When your energy level drops, it can be difficult to feel good and look good. Dr. Oz and Dr. Roizen talk about reasons your energy may be low:
- Lack of sleep: Getting eight hours of sleep at night will help your body look good and function better. "Prepare for sleep," Dr. Roizen says. "Remember, only sex and sleep in the bedroom—get the computer and TV out of there."
- Thyroid problems: Thyroid disease can zap your energy, make you gain weight and move much slower. Dr. Roizen says 5 percent of men and 15 percent of women over the age of 60 have hypothyroidism, and when caught, it can be treated effectively. He says people as young as 35 commonly have thyroid problems and should have their thyroid hormone checked if they're experiencing energy loss.
