Andrew Huberman fasts until 11 AM or 12 PM, then consumes a low-carb, keto-ish lunch and dinner with carbohydrates to aid sleep.

“The way I eat is that early in the day I fast, and then sometime around noon I eat my first meal, and that meal is always low carbohydrate, and then throughout the day, I maintain a low carbohydrate diet. The fasting and low carbohydrate diet during the daytime optimizes alertness and wakefulness, I want to be awake and be able to work.”

“For me, what works is to fast in the early part of the day and to eat low carb and keto-ish throughout the day. That's for alertness and attention. So I can work and focus and I don't feel sluggish or brain fog. And then at night and in the evening is when I tend to eat my carbohydrates to aid the transition to sleep.”

“As I mentioned, I eat my first meal sometime around noon plus or minus an hour for the reasons we've discussed. The volume of food is also important. ... So for lunch, I do emphasize slightly lower carbohydrate or low carbohydrate intake for the simple reason that adrenaline and dopamine and their associated neuromodulators are going to support alertness.”

“So typically I'll fast until about noon or one and then my lunch consists of a small piece of steak or chicken and some salad and then I tend to eat my carbohydrates in the evening before I go to sleep.”

“I tend to fast in the early part of the day, I tend to eat kind of low carbish through the middle of the day. And then in the evening I eat carbohydrates. That's what works best for me, and allows me to feel alert all day long, and to sleep really well at night.”

“What works best for me is to fast until about 11:00 a.m. or noon most days, and then to eat a low carbohydrate lunch, a low carbohydrate snack in the afternoon, and in the evening is when I eat my starches. That's what allows me to be alert throughout the day for work, for exercise and so forth, and then to sleep really well at night.”

“Which for me means fasting until about 11:00 am or noon most days, then I eat low carb during the day. So I'll have some meat or fish or chicken and some salad that's what works for me, and in the afternoon, I remain on a more or less low carb-ish diet, and then in the evening, I eat pastas and things primarily and I throttle back on the protein and that's what allows me to fall asleep at night.”

“So for me, that means fasting until about 11:00 AM or 12 noon most days. And then my lunch is typically a low carb, ketoish lunch, maybe a small piece of grass-fed meat, some salad, something of that sort. And then in the afternoon I might have a snack that's also ketoish. And then at night is when I eat my carbohydrates, which for me helps me with the transition to sleep and allows me to get great deep sleep.”

“I typically eat my first meal right around uh midday um whether or not I've exercised or not in general I rely on a low carbohydrate meal I'll eat meat or salad or some variation of that and um nuts and fats and things like that because of the choline content for Focus”
