People eating prunes as part of a weight loss diet lost 50% more off their waistlines, research has revealed.
Prunes also contributed to them losing 33% more weight than those who did not eat them.
Eating prunes made people feel more full, the researchers found.
The study involved 100 overweight and obese people.
Half ate around 15 or more prunes each day as part of a healthy lifestyle diet.
The other group were simply given advice about healthy snacks.
The results showed that prune-eaters lost an average of 4.4 pounds in weight compared to just 3.3 pounds in the other group.
Those eating prunes also shed an inch from their waists in comparison to only two-thirds of an inch in the other group.
Dr Jo Harrold, who led the research, said:
“These are the first data to demonstrate both weight loss and no negative side effects when consuming prunes as part of a weight management diet.
Indeed in the long term they may be beneficial to dieters by tackling hunger and satisfying appetite; a major challenge when you are trying to maintain weight loss.”
Professor Jason Halford, an expert on eating behaviours, said:
“Maintaining a healthy diet is challenging.
Along with fresh fruit and vegetables, dried fruit can provide a useful and convenient addition to the diet, especially as controlling appetite during dieting can be tough.”
