Musk decided to go on the diet drug Ozempic and follow an intermittent fasting diet, eating only one meal per day. That meal, in his case, was a late breakfast, and his version of the diet allowed him to gorge as he pleased for that. At 11 a.m. on Wednesday, he went to the Palo Alto Creamery, a retro-hip diner, and ordered a bacon-cheese barbecue burger with sweet potato fries and an Oreo and a cookie-dough ice-cream milkshake. X helped by eating some of the fries.
