The Jimmy Kimmel Live! host wasn’t concerned about his weight until Dr. Oz was a guest on his show in 2010. After the doctor said he was worried about the comedian, Kimmel began dieting. Having two protein shakes and a small dinner every day for eight weeks and later moving on to a 2,000 calorie-per-day regimen helped him drop 25 pounds quickly. Now, the late-night host uses intermittent fasting and other methods to keep his svelte figure, he explained in January 2015. And he is always looking to discover the best methods to stay in shape and lose weight.
