Welcome!

It's not a straight line of loss. If you are like I was, there are even days you gain.

Also you may be gaining lean muscle, which cubic inch for cubic inch weighs more than fat. How do the clothes fit?

Keep in mind that along with the 20 carb limit, your fat should be at least twice as much as your protein.

Also you do have to keep calorie count to a reasonable level, and it helps if you exercise. If you are in ketosis, your body will burn fat instead of sugar, so exercising, even if it's a brisk walk, will help.
