The eldest of the Kardashian sisters have all endorsed the QuickTrim line of weight loss supplements. But in June 2010, Kim Kardashian was the only sister endorsing the line since her sister Kourtney was breastfeeding and Khloe was 'fat/considering pregnancy.' The daytime pills are mostly made up of caffeine and the night time pills are a laxative. Kim Kardashian has claimed to have lost 15 pounds on the program, as reported by the Huffington Post.
