Summary

What if the "when" of your eating matters more than the "what"? I’ve talked about sleep for years, but this conversation with Dr. Deanna Minich made me realize sleep is just the tip of the circadian iceberg. She showed me how light, timing, hormones, and mitochondrial health are all orchestrated by our internal clock — and how modern life is throwing it completely off. If we truly want to age powerfully, especially through perimenopause and menopause, we have to get our light right and reclaim our rhythm. What you’ll learn: (00:00) Why circadian rhythm trumps diet and exercise in controlling metabolism. (06:21) How artificial light at night disrupts melatonin and accelerates aging. (18:17) Why melatonin is far more than a sleep hormone and acts as a powerful antioxidant. (27:17) How circadian disruption worsens perimenopause and menopause symptoms. (41:42) What the “aging gates” at 44 and 60 reveal about metabolic decline. (49:07) Why meal timing matters more than calorie counting. (54:24) The ideal eating window based on natural light exposure. (59:48) The single most powerful step to reset your body clock this week. Love the podcast?

0:05.1	but the history of the sports is more odd and interesting than you might realize. Like archaeologists

1:01.3	It's not just what you are eating, it's when you are eating, and it's when you're doing
1:06.5	everything else.
1:07.6	The sequence is time, hormones, and the mitochondria or metabolism. We are run by the sun.
1:15.4	Look at the light. So whenever the light is brightest is when we should eat the most. That would be
1:19.9	around the noontime hour, like a full-on lunch. I notice when I'm in healthy rhythm, I'm just
1:25.6	naturally hungry when I actually should be.
1:28.1	When we get that morning light,
