Contrary to the popular belief that estrogen is solely a female hormone, men can also be estrogen dominant. In men, progesterone is produced in the adrenal and testicular tissue. When men reach their forties, falling progesterone levels lead to a fall in testosterone levels. As both the progesterone and testosterone levels decline, the male body becomes estrogen dominant.

Chapter 2 will help you to understand how age, body fat, and environmental toxins can join forces to sabotage your inner hormonal equilibrium.

Eating every three or four hours will prevent you from getting too ravenous. Curb your hunger with a midafternoon snack so you aren’t starving by dinnertime. “If you wait too long or build up this intense hunger, you’re more likely to choose those convenience foods and more likely to overeat at that next meal,” says Armul. “You want generally smaller to moderate portion sizes because they’re an easier load for your body.”
HOW TO MAKE IT: Combine piece of salmon, ¼ avocado, half a tomato, and a handful of frozen corn (which will thaw by lunchtime) with 2 cups of lettuce of your choice (we like romaine).

Save half of the dressing for a salad later this week.
