Days before Pete Katz’s visits to his primary-care physician, he would go on a diet. It was his vain attempt to nudge his health markers in the right direction.

But the short-lived change had little effect on an increasingly grim reality.

“Pete was in a common situation for many patients in that his weight was not ideal. And early on he did not have significant health problems from that,” said Dr. J. Harry Isaacson, Katz’s physician of roughly 15 years. Isaacson is also assistant dean for clinical education at the Cleveland Clinic Lerner College of Medicine in Ohio.

“Many people end up crossing a threshold … where they start to accumulate different health problems from their weight.”

For Katz, that threshold was a Type 2 diabetes diagnosis at the age of 41.

“That’s a whole different ball game,” Isaacson said.

To treat the disease, the doctor prescribed oral medication. After three years, it wasn’t enough. So Isaacson prescribed an injectable drug. This was in addition to Katz’s treatments for anxiety and high blood pressure.

Injecting himself with medicine and constantly monitoring his insulin put enough fear into Katz that he finally heeded the advice Isaacson had long been giving him: Change your diet and start exercising.

Before then, Katz had tried multiple diets and exercise programs over the years; nothing stuck. This time, he started following the Paleo Diet. About a month later — in November 2012 — he had his first class at CrossFit Painesville in Ohio.

Six months after that, Katz was able to discontinue all of his medications.

“He’s basically cured his diabetes with his attention to lifestyle,” Isaacson said.

He added: “For someone to go off medications and control it, it’s quite uncommon, actually.”

The doctor called Katz’s ability to affect his own health “remarkable.”

“The big message is that if you’re faced with a health problem like this, you have an opportunity as a patient to … have a significant impact.”

Today, Katz is working toward 15 percent body fat and is a coach at CrossFit Painesville.

Julie Foucher, a former CrossFit Games athlete and a medical student at the Lerner College, has known Katz for three years and attributed his success to the accountability he found at his affiliate.

“He has tried a lot of other programs,” she said. “One of the big reasons he was successful was the community.”

Today, 48-year-old Katz looks forward to his visits with Isaacson.

“It is fun to take those tests now.”

The last time he saw the doctor was June 4, 2015. All of his health markers were considerably improved since they were at their worst.

“It works. It’s good medicine,” Katz said.

When asked if he was referring specifically to diet or CrossFit, he replied quickly.

“Both. Like I said, it’s hard to say which it is. But I wouldn’t stop either one ever.”
