Six years ago, David Harper considered himself relatively healthy.
The anatomy and physiology professor loved an occasional cookie, but he exercised often, cooked nutritious meals at home, and tried to stick to conventional nutrition advice: not too many calories, low amounts of fat.
But Harper started to realise that saturated fat might not be so bad, and that maybe it was the carbohydrates he ate that were causing him to pile on extra pounds and increasing inflammation.
“We’ve been telling people to eat the wrong diet for 40 years, and we’ve seen the results,” Harper told Business Insider.

Trained in mathematical biofluiddynamics, Harper teaches anatomy, physiology, and pathology at the University of the Fraser Valley in British Columbia, Canada. He said that’s part of the reason the keto diet made sense to him.
“It was the knowledge that I gained through my career teaching anatomy, physiology, and pathology that led me to the conclusion that this is absolutely right in terms of the way the human body works,” he said.
