This shyt happened to me a few years ago when I was working non stop. What kinda saved me is that my body is constructed weird, I'm stocky as hell. 6 foot, 255 lb with 40 in thighs and wear size 15 - 16 shoes, my lower body can support added weight without too much consequence.. I used to weight around 300 when I was playing tackle in football but the true problems pop up with getting sick regularly, thyroid issues (now), mood swings, etc.. I know my diet was the issue but it's hard with the work that I do, it was easier to go to Mickey D's and call it a day then being disciplined and preparing my meals beforehand. I'm getting there, I'm too old to be fukking around like I'm still in my early 20s. I'm going to throw up the link for this dudes diet by blood type joint..you can do it bro.
