Why yes. Yes I do.
When starting out, I think capacity is even more important than calories. The more you stretch out your stomach and the muscles around it, the more you can eat (obviously) and the hungrier you'll be when empty.
Working on this does not have to mean stuffing yourself constantly or painfully. If you go even a little past full as regularly as possible (ideally several times a day) it will gradually add up, until big meals start to feel like normal meals.
To kick off the process, make or buy a meal that's easy to count (e.g. chicken pieces, pizza slices) but way too big to finish.Do your best, then take note of how much you could have without feeling sick or sore. That becomes a benchmark/record for you to break every few days to a week, while gradually pushing your limits in between.
Meanwhile I highly recommend trying a vitamin B1 (thiamine) tablet every day for a week to see if anything happens. If you happen to have a B1 deficiency, the sudden boost can greatly increase your appetite. If not, it will at least help your body make use of the food you eat. Vitamin C can help too.
Best of luck.
