Eating behaviours describe how people eat rather than what they eat. We believe that some current, common eating behaviours are part of the problem causing an increase in obesity levels in the UK and elsewhere. We put some questions in to the ALSPAC questionnaire for participants aged 25 years that asked about how fast they ate their meals, with whom and in front of what items if any of technology (such as computers, TV etc.). We will examine this information to see if any such behaviours tend towards increased body mass index in the cohort. This information may add to our clinical advice when counselling people with excess weight how to lose or maintain weight loss.
