Skipping breakfast isn't unceasinglythe healthiesthabit, and it has been relatedto weight gain, according to a researchin the American Journal of Epidemiology in 2003. The study authors looked at the dietary patterns of around 500 subjects over the course of a year, thatpick the diet trends linked to weight gain. They found that people who regularly skip breakfast had a higher risk of obesity. A second study, that was explainedin the Journal of Rural Medicine in 2014, found similar results and even noted that skipping breakfast was more fullylinked to weight gain than eating before bed. People who skip breakfast had a higher risk of obesity, that doesn't necessarily mean skipping breakfast is the reason they gained weight. It could be that people who skip breakfast tend to have other lifestyle habits that cause obesity -- for example, hitting the drive-through or eating packaged convenience foods.
