Self monitoring is a proven
way to lose weight
Many doctors and dietitians ask patients to keep a food diary as the simple act of monitoring what you eat has been proven to change behaviour. Here is just some of the evidence:
Nutracheck research presented at Xl International Conference on Obesity conference in Stockholm in July.
Data from our own Nutracheck study was presented by Dr Fiona Johnson, Research Psychologist, UCL, London.

The research found that the longer people kept a food diary for, the more weight they lost:
Also the more food diaries entries made, the more weight was lost:

Researchers at the World Health Organisation Collaborating Centre for Obesity Prevention, at Deakin University in Victoria, Australia, said that the findings would be reflected in other industrialised countries such as Britain.
