The 800-calorie diet that really works

DRAMATIC weight loss through strict low-calorie diets can be more effective at keeping weight off than other types of weight control, a study found.

Oxford University researchers found those who ate no more than 810 calories a day through soups, shakes and bars had lost more than three times as much as other dieters a year later.

Dieters lost on average 1st 9lb (10.7kg), just over a stone more than other dieters who had followed an eating plan recommended by their GP.

They also showed greater reductions in their risk of developing heart disease,

stroke and diabetes. The findings appear to contradict previous suggestions that people who lose weight quickly are prone to piling it back on.

The latest trial involved 278 adults in Oxfordshire with a BMI over 30, making them clinically obese. Participants were either offered a referral to a lowenergy total diet replacement programme for 24 weeks or enrolled into their GP practice’s weight management programme, which included advice and support from a nurse.

Those on the diet replacement programme were asked to reduce their intake to 810 calories a day by switching all food with specially formulated soups, shakes and bars in addition to milk, water and fibre supplements.

Diet replacement products were offered for eight weeks, followed by a re-introduction of conventional food over four weeks. From 12 to 24 weeks, they were encouraged to use one product a day to replace a usual meal.

Almost half – 45% – of participants on the low energy programme achieved a weight loss of 10% or more.
