Richard James Adair, Jr., had always been heavy. Now a 42-year-old software architect from Red Lion, Pennsylvania, he remembers going to Sears to shop for school clothes, heading straight to the husky section. Without any conscious effort to change his diet—“I would eat anything and everything,” he says—and a profession that had him sitting at a desk, over the years his weight kept creeping up.

He crested 40 at over 300 pounds; working from home helped him gain more. “I started to get to the point that I was taking a break to catch my breath going upstairs for the night,” he says. “I couldn't even now the lawn without multiple breaks.”

It took his wife to inspire him—after limited success with diets, she tried keto and found it worked. Adair, then at 344 pounds, began dieting on New Year’s Day, 2019. He no longer had his gallbladder, so he couldn‘t go full keto, but he cut out as many carbs as he could while still eating as much as he wanted. (His current goal is 20 carbs a day, on a diet of 2,000 calories daily.)
