The Karl Lagerfeld Diet, also called the Spoonlight program, is a diet that was designed by Chef Jean-Claude Houdret and used by fashion designer Karl Lagerfeld to lose 90 lbs in 13 months. The diet focuses on limited consumption of calories and fats, while increasing protein and vegetable intake. There is a book called The Karl Lagerfeld Diet, as well as a website on the diet that sells home-delivered protein supplements. The official protein supplements are supplied by Sun-Rex Paris, a French company founded by Chef Houdret.


The Karl Lagerfeld Diet includes limiting one’s caloric intake to 800-900 calories for the first two weeks while adding protein supplements to avoid losing muscle mass. This diet actually discourages exercise on the grounds that exercise stimulates the appetite. Chef Houdret also promotes using plastic surgery to improve one’s appearance in addition to dieting. There are no free samples or money-back refunds offered for this diet on the website.

Product Features

The Karl Lagerfeld Diet is sold on Amazon for $3.99, however the protein supplements sold on the diet’s official website are pricier at around $50 each including shipping for packets of 7 “sachets” of protein in various flavors. The Karl Lagerfeld Diet sachets of protein cannot be purchased online from any other websites besides the official Sun-Rex Paris website; however, The Karl Lagerfeld Diet book is sold online at most book retailers.

Sun-Rex Paris does not offer any money-back guarantees or refund policies on its official website. It also does not offer any warnings for its products, so customers should consult their family doctors and carefully research each ingredient before using.
