carb solutions berry yogurt flavor .... the taste is one of my favorites, i've eaten tons without getting knocked out of keto, so i guess they must work !
sidenote... usually on most lowcarb diets, protein intake is not much of a concern since ketosis is protein-sparing, at least for me, it doesn't seem to matter if or whether i concern myself with protein, so all i care about is getting filled, while not getting carbs.... it seems as long as i worry about those two, everything else (including protein consumption) seems to take care of itself...
