Research has disputed this, however. From a public health perspective, skipping breakfast has had its critics, too. Breakfast, they say, is the most important meal of the day.

But the evidence to support this largely comes from epidemiological findings that populations who skip breakfast are more likely to be overweight. Indeed, though the correlation exists on paper, I think the data overlooks the fact that the people skipping breakfast could be doing so to try and lose weight, rather than it being the cause of being overweight, and that there is a larger nutritional mishap taking place to cause this statistic. Slightly less commonly adopted, skipping dinner is behaviourally much harder than breakfast.

Culturally, we have become accustomed to a large energy load in the evening. But in spite of relative difficulty, herein lies one of the biggest cases for choosing it as the meal to miss. Glucose tolerance tests are often done by giving people a meal in the morning because you have to do it in a fasted state.

If you do a glucose tolerance test at dinner, you get a more elongated glucose response because it takes longer to clear that lipid from the meal.

This typically leads to a lower meal tolerance in the evening, taking you longer to clear the incoming fuel.
