The notion that skipping breakfast contributes to weight gain doesn’t mean that eating breakfast can help you lose weight, a research review from Monash University in Melbourne in Australia suggests.
Researchers examined data from 13 studies in which some participants ate breakfast and others skipped it. The people who ate breakfast consumed more calories and weighed more than individuals who skipped this morning meal.
Breakfast eaters ate an average of 260 calories more a day and weighed an average of 0.44 kilogram (about 1 pound) more than breakfast avoiders.
According to the researchers, “A calorie is a calorie, whatever time you eat it, and people shouldn’t eat if they are not hungry.”
While some previous research has suggested that eating breakfast increases the likelihood of maintaining a healthy weight, many of the studies in the new review were not randomized controlled trials designed to prove whether breakfast directly causes weight loss or prevents weight gain.
There is also the possibility that people who eat breakfast have a healthier weight because they’re different from those who skip it, with perhaps healthier overall eating habits or more consistent exercise routines.
No difference between eating or skipping breakfast and weight, metabolism, hunger
Researchers examined data from clinical trials done mainly in the U.S. and the UK over the past three decades that looked at the effect of eating breakfast on weight and calorie intake.
There was no meaningful difference in the connection between breakfast consumption and body weight or calorie intake based on how much individual participants weighed. Results were similar for people at a healthy weight and for individuals who were overweight.
Some studies looked at whether breakfast influenced metabolism (i.e., how many calories people burned). But researchers didn’t find meaningful differences based on whether or not participants had breakfast.
Dieters are sometimes told skipping breakfast will make them hungrier and increase their propensity to overeat later in the day. But the analysis didn’t find a difference in hunger levels based on whether or not participants ate a morning meal.
One limitation of the analysis is that the smaller studies included were all too brief to see whether or how eating breakfast might affect long-term weight control or calorie consumption.
Still, the lower total calorie intake associated with skipping breakfast suggests this approach may work for some dieters. When people skipped breakfast, they did eat more later in the day, but not enough to compensate for the extra calories they had not consumed earlier.
These new findings suggest, but don’t prove, that breakfast skipping may help some people lose weight.”
The types of foods people eat may matter as much, if not more, than the total calories they consume or exactly when they have their first meal of the day, say experts.
People are unique and may benefit from different amounts of carbohydrates or fats depending on their genes, microbiome and metabolism.
