I went from 190-179 in 24 days on a "24 Day Challenge" that myself and a handful of the guys I do my BJJ/MMA with did. I stayed fairly strong (strength training is my bread and butter) and leaned out a great deal. I recommend this 24DC to anyone and everyone!
It's been about 2mo and I'm still in the 177-182 range. And my metabolism is through the roof still!
Ask me any questions; I love talking about this stuff!
