on research investigating weight regain




" If I look back now and ask myself if I would do it again, I don’t know, I am inclined  to say no. All the measurements, all the protocols, the fat biopsies - it is a big commitment. But if after one more year, I still have not regained weight and have still adapted my food intake, perhaps I will have another opinion – and say I would do it again. It is all in the head – that’s where it takes most time to establish change. "

With prevalence of obesity among adults and children reaching epidemic proportions across Europe, evidence based guidance on what works best for those who struggle to maintain a healthy weight is urgently required.
With 1000 family participants across 8 national centres, the data collected during the Diogenes study will provide the evidence base that policy makers and professionals need to make recommendations to consumers.

The progress of this 8 country human dietary intervention trial, focused on identifying the diets which are most successful in helping to stop weight regain after initial weight loss has been recorded on DVD.

The total recording is 30 minutes, broken into chapters or sections as listed below.
As well as mapping the project, the DVD contains useful insights from researchers and subjects on the challenges and benefits of the Diogenes study.
