PROJECT
The TANGO Diet Trial
Purpose
The purpose of the TANGO Diet Trial is to compare the long-term effectiveness of two weight loss programs involving fast weight loss (i.e., weight loss of approximately 0.5 to 2 kilograms per week), achieved using medically-supervised meal replacement diets. These ‘severe diets’ involve replacing all regular meals and snacks with nutritionally replete meal replacement products, such as shakes.
Severe diets have been shown in research to have surprising benefits: motivation associated with fast weight loss; hunger control; pain reduction; and mood improvements, among other benefits. However, keeping weight off after a severe diet – or indeed after any weight loss diet – is difficult for most people.
The TANGO Diet Trial aims to find better ways to help people to keep weight off after a severe diet.
This research trial is being conducted at the University of Western Australia, and is funded by the National Health and Medical Research Council (NHMRC) of Australia.

The TANGO Team is seeking 288 participants for the TANGO Diet Trial. Participants will receive a 1-year weight loss program to help them achieve their weight loss goals.
