I agree with a PP who says large appetite is often due to a distended stomach capacity where it takes more food to make a person feel satiated.
When I look back on how we ate 10/15 years ago the quantities were huge. 3 course dinners every night (pasta, meat, veg, fruit and/or dessert), 3 pizzas between 2, fixating on “where will we eat?’ if we were going on days out. Fresh bread every day, a well stocked freezer and an overflowing fruit bowl. All healthy, good quality but TOO MUCH of everything. I’m a foodie, love trying new recipes, DH is Italian so there is a bit of a feeder vibe in the family.
Mangia, mangia!
I then had a health breakdown, discovered I was pre-diabetic so went low carb and did intermittent fasting. It reset me (- 15kg and maintaining), my pre diabetes and my stomach’s capacity. DH and DC joined me in smaller portions and expectations. We now have 3 courses over 2 meals and often say “I don’t feel like dessert, let’s have it tomorrow.” Today we had gnocchi/ spiralized courgettes with blue cheese (plus 2 apricots) and were groaning before the end…
Covid and rising prices meant I learned to cook more variety and cheaper than restaurants. We’re down to meals out only on special occasions compared to every 3 weeks. I even offered to cook at home for a significant anniversary (not really in the spirit)! Cutting out alcohol has reduced our budget too. The after effects just aren’t worth it any longer.
So maybe DH’s stomach is crying out to be filled but sending false signals? When I started 16/8 intermittent fasting the hunger pangs were completely bearable and were gone IN A WEEK. It was as easy as skipping breakfast.
