Aids in weight loss: A detox retreat aids in weight loss and can be the start of your new journey. Toxins that are flushed out of the body during a detox, such as those in fat cells, can increase your metabolism and allow your body to function at a higher pace. Detoxes, such as this classic detox holiday in Austria, and losing weight go hand in hand, and while it's hard to notice at first, over time the results will be more than you could have imagined.
