Recent research led by Professor Tim Spector challenges the long-standing belief that breakfast is crucial for weight loss. The study, published in The BMJ, indicates that eating breakfast may not be beneficial in weight control, contrary to previous advice. The review found no solid evidence supporting the idea that consuming breakfast aids weight loss, or that skipping breakfast leads to weight gain.
Conducted by a team from Monash University in Australia, the research analysed data from 13 studies spanning the past 28 years, predominantly from the UK and the US. The studies examined the impact of regular breakfast consumption on weight change and daily energy intake. Surprisingly, the results showed that individuals who skipped breakfast consumed on average 260 more calories per day, yet were one pound lighter than breakfast eaters.
Despite the common belief that breakfast kickstarts metabolism, the researchers did not find any significant difference in metabolic rates between breakfast eaters and skippers. Additionally, skipping breakfast did not result in increased hunger later in the day or impact energy expenditure. Study co-author Professor Flavia Cicuttini cautioned against recommending breakfast for weight loss in adults, suggesting that while eating breakfast regularly may have other benefits, it may not aid in weight control.
Professor Spector noted that individuals may have varying preferences regarding meal timing that align with their unique metabolism. He emphasised the importance of personalised approaches to dieting and experimentation with skipping breakfast. The researchers highlighted the need for careful interpretation of their findings due to variations in study quality but suggested that trying out personal experiments with skipping breakfast could be beneficial as diet guidelines evolve.
