Well, only testing it out will really tell you.
Try it and see what happens!
If in 3 months, you've put on fat...or you're not gaining, that's your answer. Actually, one month will probably be enough to tell you.
Ghost is right though.
Is it really that much of a hassle to eat a handfull of nuts and a couple hardboiled eggs in between lunch and your next meal?
Throw some nuts in one, some hardboiled eggs, or lowfat turkey slices, whatever...in another one.
Throw the bags away when you're done.
