Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective is to compare the effectiveness of 4 different commercial weight-loss diets available to adults in the UK.

This is achieved with a 6 month multi-centre randomised unblinded controlled trial of

* Dr Atkins' New Diet Revolution,
* The slimFast Plan,
* The weight Watchers Pure Points Programme,
* Rosemary Conley's "Eat Yourself Slim" Diet \& Fitness Plan.
* No diet (control)

Subjects are a community based sample of 300 (60 per group) otherwise healthy overweight and obese adults.

Main outcome measures are weight and body fat change over 6 months.
