Insulin tends to make women put on fat in the abdominal area so I bet that IS where it is going away from. You know, the belly or apron below the waist in front or rolls around the lower ribs. You could also be losing in a very thin layer all over your body. Have your rings or watch gotten looser yet? That was something that surprised me.

You may also be losing fat but those little fat cells get anxious and try to grab all the water they can to 'plump' themselves up again. They try to stay the same size but get a bit smaller. In a person who stays with LC, there comes a day when the fat cells give up and let go of a bunch of water from each cell. This is the famous "whoosh" or sudden loss of quite a few pounds, seemingly overnight.
