Frequently Asked Questions
Do I need to create an account?
No. Your food diary is stored locally in your browser. This means it's private and instant - but won't sync between devices. Make sure not to clear your browser data if you want to keep your entries.
Where do I find kJ values for food?
Check Australian food labels (kJ is always listed), use our Food Nutrition Tables, or search online for "food name kJ". Most packaged foods in Australia display kJ per serve and per 100g.
How many kJ should I eat per day?
This depends on your age, gender, weight, and activity level. Use our Daily Energy Needs Calculator to find your maintenance level, then reduce by 2,000-3,000 kJ per day for weight loss.
