It’s difficult when you’re going through all that hormonal stuff; but I’ve found that it evens out over the long haul, even if you cheat now and then.
My husband lost 65 lbs. by being really religious on the South Beach sort of diet for a while. But he has now kept it off for years, even though he cheats about half the week, now. (Can’t keep an Italian man away from his spaghetti and lasagna, forever ;-)
It helps that he really likes meat; it’s harder for me, because I don’t really like meat; but I can go long enough to lose weight, and keep it off by being careful.
Everyone is different. I’ve tried low-fat, and low carb; the difference is that with low-fat I needed a lot of exercise - and had to carry around a lot more food! The low-carb way cuts down your appetite, and you just don’t want to eat so much after the first few days...
Low fat for decades - kept gaining weight, LDL too high, HDL too low, triglycerides too high, eventually started to become insulin resistant and felt like I was starving all the time.
Low Carbs - no longer starving, stopped weight gain, lipids and triglycerides went back to normal. Eating bacon, eggs, and butter again makes up for the lack of toast. LOL
