Eat breakfast like a king, lunch like a prince, and dinner like a pauper…this is advice of which anthroposophical doctors have long been aware.
Digestive forces are strongest earlier in the day.
Are you considering intermittent fasting? For most people, eating breakfast and lunch, and then fasting the rest of the day is the best overall option.
(If you have an eating disorder, think of the structure of your meals and avoid the concept of intermittent fasting.)
Looking to improve sleep quality? Eat breakfast!
Trying to improve your cardiovascular risk and lower your blood pressure? This is the ticket!
Needing to improve blood sugar control? Eating your heavier proteins and fats earlier in the day will help them stabilize.
Another caveat: avoiding sweet tastes until the afternoon hours improves energy and cognitive powers, and can eliminate that annoying after-lunch grogginess.
