> You don't have to worry about eating another meal or two.
You do realize for many overweight people eating isn't something to worry about but to look forward to? It's not that we don't understand thermodynamics. It's just a big part of enjoying being alive.
And? If a big part of enjoying being alive is eating freely without worry then do that and be happy with whatever body shape you end up with. That doesn't seem where OP is coming from though.
In my experiment with alternating day fasting, I was surprised how quickly I was able to look forward to a meal that was 18 hours away.
Was I interested in eating sooner? Yes. But you learn quickly the difference between hunger as desire and hunger as need. 99% of what we feel in our lives wrt food is hunger as desire.
Caloric restriction is a requirement of sustainable weight loss, there are no weird hacks around it.
The fundamental thing is calories in/calories out. Then you just need to find a strategy that helps you implement that that you can adhere to - keto, intermittent fasting, low fat, whatever. Track your calories under a few regimes and see which is easiest to stick to. People might argue one is better than the other, and that could well be true, but I think only at the individual level. What works for me might not work for you.
What worked for me (losing 14kg in 6 months) was only having two meals a day (lunch and dinner, breakfast was a coffee), and having the same (low calorie) meal for lunch every day.
