Automate Nutrition Tracking with LINE & Google Gemini Workflow

Automate Nutrition Tracking with LINE & Google Gemini Workflow

Transform the way you monitor your meals with our cutting-edge workflow that bridges LINE and Google Gemini. Simply snap a photo of your meal, send it via LINE, and let this automation take care of the rest. Effortlessly track your nutrition by getting detailed analyses and actionable health advice directly from Google Gemini, while all your data is neatly logged and organized for future reference.

What this Workflow Does

• Receives a POST webhook event from LINE whenever you send a message.
• Verifies if the incoming message includes an image and halts if it does not.
• Downloads the image content through the LINE Messaging API and forwards it to Google Gemini, which identifies food items, estimates nutrition facts, and generates health advice.
• If the image is not food-related, you receive a LINE push message prompting a clearer meal photo.
• When valid, the AI-generated response is parsed into structured fields such as food items, macronutrients, calorie content, and personalized advice, alongside remaining calories based on your daily goal.
• The meal image is uploaded to Google Drive, and a nutrition log is appended to Google Sheets, which includes the image URL. The summary is then sent back to you via LINE.

Use Cases

• For health-conscious individuals seeking to automate the tracking of their daily caloric intake and nutritional values.
• Busy professionals who want to streamline meal tracking without manual logs or multiple apps.
• Nutritional consultants and dietitians who wish to leverage technology for client meal analysis and reporting.
• Developers working on health tech solutions needing inspiration for food tracking integrations.
