Lose 100 pounds in just four months! Really? That's exactly what 26-year-old Edwin Velez from Albertville, Alabama accomplished. Velez made the decision to finally lose the weight after looking at photos of himself from a cruise to the Bahamas. Velez was tipping close to 300 pounds on the scale when he made a promise to himself to lose the weight. Not only to lose the weight, but to get healthy and in shape too.  Velez wanted to lose 100 pounds before the next trip with his friends, which was in four months.

Velez also changed his diet, going from the sweets and the Hispanic food like; tortillas, rice and beans that he was used to eating everyday. He looked to lower the carbohydrates in his diet, and also eliminating sugary drinks and anything carbonated.

Velez made it through the holidays and in March, just a few days before he left for his planned vacation to Puerto Rico, he stepped on the scale again. This vacation, he weighed just over 100 pounds less, reaching his goal and then some.

Here's what Velez told GMA this morning when he appeared on the show:

I would say the switch from drinking nothing but water was, like, the first 10 to 15 pounds and that came off probably within the first two to three weeks. "Adding the cardio to it - which, to me, unless you sweat, it's not a workout - on a daily basis really helped with the weight loss, as well as watching what I ate."
