The 1:1 Diet by Cambridge Weight Plan is research-proven to be safe and effective. See the studies here.

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:

Landmark Research on Diabetes

Recently, the DiRECT study, based upon our products and Plan, has changed the way doctors and dietitians all around the world think about the reversal of diabetes. You can read the full research here

Huge NHS Pilto Study Based Upon Our Plan

In fact, based upon the incredible results of DiRECT, the NHS and Diabetes UK have commissioned a pilot Type 2 diabetes remission study of 5000 patients.

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.

Why not take a peek at some of the
other research we’ve got?

The DiRECT study has proven that it is possible to put Type 2 diabetes into remission using a low-calorie formula diet-based weight management program.

DiRECT has proven that it is possible to put Type 2 diabetes into remission using a low-calorie formula diet-based weight management program. (That’s one of the great things The 1:1 Diet by Cambridge Weight Plan does.)

The results showed that more than a third of dieters who lost over 10 kilos on the program had put their diabetes into remission.

Pretty impressive, hey! We’re definitely proud of these results!

Professor Anthony Leeds, Medical Director at The 1:1 Diet by Cambridge Weight Plan, said:

“It’s great to see further evidence that Type 2 diabetes can be reversed through significant weight loss. This follows another report showing Total Diet Replacement programs, combined with one-to-one support, are an effective and cost-efficient way to lose weight long term.

“We’ve seen hundreds of people on our plan successfully reverse their Type 2 diabetes, while still maintaining their weight loss. This is all through a simple program of low-calorie formula products and one-to-one support from a Consultant.”

Why are we so special?

We’ve got our 3Ps. Our Products (which this research shows really do work) and our Plan. But more importantly, we’ve got our People. The Consultants who support their dieters through every stage of their weight loss journey. The Consultants are the final magic ingredient to a really successful diet – it’s like having your own cheerleader, keeping you going when it gets tough (which it does with all diets!).
