A supermarket has introduced a range of ready-made meal that can deliver a 10lb weight loss in four weeks - without any exercise, say experts.
Researchers, who tested the Simply Fuller Longer regime from Marks and Spencer, have found that it actually deliver those results, reports the Daily Mail.
AdvertisementThe diet, which was tested on 45 overweight volunteers who were restricted to 1,000 calories a day, reduced the average waist measurement by 1.6 inches and also improved body fat, blood pressure and cholesterol levels.
Devised using principles developed by experts at the Rowett Research Institute, Aberdeen, the range is high in protein, which was found to make the volunteers in the trial feel full, eliminating the need to top up on snacks.
According to M and S, the food is particularly successful with men because it includes substantial main meals, rather than salads and soups.
For example, there is a 400g portion of roasted beef meatballs and spaghetti with spiced tomato and pepper sauce and a 420g beef and red wine casserole.
"We knew from studies that diets higher in protein are better for weight loss. It's really encouraging to see that this has all been proven by our research," M and S nutritionist Claire Hughes said.
The retail chain has been promoting the range through TV commercials featuring actress Caroline Quentin.
