What photo-based food logging is
Photo-based food logging uses AI to recognise the foods on your plate and estimate how much of each is there. From that, it estimates calories, macronutrients like protein, carbohydrate and fat, and other key nutrients.
The big advantage is speed. Snapping a photo takes seconds, which makes it much easier to log consistently than typing in every ingredient by hand.
Photo logging also captures meals as you actually eat them. Instead of guessing which database entry matches your plate of waakye with gari, egg and fish, you log the whole plate in one go.
How Dunu works
With Dunu, you take a photo of your meal and get an estimate of calories, macros and key nutrients. Dunu is built with Ghanaian dishes in mind, so foods like banku, red-red and jollof are recognised as meals rather than generic rice or dough.
You also get health scores tuned to your goals, such as weight management or blood pressure, so you can see how a meal fits your priorities at a glance.
- Snap a photo of your plate
- Review the estimated calories, macros and key nutrients
- Correct the food name if it is not quite right
- Set how much you actually ate
- See health scores tuned to your goals
Be realistic: these are estimates
No photo app can know exactly how much oil went into a stew or how dense a ball of kenkey is. Results are estimates, and they can be off, especially for mixed dishes, hidden ingredients and unusual portion sizes.
That is still useful. For most people, a consistent, reasonable estimate is enough to spot patterns, compare meals and make better choices. You do not need perfect numbers to make progress.
Tips for better estimates
A clear photo helps the AI identify foods and judge portions. Small habits make a noticeable difference to the quality of your estimates.
If the food name is wrong, correct it, and adjust the amount if you shared the meal or left some behind.
- Shoot from slightly above in good light
- Keep the whole plate or bowl in the frame
- Separate items a little where you can
- Snap before you start eating
- Correct the name or amount if needed
Turn logging into insight
The value of logging comes from looking back. After a week or two, you will see which meals keep you full, where sugar or salt creeps in, and how portions vary.
Pair meal logs with water, weight, blood pressure or blood sugar tracking in Dunu to get a fuller picture. If you have a medical condition, share your trends with your doctor or dietitian rather than relying on estimates alone.
Who photo logging is for
Photo logging suits anyone who wants a clearer picture of their eating without the hassle of weighing food. It works well for people managing their weight, building muscle, or trying to cut back on salt or sugar.
It is not a substitute for medical advice. If you have diabetes, kidney disease or another condition that needs precise nutrition, use photo estimates as a guide and follow your healthcare team's plan. A registered dietitian is available on Dunu's Personal and Family plans if you want expert support.
This is general nutrition information, not medical advice. Numbers are estimates that vary by recipe and portion. If you are managing a health condition, talk to your doctor or a dietitian before changing your diet.
