Metabolic changes make weight loss maintenance difficult

Nelson Vergel

"On their own, most individuals are rarely able to lose a substantial amount of body weight and keep it off. Although record numbers of U.S. adults have an elevated BMI, more than 80% of respondents with overweight or obesity told a 2013 Gallup Poll that they had lost a large amount of weight at least once in their life. According to the National Weight Control Registry, adults who pursue weight loss through behavioral treatment programs typically decrease their body weight by 7% to 10% during the first year of participation but maintain only about a 5% loss by a year or so after treatment. Only about 20% of U.S. adults have been able to maintain their weight loss."

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
