A trial looking at diet for women with a family history of breast cancer (BRRIDE2)

This trial is comparing 2 diets to help women who are at an increased risk of breast cancer to lose weight.

We know that being overweight can increase your risk of developing breast cancer. We also know that losing weight can reduce the risk. This trial is part of a programme to find the ideal diet to help people lose weight.

The trial team consider that an ideal diet

• Meets all your nutritional needs but is low enough in calories to help you lose weight

• Is easy to follow

• Helps you lose body fat, including fat from around the vital organs in your tummy (abdomen) but won’t affect your muscles

• Doesn’t affect the amount of calories your body burns each day (your metabolic rate)

In this trial, the researchers are comparing a diet of low calorie healthy eating every day, with an intermittent diet. The intermittent diet is a low carbohydrate and low calorie diet for 2 days in a row each week, and a healthy diet for the other 5 days.

The aim of the trial is to compare these 2 diets to find out which might be the ideal diet for women who are at an increased risk of developing breast cancer to lose weight.
