Take the FCS 10g Fat Challenge

Friday 7 November 2025

The first Friday of November is FCS Awareness Day, this year on 7 November. On this one day we invite you to 'Take the FCS 10g Fat Challenge' and eat just 10g fat for the day.

We hope that by doing so we will raise awareness of the daily challenges faced by people with the condition - and those close to them, and you will gain some insight of the impact the condition has on the daily life of those who are affected by it.

People with FCS are recommended to:

  • eat less than 20g fat per day (all types of fat),
  • reduce added sugars
  • avoid alcohol
  • many find 10g fat is the better target.

‘ Fat’ for people with FCS means all types of fat.

  • no fat from oil, and from the foods from which the oils are derived – for example nuts, seeds, avocados, coconut, and olives;
  • no animal fats, so most meats unless great care is taken about how lean it is and any visible fat is removed.  It can often be difficult to judge how much fat is in meat;
  • no fat from dairy, fat-free or low-fat are suitable but often contain high levels of added sugar; and
  • no fat from egg yolks.

FCS dietary guidelines

Here are some resources to help you through the day. Key to success is planning!

Don't miss meals, and always have a suitably low-fat snack with you to stave off cravings and avoid bad decisions.

To prepare, you might want to think about:

  • what you might eat
  • where you might eat - if you're out
  • what you might need to take with you
  • what will be difficult to do
  • how will you explain why you can't eat what's offered you?
