Detox Tea
Tea has many health benefits, but detox products are complete BS. The "weight" you lose when drinking this tea is called water weight, according to Health. This is not the same as losing fat, and your body will return to normal once you stop drinking the tea and go back to your old eating habits. In addition to just being a temporary fix, people have also reported getting sick from the teas.
