Meal Timing
How often you eat only matters alongside when: skipping breakfast alone is metabolically neutral, skipping it AND eating late is not.

First: eating more often doesn't speed metabolism

Stop 1/6

先说清 · 吃得勤不会加速代谢

You've probably heard that small frequent meals keep your metabolism burning like a stoked fire. Bottom line first: it's a misunderstanding. What decides how much energy you burn in a day is your total intake and how active your body is, and it has almost nothing to do with whether you split that food into 3 meals or 6 (Bellisle 1997).

Why do so many people believe it? Because each meal costs a little energy to digest (the thermic effect of food), and you really do feel a bit 'warmed up' after eating. But here's the key: that cost scales with how much you eat, not with how many times you eat. Split the same food into 6 small meals and the little thermic bumps add up to exactly the same as 3 big meals (Schoenfeld 2015's meta-analysis confirms meal frequency is unrelated to weight loss or body composition).

In other words, eating more often doesn't burn extra energy out of thin air, it just breaks the same bill into more line items.

What this means for you: don't force yourself to eat every 2 hours to 'rev your metabolism.' For most people, 3 meals with no snacking in between is simpler, makes total intake easier to control, and keeps you from thinking about the next bite all day. Meal frequency is a personal preference, not a metabolic switch.
