## Description

Fitness and health agents need to get the math right. When you ask a standard AI to guess how many calories you burned during a specific hike or gym session, it's basically throwing darts at a board. This Connector changes that by giving your agent a deterministic engine built on validated MET (Metabolic Equivalent of Task) values. Instead of hallucinating numbers, your agent pulls from a native catalog of over 80 physical activities to calculate exact burn rates based on the user's weight and time spent moving. It also handles the heavy lifting for metabolic profiling, using the Mifflin-St Jeor equation to establish BMR and TDEE without needing to send sensitive health data to the cloud. If a user wants to know how long it will take to hit a goal, the Connector calculates the exact days and weeks required based on a specific caloric deficit. It's the difference between a vague "you'll lose weight" and a concrete "at this deficit, you'll reach your goal in 154 days." You can find this and thousands of other tools in the Vinkius catalog to build out your agent's capabilities.

## Tools

### estimate_calories_burned
Calculates calories burned for a specific activity based on user weight and time. This ensures your agent provides accurate burn data.

### search_activity_catalog
Searches a local database to find MET values for over 80 different physical activities. This helps the agent identify the right exercise type.

### calculate_weight_loss_projection
Projects the number of days or weeks to reach a goal based on a daily calorie deficit. This helps users see a realistic timeline.

### calculate_tdee
Computes BMR and TDEE using the Mifflin-St Jeor equation for accurate metabolic profiling. It keeps health metrics private and local.

## Prompt Examples

**Prompt:** 
```
I weigh 80kg and ran moderately for 45 minutes. How many calories did I burn?
```

**Response:** 
```
Based on the activity catalog, a moderate run has a MET value of 9.8. For your weight of 80kg over 45 minutes, you burned approximately **588 calories**.
```

**Prompt:** 
```
I am a 30-year-old male, 180cm, 85kg, with a sedentary lifestyle. What is my TDEE?
```

**Response:** 
```
Using the Mifflin-St Jeor equation, your **Basal Metabolic Rate (BMR)** is 1,830 kcal/day. 

With a sedentary lifestyle, your **Total Daily Energy Expenditure (TDEE)** is approximately **2,196 kcal/day**.
```

**Prompt:** 
```
I weigh 90kg and want to reach 80kg with a 500 calorie daily deficit. How long will it take?
```

**Response:** 
```
To lose 10kg, you need to burn 77,000 calories. 

At a consistent deficit of 500 calories per day, it will take exactly **154 days** (about 22 weeks) to reach your goal.
```

## Capabilities

### Calculate burned calories
The agent calculates exact calorie burn based on specific activity types, user weight, and duration.

### Search activity catalog
Your agent can browse a local list of over 80 physical activities to find correct MET values.

### Establish metabolic rates
It uses the Mifflin-St Jeor equation to determine BMR and TDEE without cloud processing.

### Project weight loss timelines
The agent calculates exactly how many days or weeks it will take to hit a target weight.

### Provide safety warnings
It includes warnings for aggressive weight loss goals to ensure user safety.

## Use Cases

### Precise calorie tracking for workouts
A user asks how much they burned on a 30-minute moderate run. The agent uses search_activity_catalog and estimate_calories_burned to give a precise number.

### Realistic goal setting for clients
A personal trainer wants to know if a client's goal is realistic. The agent uses calculate_weight_loss_projection to show a 154-day timeline.

### Privacy-first metabolic profiling
A fitness enthusiast wants to know their daily calorie limit. The agent uses calculate_tdee to provide a BMR and TDEE breakdown without sending data to the cloud.

### Building reliable health bots
A developer wants to build a custom health bot that doesn't hallucinate math. They connect this Connector to ensure all metabolic data is grounded in science.

## Benefits

- Stop LLM hallucinations by using deterministic MET values for all activity-based calorie calculations.
- Keep user health data private by performing all BMR and TDEE calculations locally via the Mifflin-St Jeor equation.
- Provide users with concrete weight loss timelines instead of vague estimates using the calculate_weight_loss_projection tool.
- Access a diverse list of over 80 activities through the search_activity_catalog to ensure every workout is covered.
- Deliver professional-grade metabolic profiling that matches the accuracy of dedicated fitness apps.

## How It Works

The bottom line is that your agent stops guessing and starts using validated science to provide accurate fitness data.

1. The agent searches the local activity catalog to find the correct MET value for a specific movement.
2. It takes user inputs like weight, height, age, and duration to run the math.
3. It returns a precise calorie count or a multi-week timeline for weight goals.

## Frequently Asked Questions

**Can the Metabolic Energy Estimator give me exact calorie counts?**
Yes, it uses a catalog of 80+ activities to calculate precise burn rates based on your specific weight and the duration of your workout.

**How does the Metabolic Energy Estimator calculate my TDEE?**
It uses the Mifflin-St Jeor equation, which is a standard scientific method for determining your Basal Metabolic Rate and Total Daily Energy Expenditure.

**Is my health data safe with the Metabolic Energy Estimator?**
Yes, all metabolic calculations happen locally through the Connector, so your weight, height, and age aren't sent to external cloud services.

**Can I use the Metabolic Energy Estimator to see how long it takes to lose weight?**
Absolutely. It can project a specific timeline in days and weeks based on your target weight and your daily caloric deficit.

**What kind of activities are included in the Metabolic Energy Estimator?**
It includes a catalog of over 80 different physical activities with validated MET values.

**Why should I use this instead of just asking my AI?**
Standard AI models often guess numbers, which can be inaccurate. This Connector ensures the math is deterministic and scientifically grounded.

**How does it calculate the calories burned?**
The estimate_calories_burned tool uses the standard metabolic formula: Calories = MET * weight(kg) * time(hours). It pulls the exact MET value from its internal activity catalog.

**What formula is used for Basal Metabolic Rate (BMR)?**
The calculate_tdee tool uses the Mifflin-St Jeor equation, which is currently considered the most accurate standard for predicting resting metabolic rate.

**How does it project weight loss?**
The calculate_weight_loss_projection tool uses the biological constant that 1kg of body fat equals approximately 7700 calories. It divides the total required deficit by your daily deficit to predict the exact timeline.
