Nope, it was a voluntary 1000 calorie a day diet for 100 days. He wanted to see if losing weight would help his hypertension. Yeah, he looks bad, he pushed himself too hard too fast. Plus he is 60 years old, it probably wasn’t wise to starve himself like that.
Had he done 2000 calories a day over 150 days instead of 1000 in 100 I’m sure he would look a lot better.
