This intervention examined the efficacy of a six-week online weight loss programme. Students and staff of a third level institution (n=183) were recruited to the programme which provided individualised dietary advice for weight loss. Eighty-five participants (mean age 29.7 years, mean BMI 28.9kg/m2, 33% male) met the minimum inclusion criterion of logging on to the study website at least twice. All participants who completed the full six-week programme lost weight (n=31), with significant reductions in mean weight (2.8kg), BMI (0.9kg/m2) and waist circumference (4.1cm) observed between the start and end of the programme (all P5% of their bodyweight, with reductions in biscuit and alcohol consumption being most predictive of weight loss. These findings suggest that individualised online dietary advice is effective in achieving short-term weight loss, especially in males.
