What is the relationship between Garmin Connect and MyFitnessPal?
The direct answer is **no, Garmin Connect does not use MyFitnessPal (MFP) to calculate your resting calories**. Garmin has its own proprietary algorithm for this calculation. Your Garmin watch and the Garmin Connect app calculate your resting calories based on the personal information you provide: age, height, weight, and gender. This value is an estimate of your Basal Metabolic Rate (BMR) or Resting Metabolic Rate (RMR), which is the energy your body burns just to stay alive (e.g., breathing, circulation).
While the two platforms can be linked, their data synchronization serves different purposes. When connected:
- MyFitnessPal sends your **caloric intake** (food logs) to Garmin Connect.
- Garmin Connect sends your **active calories** (from tracked workouts and daily steps) to MyFitnessPal.
- Weight data can be synced between both platforms.
This integration allows you to see your “calories in vs. calories out” in one place, but the core calculation of resting calories remains independent within the Garmin ecosystem. MyFitnessPal performs its own BMR calculation based on your profile, which is why you might see different resting calorie numbers on each platform.
The Resting Calories Formula and Explanation
While Garmin’s exact algorithm is proprietary, it is based on established formulas for calculating Basal Metabolic Rate (BMR). The most widely used and respected formula today is the **Mifflin-St Jeor Equation**, which our calculator uses. It has been shown to be more accurate than older formulas like the Harris-Benedict equation.
The formula is as follows:
BMR (kcal/day) = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) + s
Where ‘s’ is a gender-specific value: +5 for males and -161 for females.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Weight | Your body mass | kg or lbs | 50 – 150 kg |
| Height | Your stature | cm or in | 150 – 200 cm |
| Age | Your age in years | years | 18 – 80 |
| Gender (‘s’) | A constant to adjust for physiological differences | Unitless | +5 (Male), -161 (Female) |
Practical Examples
Example 1: Active Male
- Inputs: Age: 30, Gender: Male, Weight: 190 lbs, Height: 72 inches
- Units: Imperial
- Results: With these inputs, the calculated BMR is approximately **1,938 calories/day**. This is the energy he needs at complete rest. His total daily burn on Garmin, including workouts and steps, would be significantly higher.
Example 2: Sedentary Female
- Inputs: Age: 45, Gender: Female, Weight: 68 kg, Height: 165 cm
- Units: Metric
- Results: Her calculated BMR is approximately **1,372 calories/day**. Garmin would report this as her “Resting Calories”, and any movement throughout the day would be added as “Active Calories”.
How to Use This Resting Calories Calculator
- Enter Your Age: Input your current age in years.
- Select Your Gender: Choose Male or Female from the dropdown. This adjusts the final calculation.
- Provide Your Weight: Enter your weight and select the correct unit (lbs or kg).
- Provide Your Height: Enter your height and select the correct unit (in or cm).
- Interpret the Results: The calculator instantly shows your estimated BMR, which is a close proxy for Garmin’s “Resting Calories”. The chart helps you see how you compare to population averages.
Key Factors That Affect Resting Calories
- Body Composition: Muscle tissue burns more calories at rest than fat tissue. A more muscular person will have a higher BMR.
- Age: BMR naturally decreases with age as muscle mass typically declines.
- Weight: A heavier body requires more energy to maintain, resulting in a higher BMR.
- Height: Taller individuals have a larger body surface area, which leads to a higher BMR.
- Gender: Men generally have more muscle mass and a higher BMR than women of the same age and weight.
- Genetics: Your genetic makeup plays a significant role in your metabolic rate.
Frequently Asked Questions (FAQ)
1. Does Garmin use MyFitnessPal for resting calories?
No, Garmin calculates resting calories using its own algorithm based on your user profile (age, weight, height, gender). MyFitnessPal is used to sync food intake and activities.
2. Why are my Garmin resting calories different from MFP’s goal?
Both platforms calculate BMR independently using their own formulas and potentially different interpretations of your activity level. They are usually close but rarely identical.
3. How does Garmin calculate active calories?
Active calories are calculated using heart rate data, step counts, and the type of activity you are performing. This is added on top of your resting calories.
4. How can I make my Garmin calorie count more accurate?
Ensure your profile information (age, weight, height, gender) is always up-to-date in Garmin Connect. Wearing the watch consistently, especially during sleep, also helps improve accuracy.
5. Is BMR the same as Resting Calories on Garmin?
They are very similar. BMR is the energy burned in a true state of rest (like right after waking up). Garmin’s “Resting Calories” represents your BMR plus the energy for very light, non-exercise movement throughout the day, so it’s often slightly higher than a strict BMR calculation.
6. What data syncs between Garmin and MFP?
Garmin sends workouts, steps, and active calories to MFP. MFP sends logged food (calories and macros) to Garmin. Weight can sync both ways.
7. Can I manually change my resting calories on Garmin?
No, you cannot directly edit the resting calorie value. It is automatically calculated based on your profile stats.
8. Which is more accurate for total calorie burn, Garmin or MFP?
Garmin is generally considered more accurate for total calories burned because it uses real-time biometric data (like heart rate) to determine active calorie expenditure, whereas MFP often relies on estimates for activities.
