I recently received a slimmer belt and I would like to know how much water the average person looses per day wearing it.
Slimming belts are in general a weight loss gimmick. There is very little evidence that wearing a slimming belt has any effect on weight loss whether the weight loss is from fat or water. Sorry!
Is there any proof that with diet and walking that you can loose weight or inches while wearing these? If no, it does have a personal benefit for me, it is reducing the amount of back pain that I have.
There is no significant evidence that shows these devices have any additional benefit for weight loss over exercise and dietary changes. The belt will act as a support and if you have back pain, it will help keep the area warm and supported which may assist in reducing inflammation.
