A trial conducted at the The Boden Institute of Obesity, Nutrition, Exercise and Eating Disorders in Australia has concluded that obese women who lose weight are "three times more likely to fall pregnant".

Dr Kyra Sim of the University of Syndney said: "A weight-loss intervention, incorporating dietary, exercise and behavioural components, is associated with significantly better pregnancy and economic outcomes in a group of obese women undergoing assisted reproductive technology."

The trial involved randomly assigning 49 obese women undergoing fertility treatment to a strict diet for 12 weeks and found that women on the diet lost more than 14lbs compared to just under 4lbs for those not.

Dr Sim is presenting the findings at the European Congress on Obesity in Lyon, France and suggested women who dieted needed fewer cycles of IVF to fall pregnant, saving on average £5,865 per pregnancy.

The NHS will not generally not fund IVF treatment if the woman is overweight or obese as it is known that this makes fertility treatment less successful and riskier, however women are still able to pay privately.
