Only possible? What about self discipline? Over-eating is one of the toughest habits to break but anyone can do it if they can remain determined and disciplined to the task. (I Have lost in excess of 60# 2x and 100# once - Currently I need to lose 50 to get back to 180. This is entirely my own failure to remain dedicated to the task)
Do a carnivore diet. No starving, high satiety factor. Once you switch from a sugar burning metabolism to a fat burning metabolism it gets much much easier to lose weight. Sugar mode - use up glucose stores and you’ll want/need to eat. Fat mode - body has plenty to use for fuel so its happy.
It is very hard for some of us to avoid overeating and “remain dedicated to the task.” I also have lost a lot of weight, then over several years regained all that was lost and more. The best weight loss I had was after moving to Switzerland and being shocked at the price of food. I couldn’t bring myself to paying their exorbitant prices - and that motivation enabled me to lose about 50 lbs. Unfortunately for my weight I had to move back to the U.S. and cheap food again got the better of me. Knowing there is a huge cost to health and for medications tied ultimately to weight should be enough motivation, but not as direct as paying essentially $12 for what at the time was a $1 worth of food.
