Keeping Track of What You Eat and Drink
A food diary is a useful way to record everything you eat and drink throughout the day. Keeping a diary can help healthcare professionals understand your eating habits, identify any nutritional concerns, and provide personalised advice to support your health and wellbeing.
Why Keep a Food Diary?
Recording your food and drink intake can help:
- Identify eating patterns
- Monitor appetite and food intake

What Should Be Recorded?
Try to record everything you eat and drink, including:

The more detailed your diary is, the more useful it will be.
