Over January, we are bombarded with adverts for 'healthy' food, as retailers look to cash in on the post-Christmas diet market. M&S are pushing their Simply Fuller Longer range, which offers protein-rich ready meals and snacks.
The Rowett Institute of Nutrition and Health conducted an independent trial which looked at weight, hunger, fullness and other measurements of health such as blood pressure.
The M&S-commissioned research found people who ate their Simply Fuller Longer range averaged a 4.73Kg (10.4lbs) weight loss over four weeks. All 45 volunteers lost weight over the four week period (5% of body weight).
The average calorie intake was reduced to 40% by the end of the study and an eight-week follow up with 12 case studies also got great results - an impressive 7% of body weight and average weight loss of 6.5kg.
Meals in the range include Japanese Char-grilled Chicken with Rice Noodle, Miso & Mushroom Dressing (£3.99) or Middle Eastern Style Chicken with Aromatic Vegetable Pilaff & Pomegranate Molasses Dressing (£3.99).
M&S Nutritionist, Claire Hughes, said: “We knew from studies that diets higher in protein are better for weight loss as protein keeps you feeling full and not reaching for snacks that can often derail the best diet plans.”
