PENN JILLETTE: STRICT DIET

Penn Jillette used to weigh 322 pounds but made a significant body transformation when he lost 100 pounds. As there was a 90% percent blockage in his heart due to his weight, he did something about it. Penn still wanted to see his kids when they grew up and provide everything they needed, so they never have to opt for student loans.

The television presenter decided to lose weight and be healthy again by following a potato diet. With this method, he only ate plain potatoes for 14 days. It was a strict diet, also known as a mono-diet, which had to be followed by eating vegetable stews and salad varieties after the said period.
Without exercise, he still lost so many pounds. He knows that it has some side effects, so after shedding all the weight, Penn decided to transition into a more traditional diet to maintain his ideal weight.
