He's been known to walk around pretty light while In camp @ lightweight. Eats mostly raw vegan, very little animal food or anabolic / building foods and restricted calories. Take a guy on an extremely restricted diet and feed him some meat, carbs, calories and he'll blow up pretty fast. Can attest to this from experience.
Who knows what he was cuttin for the first fight. Given the fact that he was walking around @ 175 for lightweight and that he was pretty far removed from camp / pigging out and drinking beer in cabo and the fact that he had a bit of fat on him during the fight..you have to figure he cut at least 10. Probably more. And he was much bigger for the 2nd fight so you just have to kind of read between the lines on that one
I'll also say that cutting is a broad term and doesn't just mean dehydrating themselves In the sauna or bath. It also entails cutting out certain carbs,drinking massive quantities of water to eliminate salt retention, natural diuretics, removal of sugar and some anabolic foods, eating more fruits and vegetables / salads. If a guy says they're cutting 20 pounds, It doesn't always mean they're bleeding themselves dry In the sauna. Especially today, more fighters are emphasizing "doing right" which means through diet, nutrition and working their fucking asses off. Post weigh In they probably wont be gaining back as much weight as someone who cut the same amount In water, but take a guy who's been on an extremely restricted diet for X amount of time and feed him a bunch of meat, fish, eggs and CALORIES..and they'll definitely put on a good amount of weight. Just wanted to clarify the cutting thing since you said cutting means dehydration.
It means a lot of things
