How Many Calories Are in My Meal? 3 AI Ways to Find Out

"How many calories is this?" used to mean kitchen scales and database searches. Today AI can answer it in seconds — and the best method depends on what's in front of you. Here are the three ways, and when each one wins.

1. Take a photo (plated meals)

For a home-cooked plate or a restaurant dish, a photo is fastest. AI vision identifies every item — even several foods on one plate — estimates the portions and returns calories, protein, carbs and fat. Frame the whole plate in decent light, then review the breakdown and nudge any portion that looks off.

2. Scan the barcode (packaged food)

Anything with a label deserves exact numbers, not estimates. Scanning the barcode looks the product up in a database of millions of items and fills in the manufacturer's own nutrition facts, scaled to your serving. When a product isn't found, a photo or quick manual entry covers the gap.

3. Describe it in plain language (everything else)

Ate something with no packaging and no photo opportunity — like "a chicken sandwich and a donut" at your desk? Type exactly that. AI proposes the individual items with estimated amounts and nutrition, ready to adjust and save. It's the same natural way you'd ask a chatbot, but the answer lands in your diary and counts toward your daily targets.

Which method should you use?

• Plated or restaurant meal → photo.
• Packaged product with a label → barcode.
• No photo, no package, or a meal already eaten → describe it in text.

CalorieAI puts all three one tap from the home screen, so the honest answer to "how many calories is my meal?" is: about three seconds away.
