weight outcomes.
