The "YOU Docs"—Dr. Mehmet Oz and Dr. Michael Roizen—say we're the fattest country in the world because of unhealthy diets and sedentary lifestyles. It doesn't have to be that way, though. They say you can get your health back on track in a mere 90 days with their lifestyle suggestions.

• Yoga
  According to Dr. Oz, yoga helps improve strength and flexibility and can also help control blood pressure and regulate breathing and heart rate.
• Walk Every Day
  Dr. Roizen says you absolutely must walk at least 30 minutes every day. "There's a hurricane? You walk 30 minutes a day," he says. "Earthquake—30 minutes a day. Tornado—30 minutes a day. Snowstorm—30 minutes a day."
• Diet
  As Dr. Roizen says, "food is medicine." For example, a recipe for whole wheat pizza dough with tomato paste can help dramatically reduce your risk of cancer. Dr. Oz also says that salmon is rich in omega-3 fatty acids that can stabilize your heartbeat, lower blood pressure and help you to live longer.
• Exercise and Weight Training
  Stretching, weight-lifting and crunches should all be incorporated into your fitness routine. "A lot of folks think about how fast they run, but you've got to stay limber," Dr. Oz says. "You've got to do some weight training."

According to Dr. Oz, the average 30-year-old woman should be able to do 45 bent-leg push-ups (and five fewer every following decade of her life), and the average 30-year-old man should be able to do 35 regular pushups (and five fewer every following decade of his life). "Those should be national benchmarks," Dr. Oz says.
