So Im 26, 6' 0", and 213lbs. In the last two years I have cut down from 296lbs and obviously feel a ton better physically. I usually feel great mentally as well(happy). I was about 220lbs for around 5-6months and four months ago started lifting heavier and increased intensity with my lifting and cardio routines and have gotten to 213lbs. I started seeing a lot less gains in the last month and so I started taking protein, and eating more lean meats and fish. Anyways, I feel kind of emotional as of the past month or so. I have also been easily irritated by things that I would usually just blow off and not think twice about. I am wondering if its possibly the protein supplements?
