AI 卡路里扫描怎么做：用照片计算卡路里

Counting calories used to mean searching a food database, guessing portion sizes, and logging every ingredient. A photo calorie counter changes that: snap your plate and an AI food calorie scanner estimates calories from the photo in seconds.

Step 1: Computer Vision Identifies Your Food

When you take a picture of food to count calories, SnapFood's AI analyzes color, shape, texture, and context. It can recognize salads, sandwiches, pasta, takeout, rice bowls, and mixed plates — the same workflow as scanning a plate for calories.

Step 2: Portion Estimation

The AI estimates serving size from plate area, food volume, and nearby objects so you can estimate calories from a food photo without weighing each item. Bright light and a full view of the meal usually improve the calorie count from a photo.

Step 3: Nutrition Calculation

Once dishes are identified, SnapFood matches them to nutrition data and shows calories plus protein, carbs, fat, and fiber — a full AI nutrition analysis from one meal photo, not just a single calorie number.

• Snap or upload a meal photo to count calories
• AI identifies each food item on the plate
• Calories, protein, carbs, and fat display instantly
• Review simple nutrition tips for the meal
