Is Breakfast Really the Most Important Meal of the Day?

Highlights
•
Breakfast is not metabolically essential — the dogma comes from cereal industry-funded research
Betts: randomized controlled trials show that skipping breakfast does not slow metabolism, cause weight gain, or impair cognitive function in adults. The 'breakfast is the most important meal' claim was largely promoted by cereal companies.•
When you break your fast matters more than whether you eat breakfast
Betts: regardless of whether you call it 'breakfast,' the timing of your first meal should align with your circadian rhythm. Eating within 2-3 hours of waking leverages peak insulin sensitivity, while delaying until afternoon may impair glucose handling.Was this useful?
