Dropping weight is different for everybody. I know i walk around at 160 to 165 but i fight at 145 for MMA and 149& under for QG and NAGA. I think its important when you are in a tournament/fight you need to be at the right weight. Just because I could make 135lbs doesnt mean I should be fighting at that weight. You need to find what your body functions the best at and stay at that weight. Eat clean, strength training, cardio and dont drop more than three pounds the day before if your body is not used to it. Think of it like a high end sports car, you spend thousands of days on performance parts,then pay a teeenager in a high school shop class too install them and when your car blows up you wonder way.
