My Day Doesn't Start With Breakfast. It Starts With the First Meal.

My Day Doesn't Start With Breakfast. It Starts With the First Meal.

I rarely eat breakfast — and it has nothing to do with eating less, nothing to do with discipline. More precisely: my day doesn't begin with breakfast, it begins with the first meal, and that usually lands near midday.

The early hours are when I'm clearest and sharpest. As a founder, I won't spend them on digestion. Empty, I'm quieter and more focused; the thinking runs in one continuous line. I don't drink coffee either — plenty of people boot up on it; I'd rather let the body wake on its own rhythm. So my mornings are for work, not food. The first meal is less a day's opening ration than a system formally coming online.

There's real physiology under this. Circadian rhythm doesn't only govern sleep; it governs metabolism. The body's ability to handle the same meal shifts across the day, and the research here is unusually clean: glucose tolerance is highest in the morning, with insulin sensitivity and first-phase insulin release both stronger earlier; the same meal can move blood sugar up to twice as much in the evening as in the morning. The gap is almost comic in scale — someone with perfectly normal glucose handling in the morning can look, by night, metabolically like someone prediabetic. Compressing eating into a relatively contained daytime window (intermittent fasting, or time-restricted eating) is, at bottom, lining the act of eating up with the body's own rhythm instead of fighting it.

I want to be clear: for me, fasting was never a way to eat less. It's a way to keep rhythm. The fasted stretch is white space — time the body doesn't spend processing food and can spend on other things: repair, clearing, steadying. And when I do eat, I want the meal generous, complete, worth it. It's a structure, not a restraint.

Because there's only one fairly concentrated window, I'm almost fussy about what the first meal is. It should open the system gently, not yank it up and drop it — so it tends to start with protein and fat rather than sugar. Cold kefir straight from the fridge with a few boiled eggs and a handful of berries; or a piece of barely-cooked fish, a pile of greens, good olive oil. I care about the texture of the first bite — kefir's thick little sourness, the give of a yolk, the softness of fish. It makes powering on both steady and a pleasure.

I know calling a meal a "system coming online" is deeply nerdy. I am deeply nerdy. But the way I feed myself for the first time each day sets the clarity of many hours after it. That meal, I never leave to chance.

Framing here is metabolic rhythm and deep-work clarity, not weight.
