Using Garmin Venu 3 to monitor nutrition: tracking calories and macronutrients

Smart Garmin Venu 3 sports watch is not just a standard set of features for workouts or tracking health and fitness metrics. This device can become your essential assistant for monitoring and tracking your nutrition.
Syncing Garmin Venu 3 with the appropriate apps for tracking calories and macronutrients can help you reach your fitness goals. Managing this functionality is easy and the results can exceed your expectations.
What affects calories burned
How many calories our body burns depends on the work it does. The most important factor is the intensity of effort. By measuring your heart rate, the Garmin Venu 3 sports watch accurately calculates workout intensity. That’s why it’s important to choose the right activity type, such as walking, cycling, or others.
The Garmin Venu 3 also “understands” how your body responds to exercise, for example if it’s getting fatigued, by measuring heart rate variability (HRV). Additionally, when setting up the watch you enter your gender, height, weight and age — these details are also factored into the calorie burn calculation.
How Garmin calculates calories
A key factor affecting how the Venu 3 calculates calories is your VO2 max. To estimate your VO2 max, the Garmin watch considers multiple factors including, besides the ones mentioned, your breathing rate and for cycling, power sensor data.
Firstbeat analytics on Garmin devices ensures the accuracy and reliability of statistical data such as estimated maximal oxygen consumption and calories burned. Over the years, Finnish company Firstbeat has developed precise algorithms to improve measurement accuracy for various metrics, including calories burned.
How to make your Garmin Venu 3 measure calories most accurately
Here are some tips to improve calorie measurement accuracy:

• if possible, use an HRM strap for workouts instead of the optical sensor
• wear your Garmin women’s watch Venu 3 regularly during different exercises
• if your watch tracks sleep, try to wear it on your wrist consistently while sleeping
• make sure the settings data (gender, age, height, weight) is correct
• if using wrist-based optical measurement, ensure the watch fits snugly and is not too loose

Resting calories and active calories — what’s the difference? Resting calories are the ones your body uses for everyday vital functions. That’s why it’s normal for the watch to show 700-1000 calories burned when you wake up in the morning. This is just the sum added for accurate calculation of all calories burned during the day.
Active calories, meaning those consumed during physical activity, are added to resting calories throughout the day. Together they give the total calories burned — the total energy your body has used over the course of the day.
