The report found that middle-aged men are motivated to lose weight once they perceive they have a health problem they want to tackle.
They welcome the moral support of other men in weight-loss programmes and also prefer the use of simple "business-like" language and humour used sensitively.
Researchers from the universities of Aberdeen, Bournemouth and Stirling analysed evidence from around the world involving more than 15,000 men gathered from weight loss trials and studies.
They have suggested that if weight-loss programmes were specifically designed for men they might be more effective at helping them lose weight, which could reduce the risk of health problems like diabetes.
Chief investigator Professor Alison Avenell, a clinician from the Health Services Research Unit at the University of Aberdeen, said: "More men than women are overweight or obese in the UK, but men are less likely to see their weight as a problem and engage with weight-loss services."
