"nonsense" says weight loss expert Yvonne Bishop-Weston from Foods for Life Nutritionists.
Even the lead researcher admitted "telling people to avoid catching a virus would be useless"
"There is some evidence that suggests viruses like this could make things worse" says Yvonne "but it's certainly not the cause. Obesity is mainly due to eating too many foods that have low or virtually no practical nutritional value, the after effects of stress and sitting in front of computers all day and TVs all night"
The weight loss queen says that she has never had anyone who she couldn't help to sustainably lose weight. She points out it's not as simple as calories in and calories out, diets and exercise and there are factors such as hormone imbalances that can thwart weight loss. However "getting the body and especially the digestive system working properly and eating what you need rather than whatever you see advertised in high street windows is pretty much a failsafe strategy."
