Best Diets: Veronica Mederos

When Veronica Mederos reached 275 pounds, her doctor told her she was morbidly obese. She was diagnosed with Type 2 diabetes and polycystic ovarian syndrome, among other health conditions, so she decided to undergo lap-band weight-loss surgery. After losing about 40 pounds, however, she developed complications and the band had to be removed. She recalls being "devastated" and thinking the failed surgery was her "last chance" to lose weight. But now, largely thanks to the P90X workout regimen, Mederos is down to a healthy 179 pounds.
