Andrew Huberman consumes a high-protein, moderate-fat, low-carb meal at lunch to favor dopamine, acetylcholine, and epinephrine production for alertness.

“I eat a relatively high protein and moderate fat, zero-carb or low-carb meal at lunch and in the afternoon to stay alert. Because those foods tend to favor dopamine production, acetylcholine production, epinephrine production, and alertness.”

“And then as evening comes around and I'm concerned about sleep and a good night's sleep-- not concerned in an anxious way, but I want to get a good night's sleep-- I will ingest foods that promote serotonin release because they contain a lot of tryptophan.”

“I've talked before about my preferred way of eating is to go low or no carbohydrate throughout the day for alertness, to get that adrenaline release and the focus that goes with it, et cetera, the ability to think and move and do all the things I need to do during the day. Then I eat carbohydrates at night because it facilitates the transition to sleep. That's what works for me.”
