Prior research suggests that breakfast eaters may be healthier than people who skip breakfast, and a study in the American Journal of Clinical Nutrition suggests a nutritious breakfast may be especially good for your heart.

While prior research has shown that skipping breakfast may lower a person’s energy level and increase the risk of weight gain, less is known about the effects of skipping breakfast on other body organs and functions.

Twenty years later, one third of the original participants filled out a meal frequency questionnaire, had their waist size measured, and had blood levels of triglycerides, total and LDL (“bad”) cholesterol, and fasting insulin (insulin levels after no food has been eaten overnight) checked. Participants were then classified into four groups:
Results showed that people who skipped breakfast in both childhood and adulthood had a larger waist size and total cholesterol and LDL cholesterol levels compared with people who ate breakfast in both childhood and adulthood. They also had higher fasting insulin levels, which indicates they have insulin resistance, a risk factor for diabetes and heart disease.
Breakfast skippers also tended to be single, have a lower education level, and were more likely to smoke, watch TV, get less physical activity, and have a less healthy diet compared with breakfast eaters.
