In this segment, JJ Virgin explains that circadian rhythm governs our health more than what we eat. She outlines a sequence where time influences hormones, which in turn affect mitochondrial metabolism. Emphasizing that we are driven by the sun, she advises aligning eating patterns with daylight—specifically, consuming the largest meal around noon when light is brightest. She also stresses the importance of morning light exposure to boost cortisol levels and set up proper melatonin production for nighttime, framing light management as a foundational step for hormonal balance and metabolic health.

When I started to get into circadian rhythm, I realized circadian rhythm trumps everything else. It's not just what you are eating, it's when you are eating, and it's when you're doing everything else. The sequence is time, hormones, and the mitochondria or metabolism. We are run by the sun. Look at the light. So whenever the light is brightest is when we should eat the most. That would be around the noontime hour, like a full-on lunch. I notice when I'm in healthy rhythm, I'm just naturally hungry great when I actually should be. When we get that morning light, we help with our cortisol levels, and then we help to set the stage for healthy melatonin production and secretion at night. Get your light right.
