I have a friend who regularly does “iron man”-type events. She’s way fitter than I am. She’s also fat. She just don’t look good naked. Reason is, as she happily admits, is that she can’t stop eating cakes.
It all depends what your goals are. If your aim is to lose fat and keep it off, in the most painless possible way, I’d just go with a low-carb high-fat regime. It’s foolproof. It works for anyone. And as mentioned, if you’re doing some serious workouts, you don’t need to get obsessive about it - just dropping the junk food and sweets is going to get you 80% of the way there. Slight complication (I think you mentioned this earlier) is that a lot of the things we think of as “normal” are actually loaded up with sugar and processed starches.
If you’re regularly doing high-power endurance events, then (experimentally speaking) a low-carb, high-fat diet with sugars consumed during the event gives you a serious performance advantage.
