Good luck!! Are you following a doctor's advice or did you find your own plan? It does get easier, as you continue your stomach will get used to smaller portions. If you're meeting a calorie goal but still feel hungry, you might want to eat something higher-protein. Tofu and eggs are great for low-calorie protein. And a snack every once in a while won't do much damage :)

Resistance training can help you with that.

Google tells me protein is your friend. You might want whey protein supplements, or eggs and tofu for lean protein. Beans too.
