Unfortunately, yes your hunger comes back as do all your cravings, old bad habits, etc.
it can be difficult at first to discern between real hunger & head hunger. Real hunger feels different. I feel restless as if something is wrong. There is always a logical reason I feel hungry (haven’t eaten, missed a meal, didn’t eat much,). If there isn’t a reason to feel hungry or if I crave a specific food, flavour or texture I know it’s head hunger.
Head hunger often passes real hunger doesn’t. If you are still producing too much stomach acid you may have hunger pangs. Hunger pangs & your tummy rumbling usually isn’t a sign of hunger as we were always told - it’s just either too much acid (try taking a ppi or antacid) or your digestive system working properly.
Distractions can help. Go for a walk, craft, read, clean out a cupboard or drawer, ring a friend, check this forum, play a game. Even set a time - I’ll have something to eat in half an hour & then chose a nutrient dense low calorie option. Sipping a warm drink can help too.
Many find counselling very helpful to understand your relationship with food & what drives you to eat (your cravings, emotions, habits, etc.). They’ll also help you work out ways to manage these when they feel like they’re taking over. You won’t stop the but you’ll better identify why you want to eat & work out ways to take away some of their power.
