i am staying still in bolds and losing inches is this common?
i don't know what to do

Do you mean you have lost inches but not pounds? Do you exercise a lot? It's been said before but if you are building muscle your measurements could shrink because a pound of muscle takes up a lot less space than a pound of fat. The muscle is much more "dense".

If you are losing inches you are losing fat, and that's what you're doinng this for, right? Just hang in there and eventually the scale will follow.
