For meals i eat until full, some restaurant food portions are too small so i come home and top up. if I'm hungry in between meals i eat carbs and fruit, not junk like crisps, chocolate bars, pastries etc. If someone is insulin resistant obviously that's an issue, if not no problem, it's ok to have insulin spikes. It's nice eating when you want, feels better. All blood numbers, BP, RHR are good, I appreciate that's bad news for the low carb people
