Perhaps a little understanding about hunger and how the body works might help.
While you're physically active, your body doesn't feel hungry. Obviously, if you've hit the point of starvation, that's not the case because stomach cramps and other things kick in. But in general, during your routine daily operations if you're physically active your body doesn't feel hunger. Standing, walking around, riding a bicycle, carrying groceries, building some project in the back yard, lawn/garden work, etc.
When you STOP being active, then you feel hunger. This is because the body now has time to divert physiological resources to the task of eating and whatnot. And once you eat, the body now has to divert resources to digestion. The more you eat, the more the body has to divert resources...and the more likely you'll have to deal with uncomfortable aspects, such as stuffed feelings, bloated, gas, etc.
If you simply take in some nurishment, the body can really delay the onset of hunger pangs and the like for a really long time, so long as you're somewhat physically active. Your body has plenty of energy reserves to carry you through and it doesn't have to divert resources to dealing with excessive amounts of food at the same time.
