In the dieting (excuse me, biohacking) trend known as intermittent fasting, people compress their calories into a limited window of hours. But that's not what Big Meal is at all. It's not a diet. I snack whenever I feel like it - Triscuits with slices of pepper jack, leftover hummus from the Turkish takeout place that sometimes provides Big Meal, a glob of smooth peanut butter on a spoon. The phrase started as a joke about my inability to explain to a friend why I was making risotto in the middle of the afternoon, or why I didn't have an answer to "What's for dinner?" at 6 p.m. beyond "Uh, well, I ate a giant burrito at 11 a.m. and grazed all afternoon, so I think I'm done for the day." Now I simply say, "It's time for Big Meal," or "I already had Big Meal."
