If you can cope with eating a lot less for 2-3 weeks. It helps a lot. The stomach stretches but if you eat to satisfy hunger instead of eating to feel full. And do that for a few weeks. You will begin to notice that you feel fuller sooner. As your stomach shrinks a bit as it’s not stretched with food. Doctor told me that and wow huge difference, but that 2-3 weeks was hard.
It’s not perfect though. Plenty of people get their stomachs stapled to reduce their weight, lose weight, and subsequently gain much of that weight back because they’ve behaviorally overcome their stomachs.
