The last pillar of the 20 Years Younger plan is sleep. According to the CDC, up to 70 million Americans say they don't get enough. Bob says if you're not getting seven to nine hours a night, you are putting your health at risk.
"We know that if you don't get enough sleep, it can actually shorten your life," sleep expert Dr. Ronald Kotler says. "It can contribute to problems like diabetes and obesity."
Most people don't think of sleep as something that can make them fat, but Dr. Kotler says it's definitely a contributing factor. "While you're sleeping, the brain makes this chemical called leptin. Leptin is involved in suppressing your appetite, so that if you're not sleeping enough and you're not making enough leptin, you're going to be hungry all day. And if you're going to be hungry all day, you're going to eat and put on weight...then you put yourself at risk for sleep apnea, and it becomes a vicious cycle," he says.
