The Claim: Breakfast is the most important meal of the day and kickstarts your metabolism. If you skip breakfast you’ll overeat at the end of the day and you won’t perform as well at work/school.
Eating breakfast has no special effect on your metabolism or metabolic rate as it were. If you like to eat breakfast then by all means go ahead, but don’t expect it to help with your ability to burn calories.
There is some persistent claim that breakfast can also help with cognitive function but this research was only shown to have an effect in children. It may very well be that growing children might do better in school if they get something to eat in the morning simply because it keeps them happy and more attentive in class. Whatever the case may be it is clear that there is no effect of breakfast on adults.
So, eat breakfast if you like, but be aware that it’s not going to have a special effect on your ability to burn fat or get work done.
