Eating unhealthy is easy and pushed on you at this point, eating healthy is also fairly easy but takes some planning and resolve and a little more time. Every place has free refills, cheap desserts, bread at every meal, over the top portions, etc. rather than trying to help people make better decisions. The only way it ever gets resolved is to make it more expensive/difficult to eat like shit and a cheaper deal to eat better.
I’ve spent most of my life on the bigger side although not necessarily a fatass, just more a fullback type than a WR or OL. I’ve always eaten fairly well, but one thing that made a difference for me was getting some medical issues resolved. After seeing a cardiologist and getting some things straight, I dropped 40 pounds pretty easily and have held it off with no issues. I need to get down another 20 or so, but just haven’t committed to giving up bread and a few other things.
I felt horrible and extremely self conscious when my weight hit it’s peak. I think most in that group feel the same way, but also feel stuck in their ways with too much uncertainty on how to change.
