The researchers found that "the people who eat breakfast tend to have on average 260 calories a day extra and they tend to be heavier", Cicuttini said, regardless of the participants being used to having regularly breakfast or not.
However, those findings come from observational trials and critics say there may be other important differences between people who do or do not tend to start the day with a meal.
Researchers also found those skipping breakfast were also around a pound lighter on average.
To put that another way, you might as well argue that having more money and education makes you more likely to be slim - not the act of eating breakfast.
However, the new review is far from the last word on breakfast. They're saying that if you make healthy lifestyle and food choices - then eating breakfast won't have a detrimental effect on your weight. However, the effect of breakfast on weight did not differ between people with normal weight and those who were overweight.
Habitual and non-habitual breakfast eaters were studied while test subjects with a range of body weights were assessed over periods ranging from 24 hours to 16 weeks.
The theory that breakfast is the most important meal of the day may not hold true, research suggests.
The researchers also found no significant difference in metabolic rates between breakfast eaters and skippers - suggesting there is no evidence that eating breakfast may help with weight loss due to "efficient" burning of calories earlier in the day.
Coe said in an email that the "findings of this review may not fit with existing recommendations, but they reflect the current uncertainty about the relationship between eating breakfast and weight within the scientific literature".
The authors said the overall quality of the studies was low and more research is needed.
But study co-author Professor Flavia Cicuttini, of Monash University, said: 'Currently, the available evidence does not support modifying diets in adults to include the consumption of breakfast as a good strategy to lose weight'.
"The key message is that if a person likes to eat breakfast that is fine", she said.
While several studies have linked lower body weight to frequent breakfast consumption, King's College London professor Tim Spector noted such research is "flawed by bias". "Or, you might just enjoy eating breakfast foods".
Cicuttini told CNN the belief breakfast helps people better metabolize food and leaves them less hungry throughout the day stems from earlierobservational studies, adding that it was possible that people who ate breakfast had other healthy habits, like exercising.
'While waiting for guidelines to change, no harm can be done in trying out your own personal experiments in skipping breakfast'.
