Many of us grew up being told breakfast is the most important meal of the day. "Well the evidence now says that's not the case".
The studies included people who regularly eat breakfast and non-breakfast eaters.
So a team from Monash University in Melbourne analysed the effect of regularly eating breakfast on weight change and daily energy intake, based on evidence from 13 randomised controlled trials, mainly in the USA and United Kingdom, from the last 28 years.
People who ate breakfast ended up eating about 260 calories more a day, the review found. People who skipped breakfast were about one pound lighter than those who ate breakfast.
They found that breakfast eaters consumed more calories overall and breakfast skippers did not have a greater appetite in the afternoon.

The new research comes just after Hollywood personal trainer and physical therapist David Higgins told INSIDER he believes breakfast is overrated. But food can also be a joy, and denying ourselves meals can quickly descend into disordered eating and a negative relationship with food.
NHS advice warns: "Some people skip breakfast because they think it will help them lose weight".
