Body Armor Lyte (Peach Mango is just, oh my god) is very low calorie with zero sugar added. There are other flavors, of course. There is ONE problem: slightly high in carbohydrates 😩 But, if diluted or perhaps one 8-10oz bottle per day or every other, just to take the water edge off has worked for me in conjunction with exercise. Good luck!
PS- 530mg of Potassium per serving!
