Calorie Counter GPT

Calorie Counter GPT

A focused visual calorie tracker that lets anyone estimate nutrition from a quick photo or a short description. The agent uses GPT 4o Vision together with a curated food composition database to turn pictures into precise calorie and macro information, then keeps an ongoing daily log and offers gentle coaching toward your target energy budget.

What you can do

  • Snap a meal photo and receive instant calories, protein, fat, carbohydrate and selected micronutrients
  • Paste or dictate a text description when a photo is not available
  • Store every entry in the current chat so you always see running totals for the day
  • Ask for personalised targets based on your body data, activity level and diet goal
  • Get meal by meal suggestions to close macro gaps or adjust portions
  • Export the log as plain text or CSV at any time

Why it matters

Keeping an accurate food journal is the strongest predictor of diet success, yet manual logging is tedious. Vision plus language removes that friction, letting people act on reliable numbers rather than guesses. For athletes and patients with clinical nutrition needs, rapid feedback is crucial for performance and adherence.

Quick start

  1. Open Calorie Counter GPT on ChatGPT
  2. Sign in with your OpenAI account
  3. Drop a photo of your meal or type the ingredients

Try: “Here is my breakfast” together with a top down phone picture. Follow up with “Show me today’s macro totals”.

How it works behind the scenes

Everything happens entirely inside ChatGPT. When you share a meal photo or a text description, the content is passed to GPT 4o Vision together with a compact system prompt that lists common portion sizes and asks for nutrient estimates per item plus a confidence score. The model replies with a structured list of calories and macros. A small helper file inside the GPT conversation tracks running totals until the chat ends.
