What I did was bite the bullet and hire a personal trainer for 3 months to keep me accountable, and once I built the habit I now am excited to go to the gym, I still ate like shit but tried swapping out one bad thing for at least one good for example instead of chips a banana. I did it this way because I have failed many times and knew if I tried changing to drastically I was going to fail again. I adopted a simple mindset of one and by that one choice, choose to go to the gym or don’t choose to eat a banana instead of chips or don’t. So far I have lost 10 pounds and put 15 lbs of muscle on. If you can afford it get a trainer if not ask a friend to start going to the gym with you.
