Dude as a 50 year old man recently down 100 lbs... it's NOT just ozympic of Monjouro that does it. Trust me. Shots, plus bad diet still (but no sodas.) and walking 3.5-5 miles 4 times a week does it for me.
I got kind of up there in my marriage to my ex-wife, but when we split up I found I had more time on my hands and could make time for working out at the gym, taking walks and eating right. I lost like 85lb in 2011-2012 as a result. At 6'3" I went from like 280lb down to ~195, was benching 200lb, and had a resting pulse of an olympic athlete.
Then I got all romantically involved again, and slowly gained back most of it, decided to focus on my health again, and lost like 50lb last year, got distracted, gained most of that back and now I am teetering on the edge of making extra effort to get in shape again.
I find that only two things work for me.
1.) Being single. So easy to make time for absolutely anything when you are single.
2.) Short stints (~6 month max) of sustained focus, but then I inevitably fall off the wagon afterwards.
It's just so draining to maintain focus on a healthy lifestyle when in a relationship and doing all the other busy work domestic life entails.
