Calculate Your Daily Calories

Use this calorie calculator to determine how many daily calories your body needs to lose, gain, or maintain your weight.

Activity Level Defined

According to the most commonly used formula, activity levels are defined as follows:

Sedentary Lifestyle

Little or no exercise

Lightly Active Lifestyle

Light exercise or sports 1-3 days/week.

Moderately Active Lifestyle

Moderate exercise or sports 3-5 days/week.

Very Active Lifestyle

Hard exercise or sports 6-7 days/week.

Extra Active Lifestyle

Hard exercise or sports 6-7 days/week.

Note: This calculator will under-estimate calorie needs for very muscular individuals and will over-estimate calorie needs for over-weight individuals.

A calorie is a unit of energy. Generally, a calorie refers to energy consumption through food and beverage consumption and the amount of energy usage spent through physical activity. Everyone requires different amounts of energy per day depending on their age, size, and activity levels. Using the calculator above will help you determine your specific daily caloric needs.

In order to maintain your current weight, you must consume the same number of calories as you burn. Conversely, if you want to lose weight, this can be accomplished by consuming less calories or burning more calories. If you wish to consume less throughout your day, you will want to eat 500-1,000 fewer calories per day than calculated, or as an alternative, eat 15-20% fewer calories than calculated.

If you wish to burn more calories over consuming fewer, you should increase your physical activity – you can consume more calories and still sustain weight loss as long as you eat fewer calories than calculated. Keep in mind that leaner bodies need more calories than less lean bodies. Lastly, if you wish to gain weight, you need to consume more calories than you burn. This should be accomplished by having a caloric-dense diet with regular exercise.

Basal metabolic Rate (BMR)

Your Basal Metabolic Rate (BMR) measures the amount of calories your body burns while at rest. Some body processes requiring energy, such as breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles.

Your BMR accounts for roughly 60 to 75% of your daily calorie expenditure.

BMR will always vary from person-to-person. Some intrinsic factors affecting your Basal Metabolic Rate include weight, height, gender, body composition and temperature, age, hormone levels, and your overall health.

In General, Metabolic Rates Will:

Metabolic Rates

increase with an increase in body weight and height.

lower fat tissue

be lower in fat tissues that muscle tissue.

Metabolic Rates lower for women than men

be lower in women than men.

Metabolic Rates decrease with age

decrease with age.

Metabolic Rates increase body temperature

increase with an increase in body temperature.

T4 hormone levels

vary in response to T4 hormone levels.

To lose weight, you will need to reduce your daily caloric intake below your total daily calorie requirement indicated by your BMR plus your activity level. A few ways to increase your activity levels range from dedicating more time to working out or finding little ways to stay more active throughout the day.

If you’re looking to burn more calories without sacrificing a lot of time from your day
