If you don't trust their calculators just measure out a smoothie yourself on mfp. If you are so much of a pussy you can't force yourself to drink a smoothie then go eat fast food or something. If their smoothies have too much sugar for you (idk how but ok) then just make your own.
3500 calories == 1 pound. It sounds like youre already in a deficit anyway. You might gain some useful muscle but unless you start eating a massive surplus everyday you're not going to "balloon"
tldr: yeah eat more, youll feel better
