"I literally just couldn't get to the gym as often. I just kind of put on a few kilos," the astrophysicist - who has a doctorate in philosophy - said. "Leading up to submitting the PhD dissertation there was a lot of work obviously. I was running low on time [to work out]," Matt continued.
Matt revealed that he follows an intermittent fasting regimen - which means he consumes all his daily food intake during a small four to six-hour window. "So I usually only really have coffees, I don't do breakfast. Sometimes I'll skip lunch," he recently told an Australian publication.
"I eat in a smaller window, sometimes only 4-6 hours in the evening. They're a lot of proteins, lean meats, salads, yoghurts."
