Breakfast is the most important meal of the day for good reason. You are breaking the fast your body went through the night and fuelling it with essential nutrients to get your day started. While some enjoy a hearty breakfast in the morning, some may skip their breakfast due to waking up late or having no time to rush to work. Amy S. Margulies, RD, CDCES, LDN, NBC-HWC, says, “The morning is a busy time! When you are trying to get yourself to work, even when working from home, or taking your kids to daycare or school, time for you to eat breakfast is not going to naturally occur. It takes conscious effort to make sure you provide yourself with the time to sit down at a table, in a chair, and enjoy at least 15 minutes to consume a well-balanced breakfast.”

Elizabeth Quinn, CNS, FMCHC, says, “When you skip breakfast, you are in a calorie deficit for the rest of the day. Your body will get that energy one way or another. The hungrier you get, the less willpower you will have. Now you will start to think of all those foods that you crave.”

Skipping breakfast peps up the craving for sugary and fatty foods. Plus, since your hunger pangs will quite be intense, you end up gorging down whatever you come across during the day.

Which meal is best to skip?
