Ta-da! Penn Jillette didn't saw himself in half but he's nearly half the man he used to be.

The master illusionist and former "Dancing With the Stars" contestant recently dropped 105 lbs by drastically changing his eating habits. His decision to live a healthier life came after he landed in the hospital due to high blood pressure.

"I was on six very powerful meds to bring the blood pressure down," Jillette told PEOPLE. "My doctor said I needed to get my weight down, and if I brought it down 30 or 40 lbs. it would be a little easier to control. And then he said something in passing that completely blew my mind - he said, 'If you got down to 230, you probably wouldn't need any of the meds.'"

And so, from December through March, Penn went on an "extremely low-calorie program" where he consumed only 1,000 calories a day, allowing him to drop nearly a pound a day.

Aside from losing weight in the triple digits, he's also dropped from a 44 waist to a 34.

Now that Penn is at his goal weight, he stopped his rigid restrictions, but still adheres to a self-imposed diet — no animal products, no processed grains, and no added sugar or salt. But, don't call him a vegan. He took to Twitter on April 8 to clarify that, tweeting, "To be clear: I don't eat many animal products (like none) any more, but 'vegan doesn't describe me well. There are many unhealthy vegans."

The way the "Wizard Wars" star describes it is, "I eat unbelievable amounts of food but just very, very, very healthy food," he said. "I could probably have a steak or a donut every couple of weeks, but I just haven't felt like it. When you're feeling as bad as I felt, and you go to feeling as good as I feel, the temptation to go back to doing what you were doing when you felt bad is not very great."

Penn is now also embarking on a new adventure: Exercise, which is something he wasn't doing while dropping the weight.

"Now it's really fun to exercise," he says. "The only hard part of exercise is keeping it hard enough to be hard."
