David Harper, a cancer researcher and kinesiologist, has been on a high-fat ketogenic diet since 2013.
He says the sugar-free eating plan has helped him slim down even though he eats a lot of fat.
Harper has written a new book, “Biodiet,” about how to follow the trendy keto diet in a healthy, science-backed way.
One of the problems with modern “Western” diets, he says, is that they tend to promote inflammation, obesity, and disease by relying too much on sugar and other carbohydrates.

Start the day off with a piece of toast, a bit of margarine and jam, and a glass of fresh orange juice? Definitely not, says cancer researcher David Harper.
The kinesiology professor hasn’t eaten toast in more than six years: He started following a high-fat, low-carb ketogenic diet strategy in 2013, and said he’s never looked back.
Harper said he and his wife, Dale Drewery, both rely on fat to power them through the day.
“I eat full-fat cream in everything,” Harper told Business Insider, adding that he consumes lots of nuts and seeds, green beans, “organ meats” like liver, and up to a dozen eggs each week.
The keto diet Harper follows is designed to force the body into a state of ketosis, in which it uses fat for energy and produces ketones, instead of relying on carbohydrates and turning them into glucose. (It’s essentially the same switch our systems make when starving.)
Harper and Drewery have written a new how-to book about going keto, called “Biodiet,” which was released in May. In it, the couple suggest that our modern diets are formulated around too much sugar and too few veggies.
Harper refers to carb-heavy diets as a modern “axis of illness,” a reference to the term “axis of evil” that President George W. Bush used to describe Iran, Iraq, and North Korea. When it comes to our health, Harper insists, the “three common enemies” we’re at war with are obesity, insulin resistance, and inflammation.
“At the core of the axis of illness is a weapon of mass destruction,” Harper writes. “The high-carbohydrate diet most of us have been eating our entire lives.”
According to Harper, this carb-loaded eating regimen promotes a vicious cycle of disease and disability in our bodies.
“As these conditions worsen, they feed upon one another: obesity contributes to insulin resistance, which in turn worsens obesity; inflammation aggravates obesity, promoting more inflammation; insulin resistance causes more inflammation, which worsens insulin resistance,” he writes in the book.
The ‘axis of illness’ on our plates
On a well formulated keto diet, the idea is that no more than 5% of a person’s daily calories come from carbs, while around 80% is made up of fat. Harper said he and Drewery will often split a fat-marbled steak for dinner, or pair a bit of chicken (fatty skin left on) with low-carb shirataki noodles made from Japanese yams.
