Controlled diet + controlled exercise. Freshly prepared daily full-day meals delivery + personal trainer at the gym 2x/week combo is the only thing that ever worked for me. And it worked every time (3 times) in different countries. I would get fat again in between those periods, like I am now, after staying in a rural area without those facilities.

Truth, but I also argue that I am not addressing the underlying emotional traps that I attempted to escape using tobacco and alcohol. Those same mental/emotional traps just shifted/intensified with my eating. Perhaps it is that simple, but I also feel it’s important to address the root factors, which I haven’t, admittedly.

yuck - while the soylent diet might be efficient on short term, it's not sustainable. It's harder at first to eat better, healthier foods (more vegetables and fruits, meat and eggs, less fried foods and stuff with a zillion additives or refined sugars) but so much easier to maintain once the habit is formed. Stuff yourself with whole foods 80% of the time, it's going to be ok to eat a burger with fries or a pizza every now or then, and it doesn't feel like a sacrifice. Bonus: you'll feel the difference in energy levels.
