I need to substitute healthy snacks- what?

Almonds aren't actually that healthy. They have TONS of fat in them but are good if you only want a few since they have a lot of protein. You could try raw baby carrots. I do that a lot. They are sweet and crunchy and they fill you up once you have a lot. Even if you want cheezits and crackers, you can probably still have them in moderation if you buy reduced fat. They taste the same but have half the fat yet fills you up the exact same. (And I actually like the taste of the reduced fat cheezits more than the original!) You could also drink a lot of water because it makes you feel full. Good luck! :)
