Calorie Calculator

Of course exercise and other activities burn calories – but how many?

Find out how many calories you use while performing your favorite activities – and then adjust your caloric intake accordingly. While it’s good to know your Resting Metabolic Rate and Daily Caloric Needs, don’t forget that the specific exercises and activities of your day will add to the number of calories your body uses.

Resting Metabolic Rate Calculator

How many calories does your body use when you’re doing absolutely nothing?

Whether you’re trying to lose, gain, or maintain weight, knowing your resting metabolic rate (RMR) gives you a clear understanding of how many calories it takes for your body to perform its basic functions.

Your Resting Metabolic Rate (RMR) is the minimum number of calories your body needs to support its basic physiological functions, including breathing, circulating blood, and numerous biochemical reactions. Your RMR is generally equal to 60-75% of your total daily caloric expenditure.

Daily Calorie Calculator

Before you adjust your caloric intake, find out how many calories you must consume each day to maintain, gain, or lose weight. Pinpointing that number with our calorie weight loss calculator can give you more control of your BMI (body mass index).

It’s also important to know how many calories your body requires just to maintain certain daily activities. By combining your resting metabolic rate and your daily activity level, you’ll get a calorie target for the day.
