The video is about a medical product from Herbalife called Thermo Bond. In the video, the distributor shows how the pill actually works, by using a glass of water, some oil and two pills which have been reduced to powder beforehand.
After the oil is dropped into the water and goes at the surface, as any oil would do, due to a lower density than water, the powdered pills are added. In just a matter of seconds, the oil is brought down at the bottom of the glass.
The pill is to be taken about 10 minutes after you eat and has best results if used on “cheat days” – when you decide you’ll forfeit your diet or exercise program for one day in order to take a break.
