what is huberman saying about eating in the morning

Huberman doesn’t say everyone needs to eat breakfast: eating early can boost morning alertness, but he often waits until around 11 a.m. or noon. 1 2

• Eating early: Food in the morning can increase metabolism and body temperature, which may make you more alert. It also helps set the body’s food-related circadian timing. 1
• Waiting to eat: He says the choice is personal; he commonly delays his first meal until about 11 a.m. or noon, though he sometimes eats breakfast. 3 4
• Large breakfasts: A very large meal may make you sleepy afterward, so meal size matters if you eat early. 5

He presents early eating as an option for alertness, not a requirement.
