I have to tell you, don't waste your money. I tried Trim Spa a few months ago and all it did for me was make me go into a stall!! I was wanting to speed up weight loss for a class reunion I had and it did nothing for me. I took the Trim Spa faithfully as it said in the directions and nothing. Not even one ounce of weight loss. I think Trim Spa might work for a "standard diet" but I don't think it works in combination with Atkins. Everyone is different but both my husband and I tried Trim Spa and it didn't work. I was really bumed because I heard it has worked for a few hollywood people like Anna Nicole Smith too but seriously it did nothing for me. HTH!
