Why it works

Here comes the sciency bit about The 1:1 Diet; The Consultants, products and Plan

The effectiveness of our diet Plan is not just based on our proven, nutritionally-balanced products. You get a tailored-made, flexible Plan, with one-to-one support from a trained Consultant to make sure you hit your goals - big or small.

The Consultants 

The regular, one-to-one visits with our trained Consultants are a crucial aspect of The 1:1 Diet. This kind of support has been proven to help optimise effective weight-loss.

The Plan

Our Plan has been proven effective in multiple studies and has been continually developed, improved and refined over 36 years, using the latest evidence and observing the experiences and outcomes of millions of dieters.

The products

Our products are designed to replace as few as one meal and as many as all of your normal meals in your diet, depending on your particular needs and goals. They contain the recommended levels of all essential vitamins, minerals and other nutrients and have been shown to lead to substantial weight loss through calorie restriction and better dietary intake.
