According to the CDC figures, the mean American 18-year-old is close to being considered overweight but would still be accepted in the military in most cases. But about one in five of them is considered obese, the CDC says, and would be at least 15 to 20 pounds too heavy to fight.

Based on the CDC study, we believe it's reasonable to think that at least an additional 7 percent of America's remaining 17- to 24-year-olds would have trouble meeting the military's weight guidelines. The "Too Fat to Fight" study supports the theory that 27 percent of America's youths couldn't serve in the military.

We rate the first lady's statement as True.
