In the world of this diet, there are also allies and enemies. There is a recipe for blackberry and tuna mousse, an eggplant and grapefruit appetizer, and all other manner of unholy combinations (in Lagerfeld's world you eat calf's liver with strawberries and stewed plums with absolutely everything). To keep slim, Lagerfeld and his doctor concocted dozens of garish recipes, including baked rabbit spread with fromage frais, fish soufflé, jellied fruit terrine, ham and raspberry mousse, vegetables in aspic, and roast guinea fowl with turnips. Lagerfield and Houdret's preferred calorie-cutting method appears to be creating the most unappetizing meals possible. Houdret's plan recommends that dieters start off by eating 800 calories a day for two weeks, far fewer calories per day than researchers recommend for sustainable weight loss ( women should generally eat at least 1,200 calories per day and men should eat at least 1,500). It involves a restrictive caloric intake, appetite suppressants, food supplements, and substituting some meals with flavored 'protein sachets.' It also eschews exercise because exercise 'runs the risk of making you hungry.' The plan - which Insider absolutely does not condone - is called the Spoonlight program.

Instead, he writes, 'My objective was to get to 154 pounds in a year so I could wear different clothes.' Lagerfeld didn't embark on the diet in order to get healthier, he makes clear. The 2004 tome spills how the designer lost more than 90 pounds over a 14-month period through strict dieting and diet drink consumption. Lagerfeld published 'The Karl Lagerfeld Diet' in partnership with Jean-Claude Houdret, a general practitioner and self-proclaimed diet doctor. He also wrote one of the most horrific diet books of all time.

The German-born Lagerfeld helmed some of the most celebrated fashion houses in the world - including Chanel, Fendi, and Chloé - in his more than 60-year career before dying in 2019 at the age of 85. Monday night, the fashion world will honor designer Karl Lagerfeld with a Met Gala themed in his honor. Account icon An icon in the shape of a person's head and shoulders.
