How Many Meals Should You Eat per Day?

8. The link between breakfast and obesity

Observational studies do show that breakfast skippers are far more likely to be obese than people who eat breakfast. However, it is important to remember that correlation does not equal causation. This link could exist for many different reasons. For example, breakfast skippers might be less likely to care about their overall health and nutrition than breakfast eaters. Alternatively, breakfast skippers might lead busier lives that leave less time for breakfast and healthy meal choices. And, most importantly, there is no strong evidence that eating breakfast boosts metabolism or has any similar effects.
