Researchers analyzed data from children who were ages 9 to 15 in 1985 and studied the participants again 20 years later.
They found the people who did not consistently eat breakfast had waists an average of 2 inches larger than people who ate breakfast as children and as adults.
They also had higher insulin levels and higher levels of total cholesterol and "bad" LDL cholesterol.
This study is published online in the American Journal of Clinical Nutrition.
