However, the studies have also been criticised. Catherine Collins of St George's Hospital in London stated that a pupil in the Merton study had "suffered sleep problems and her weight dropped as a result of the advice [Mr Holford] gave." The study has been criticised as being unscientific, with results "cherry-picked" and the effects merely a "placebo". Holford and the foundation reject some of these allegations. Holford claims that the pupil in the Merton study has since regained the lost weight, which he puts down to a reduction in her gluten intake, after tests revealed she was "gluten sensitive". He states that her overall behaviour and health have improved during the study.Holford, Patrick.
