Yea...I've been thru a period of losing weight recently, 2 fights in particular. One fight, lost about 6 pounds in a week, dehydrating and starving, then sauna'd and spit cup to lose another 2.5 lbs right before weigh in. That drained the **** out of me. Luckily guy was ****. Bad way to lose weight. Next time I did it right...lost about 8 pounds in 2 weeks. Lotsa distance running, loading on protein, cutting back on carbs, salts etc, lots of small meals often. Weighed in at 153, ate a pile of food, plus 3 gatorade and a bottle of water before fight (like 3-4 hours) and was 159 before stepping in the ring. Loads of energy and felt strong. Careful when cutting, can not only lose ya the fight...but get yourself hurt in a bad way.
I thought it was something genetic, I've trained with a few black guys and neither of them ever breaks a sweat. Another myth debunked
