Testosterone influences far more than just libido and muscle growth: In this episode, Dr. Jonathan Apasu speaks with Prof. Farid Saad about the crucial role of testosterone in metabolism, insulin resistance, prediabetes, diabetes, and obesity. Together, they explain why testosterone deficiency is often less a matter of age and more a consequence of being overweight, lack of exercise, and metabolic changes.
They also discuss the fascinating question of how testosterone therapy can improve sugar and fat metabolism, why muscle mass is so crucial for long-term health, and why modern weight-loss medications like GLP-1 analogs, while aiding weight loss, can also lead to the loss of valuable muscle mass.
Of particular interest: Prof. Saad explains why the combination of testosterone therapy and GLP-1 medications could be a promising approach for hypogonadal men with obesity in the future.
