Exercise and diet needs to be added with this supplement. Workout 3-4 times a week for 30-40 mins on top of a Keto diet. The amount of weight you lose is totally dependent on you. Obviously adding exercise to your regimen will speed up your weight loss. Cutting out things that are common “stall” causers is also a good thing. Artificial sweeteners, dairy, wheat products and by products (wheat gluten, wheat flours, and anything with an identifiable wheat product in it). Water weight loss is common when you first start a low carb diet. Ketosis has a diuretic effect to it that can cause many pounds of weight loss in only a few days. While I hate being the bearer of bad news, this isn’t fat. But on a side (and more positive) note, that shows that your body is starting to adjust itself into a fat burning machine!
