Studies have shown that AI models like ChatGPT can have an average error of 10-30% in calorie and macronutrient calculations, severely hindering any precise diet plan. This reveals significant accuracy issues when using ChatGPT for calorie counting, especially for complex or homemade meals.

According to one test using GPT-4o, the AI model demonstrated a median absolute error of 2.4% for men and 5.7% for women when estimating body fat from visual guides. These findings, which are surprisingly close to clinical standards like DEXA scans under specific conditions, raise questions about the reliability and practicality of using AI chatbots for personal body composition analysis. While the technology shows promise, its accuracy is highly variable and depends on a multitude of external factors that users must understand before relying on AI for fitness metrics.

According to expert testing in 2025, the accuracy of AI calorie counting apps from food photos ranged from 50-82%, demonstrating that while the technology is powerful, it is not flawless. The answer is yes, you can take a picture of food to count calories for free, but it's important to understand the capabilities and limitations of these AI-powered tools.

Recent studies have explored the capabilities of AI in dietary assessment, with some suggesting that for simple foods, AI can achieve similar accuracy to human estimation. This raises a critical question for dieters everywhere: **Can ChatGPT accurately count calories?** While the technology offers a convenient new tool, its limitations—particularly concerning portion sizes and meal complexity—are crucial to understand.
