YES. You will definitely lose weight with Keto. There is a drastic weight loss observable on the first weeks of Keto, mostly water weight. Glycogen (Glucose stores) in the liver together with water is the one initially lost after the first few weeks of keto. Note: Not all glucose stores in the liver completely depletes and is totally used up.
Fat induces satiety to our bodies. This means when you eat fat, you will feel full at an earlier time. If you feel full immediately, then you will eat less. Thus, faster rate of weight loss.
