The point of a well-formulated ketogenic diet is to allow the body to burn stored fat, as well as dietary fat. If your body is metabolizing its fat store, what does it matter whether you are losing weight or not? Even if your body needs to add pounds of muscle tissue, you will still lose fat. Is it losing the fat that is important to you, or seeing a particular number on the scale? Personally, I choose the former, because I love being able to wipe myself again (not to be too gross), to be able to bend over and cut my toenails, to be able to get up from the floor with no chair handy, and to be able to sit in a restaurant booth without my belly getting in the way. Being able to zip up my jacket when I went out to shovel snow this morning didn’t hurt, either! And my recent checkup had my best blood pressure and blood work in decades. What do I care what my scale tells me, so long as all these other things are true?
