Master illusionist Penn Jillette has lost 105lbs - without using any of this magic.

The 60-year-old entertainer and Wizard Wars judge dropped from 330lbs to 225lbs the old fashioned way, by making a change in his eating habits.

For four months, from December 2014 to March 2015, Jillette undertook an 'extreme low-calorie program,' he told People.com, only consuming 1,000 calories per day.

It was a visit to the doctor, which showed he had extremely high blood pressure, that motivated the father-of-two to lose weight.

'I was on six very powerful meds to bring the blood pressure down,' the former Sabrina the teenage Witch star explained.

'My doctor said I needed to get my weight down, and if I brought it down 30 or 40lbs 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."'

After losing 0.9lbs every day for four months, Jillette reached his goal weight on his birthday, March 5.

Now, to sustain the weight loss, he has begun to follow Dr. Fuhrman’s Nutritarian diet -- which means no meat, diary or eggs, no processed grains, and no added sugar or salt.

'I eat unbelievable amounts of food but just very, very, very healthy food,' admitted the magician.

Vegetables -- raw, steamed in a salad or stewed -- as well as black or brown rice, and fruits for dessert (with plain cocoa powder)is his typical daily diet.

“I could probably have a steak or a doughnut every couple of weeks, but I just haven’t felt like it,” says Jillette. “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.”

Jillette undertakes moderate exercise, using the famed seven-minute workout, along with weight lifting, juggling and ten-mile tricycle rides.
