the Diet Color tool

What is the Diet Color?

  • To help you find a varied diet tailored to your needs during your slimming journey slimming, we made the Diet Color system available.
    It lets you customise every day your menus and is based on the calculation of average daily energy needs.

How does it work?

  • Depending on your diet programme and your lifestyle, your dietitian develops your menu types. Each menu is composed of coloured dots that represent a category of foods.
    With one click, you can customise your menus, and replace each colour dot with a tasty recipe, using the Diet Expert library of recipes.
    Thus instead of getting fed up, each meal is a pleasure throughout your programme. We wanted to make this tool as interactive as possible, providing recipes in photos and/or videos.
