I lost a little over 40lbs over the course of a year in my mid 20s - and it stayed off a looong time - by eating a yogurt for breakfast, mixed veg and rice or pasta w/out butter for lunch, and then reasonable portions of whatever mom’d made for dinner. Nothing else. No junk, nothing w/sugar in, no snacking other than maybe a handful of nuts or some fruit.
I also gave up pretty much all food w/sugar in for six months when I was in my early 20s. I have no idea how I was disciplined enough to do that at that age. I have never felt better in my life.
Wish I had that kind of discipline now.
