It does work. I haven't seen the numbers on the scale change much lately but at least they aren't going up. I was in france on vacation recently and ate so much of that great bread with the high fat butter and didn't gain. We rented bikes and also walked a ton.
I definitely see a difference in my body. Had to replace all my clothes because they were hanging off me like sacks.
The best part was seeing family I haven't seen in a long time last night. They called me skinny!
