Why does T3 thyroid hormone aid in weight loss?
DR. Z: Since T3 is a potent stimulator of metabolism, this degree of elevated T3 production probably “upregulated” the metabolic rate of these subjects. This, in essence, then acts as a modulator of the weight set point, decreasing it to levels associated normally with T3 levels of a younger individual. The mechanism for 7-Keto to increase T3 is not clearly understood, but I would suspect it is linked to its ability to antagonize glucocorticoid action on the hypothalamus and pituitary, which suppresses the release of thyroid hormone. Again, it should be noted, this significant yet safe increase in T3 activity is one of the reasons people using 7-Keto lost weight. Their metabolism and set point had been reset at a higher rate, and they were therefore able to resist any metabolic adaptations. RS: Can people take 7-Keto on its own and expect to lose weight? Dr. Z: There are no magic bullets in weight loss. 7-Keto cannot produce weight loss without a healthful diet and regular exercise. Ho
