# How to Research Macronutrient Profiles with ChatGPT

ChatGPT explains macronutrient data in the context of your actual goals. It does not just show you that chicken has 31g of protein per 100g -- it explains why that matters for muscle building, suggests meal combinations that hit your macro targets, and recommends foods you might not have considered. Nutrition data becomes actionable diet advice.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "What is the macronutrient breakdown of almonds per 100g?"
3. ChatGPT returns the detailed macro profile
4. Request: "Find me five high-protein, low-carb foods and compare their macros"
5. Use the analysis for your diet planning

## Example Prompt

```
I need high-protein, low-carb foods for a keto diet. Look up the macros for steak, eggs, cheese, salmon, and avocado. Present as a comparison table.
```

## Tips

- ChatGPT can explain why certain macro ratios matter for specific goals
- Ask for food suggestions that fill gaps in your current macro intake
- Request meal combinations that hit specific macro targets
