Basal Metabolic Rate

Basal Metabolic Rate (BMR) refers to the minimum amount of energy (calories) your body needs at rest to sustain essential functions such as breathing, circulation, and organ function. Even while sleeping, your body requires energy to keep your heart, brain, liver, kidneys, and nervous system functioning effectively.

Why Does BMR Matter?

Your muscle mass significantly influences BMR. The more muscle you have, the higher your BMR, meaning your body burns more calories, even at rest. A higher BMR can make weight management easier by helping you burn more energy throughout the day.

Conversely, a lower BMR means your body burns fewer calories at rest, making it harder to lose fat and maintain a healthy weight.

BMR and Total Daily Energy Needs

It’s important to remember that BMR is not your total daily calorie requirement. To determine how many calories you need per day, you must also factor in your daily activities and exercise levels.

• If you consume fewer calories than you burn, you will lose weight.
• If you consume more calories than you burn, your body stores the excess energy, leading to weight gain.

How Tanita Body Composition Monitors Help

Tanita body composition monitors automatically calculate your BMR using medically validated equations based on electrical impedance, weight, and personal data.

By understanding your BMR and activity level, you can determine how many calories you need daily—whether to maintain your weight, lose fat, or optimize muscle gain. For safe weight loss, it is crucial to never consume fewer calories than your BMR, as this could impact overall health.

Tanita body composition monitors display BMR in both kilocalories (kcal) and kilojoules (kJ), just like temperature is measured in Celsius and Fahrenheit—different units but the same data.

Tracking BMR helps you make informed nutrition and fitness choices, leading to better long-term health and wellness management.
