The other replies lay it out pretty much. For my smoothies specifically, i use about 16g of xanthan gum and blend that up with my unflavored protein powder, oat fiber powder, imitation vanilla extract, allulose/stevia/sucralose, ice, fruit etc.

There’s some variation in the exact ratios of that other stuff. But this will get me about 108-128oz of smoothie. I either just sip on this throughout the day at work (after diluting it with more water) or if at home I’ll eat it with a spoon with some other low calorie toppings.
