Highly interesting. I'm doing the Adrenal Fatigue protocol, which emphasizes a hearty breakfast within an hour of waking. This gives me a small lunch and a very light dinner, eaten to appetite.

If I try to stretch out the times, I get a headache; my signal that my body is struggling to increase cortisol according to demand. Which makes me think the warnings about IF being a strain on women's adrenals might be true.

I also upped carbs a bit, but mine were low before; basically adding more berries, yogurt, and nuts. Still no snacking.

Not to disparage anything, merely contrasting. Because it would make sense that different disease states would require different approaches, and skipping lunch might be metabolically different from skipping breakfast.
