Breakfast Eaters Less Likely to Be Overweight
A study from Taiwan published in April indicates that people who eat breakfast are more likely to be at a healthy weight. This reinforces most of the previous findings on the subject.
One theory as to why is that skipping breakfast leads to eating more calories later in the day, but that doesn’t seem to be the case as breakfast skippers have been shown in previous research to eat the same or less calories. It seems likely to me that skipping breakfast slows down your metabolism.
It also could be that skipping breakfast doesn’t cause the weight gain, but is merely associated with something else that causes it. To adjust for this possibility, the researchers controlled for age, gender, marital status, educational level, income, smoking status, alcohol consumption, and exercise, and so differences in these variables between breakfast skippers and eaters should not account for the differences in body weight.
