i know exactly how you feel. April is killing my weightloss with lots of family gatherings/meals.
i agree with the salad and soup route. ask for dressing to be on the side too. that'd control how much you have. as for restaurants, it all depends on where you go too... maybe suggest healthier locations to the family? Like Vietmanese has tons of soupy noodles that aren't very fattening. Or salad bars if you can convince your meat-loving friends. I like to order healthy sandwiches. Avoid deep frying restaurants at all cost!
i think it's okay to be hungry before your next meal. snacks inbetween meals are okay as long as it's reasonable. like an apple here as opposed to a candy bar.
good luck!
EDIT:
I JUST found this online. Hope it helps!
