The latest fad weight loss pill is 7-Keto DHEA. It's been featured and recommended on the show "Dr. Oz", and their website claims:
7-Keto works to counter this [dropping DHEA levels] by stimulating the thyroid to permanently raise your metabolism’s set point, or your resting metabolic rate, which is based on your body’s amount of fat and muscle.
Is there evidence supporting the claim that 7-Keto DHEA can permanently raise the metabolic rate in humans?
