The history

The 1:1 Diet was founded by Dr Alan Howard way back in the 60's. He was one of the original pioneers of obesity research and founder of the International Journal of Obesity - who spent 50 years at the University of Cambridge, most of it researching and devising the optimum weight-loss diet.

Over the last 35 years, dozens of studies have been published on the core components to The 1:1 Diet; one-to-one support, products and Plan, consistently demonstrating their safety and efficacy. Check them out below:

Largest Ever Diabetes Prevention Study

Our products and Plan were also used successfully in the largest ever, multi-national study of diabetes prevention.

Study Subjects Keep Using The 1:1 Diet

All of the above studies resulted in over 10 kilos of weight loss and in the recent DROPLET weight-loss study, subjects again lost more than 10 kilos and improved multiple markers of health.

Subjects were so impressed with the diet plan, that 62% of them continued The 1:1 Diet at their own expense at the end of the study.
