Kelly Osbourne – 70 Pounds
Kelly Osbourne has always been curvy, but she decided she needed to shed a few inches in 2009. Through a series of fad diets, including the calorie-burning reverse diet which would have her eating pizza for breakfast and oatmeal for dinner, she ended up losing 70 pounds.
Currently, she’s one of the most popular faces of the mushroom diet, the hottest new trend in the UK. According to those who have tried it, you’re supposed to replace your lunch or dinner with a mushroom-based dish for two weeks. Apparently, this helps you lose 4 to 10 pounds in the said period of time. Osbourne’s body transformation surely gives her good a credit report.
