KaylaChristine, since you are allergic to bananas, you could sub in canned coconut milk to thicken it up. The stuff in the can is very thick (it's not the same as the drinkable stuff in the carton).
Coconut oil is also very good for you. Maybe pick up peanut butter, or powdered peanut butter (PB2, or just peanut flour). Avocados are very filling. Chia seeds are super healthy and will become a gel-like consistency if you don't drink the smoothie right away (which could be a good thing).
I really like this recipe: http://ketodietapp.com/Blog/post/2015/0 ... o-Smoothie
Smoothies are great because you can pretty much throw anything in the blender and it all works out fine. Spinach is surprisingly tasteless when mixed in with other stuff.
I bought some psyllium husk I plan to use in smoothies to make sure the pipes don't clog, if you know what I mean.
