Breakfast: the Most Important Meal of the Day?

Boost metabolism. Improve blood sugar control. Enhance weight loss. Decrease risk of Type 2 Diabetes. These are all common claims made about eating breakfast. Despite extensive research to answer the question ‘Is breakfast the most important meal of the day?’, the research remains inconclusive.

Weight Management & Breakfast

While research has demonstrated that those who eat breakfast are less likely to be overweight or more likely to maintain weight loss, the studies are cross-sectional in nature and do not prove cause and effect. Therefore, there could be other characteristics of early morning eaters that result in maintaining a healthy weight. For example, those who eat breakfast may be more likely to exercise, in which case exercise, rather than their morning nutrition, would be the reason for healthy weight maintenance. 

In addition, researchers have hypothesized that skipping the first meal leads to overeating or choosing low quality foods later in the day, which can result in weight gain (or prevent weight loss); however, research findings are inconsistent. 

Blood Sugar and Metabolism

Beyond weight management, you may hear that skipping breakfast negatively impacts blood sugar control or that eating breakfast can boost your metabolism. Again, research findings are weak. For example, one study demonstrated improved blood sugar control in those who ate breakfast compared to those who skipped; however, the study was conducted in 10 young males and did not demonstrate any differences in metabolism or body composition between the two groups. 

Energy and Concentration

Glucose is the primary fuel source for your brain; however, your body has limited stored supplies. As such, after an overnight fast, your supply of glucose for your brain may be low, and you may start to feel sluggish throughout the morning if you don’t eat early. Some studies have demonstrated improved energy and ability to concentrate in those who eat breakfast compared to those who don’t. However, this varies across individuals, and some people claim to have more energy in the morning without this meal. 

Vitamins and Minerals

If you eat breakfast, you may be more likely to meet the recommended daily intake of vitamins and minerals. Meeting recommendations can improve health; however, it is still possible to meet dietary recommendations without eating a morning meal.  

Bottom Line on Breakfast

In conclusion, a healthy diet is not just about whether or not you eat breakfast. If you aren’t hungry in the morning and your energy levels aren’t negatively impacted by skipping your morning meal, then aim to make up for nutrients you missed with lunch, dinner and healthy snacks throughout the day. 

However, if you aren’t skipping your morning meal because of lack of hunger, but because of time, energy or lack of ideas, check out our Overnight Oats recipe for something nutritious that you can prepare in advance! 

Lastly, if you are eating a morning meal but are still experiencing lack of energy in the morning, make sure your choices are well-balanced by incorporating whole grains, protein and healthy fat. For more ideas or questions, don’t hesitate to reach out to Nicole at
