What is "90 Day Challenge"?

Anybody is on "90 Day Challenge" program?  I have two people recommending this program to friends around. They have lost 10 pounds within the first month.

Looks like they need to drink their milk shake products. Does that mean people are obligated to pay certain amount of money??

It's a 90 day weight management program. Both hubby and I are on it!
