When I get hungry, I eat. It's your body;s way of telling you you need more calories to keep up with your activitie.
And I'm getting good at it too! I had leftovers (Bulgur, lentils, and sauteed veggies), and after I was done, I was still hungry.
I waited a few minutes to make sure it was real hunger, and then I went in and had some watermelon!
Sometimes, it is falso hunger though, and usually if I go drink some water or read something, it will go away, but if it doesn't then I'll snack on something healthy and wholesome (and vegan!)
During weight loss, though, it's different, since you want your body to be eating at a defecit, you need to trick it.
Make 80% of your meals plant based, and just heap on the steamed veggies!! Seriously- allow yourself 2 cups, even more if you want!
Drink lots of water to keep you full, that helps me, and you can always have some healthy low/no cal snacks, like celery, broccoli, tea, watermelon, berries, unbuttered and no salt popcorn
Oh, and switching to whole wheats and grains will help you feel full. Theyre a lot lower oin the glycemic index, and won't cause the insulin spike like refined grains do, not to mention they're loaded with nutrients, like B vitamins, protein, fiber, iron, and others
