Pakistani women have an amazing trick they use to stay slim: they keep a string permanently tied around their forearms.

According to Dr. Drupas, a gentle but constant pressure on the nerves in the forearm stimulates certain glands, particularly those involved in weight control (thyroid, suprarenals).
Why don’t you try it? Find two ordinary rubber bands and place them around your right forearm, one third of the way up between your wrist and elbow.
The rubber bands should exert noticeable pressure without cutting off blood circulation and should not slip or slide when you move your arm. This is not a tourniquet!
For best results, you have to wear the rubber bands constantly,even at night when you sleep. It is also recommended not to wear any other jewelry on the right arm.
