Calorie Calculator

Calorie Calculator Tool

Calories, calories, calories. While calories are often discussed, they’re often misunderstood. A calorie can be a fantastic guidepost to understand the food you are putting into your body as fuel and how you are using that fuel each day. A caloric defecit and you will lose weight over time, a caloric surplus and you will gain weight. Depending on your goals – we wanted to help put a fantastic tool together that can be useful for either one. Our Calorie calculator follows a very simple and straightforward process – simply enter your personal information (height, weight, age, gender) and we’ll not only spit out what your expected calories spent each day are, but we’ll provide five different results to help you understand where you probably fit within the recommended ranges. No one is completely “sedentary” each day, or “extremely active”, that’s why we wanted to show you all of the options, so you can make informed decisions about your health. If you like that idea – and want to check out the other tools we’ve built, feel free to swing over to our health and fitness calculator section and try our other ones out!

Calorie Calculator


Calorie calculation is a process used to determine the energy an individual’s body needs to function, and the count burned during exercise or other activities. This provides an estimate of how many calories a person should eat each day to maintain, lose, or gain weight.

Quick Summary

  • Calorie calculation helps to maintain, lose, or gain weight.
  • It is used to estimate daily caloric needs and track caloric burn.
  • The history of calorie calculation dates back to the 19th century.
  • Calorie calculation is linked to many aspects of daily life, especially diet and health.

A Brief History of Calorie Calculation

The concept of calories was first introduced in the mid-19th century by physicist and chemist, Nicolas Cl?ment, before becoming popular in the 20th century as a standard method of measuring food energy.

The Link Between Calorie Calculation and health needs

Calorie calculation is directly linked to daily energy expenditure, nutrition, bodyweight management, athletic performance, and overall health. Understanding your personal caloric needs can lead to more successful diet planning, improved physical performance, and better health outcomes.

Understanding calorie calculation is crucial in everyday life. It provides the knowledge we need to consume the right quantity and quality of food needed for our bodies to operate optimally.

Common Reasons to Calculate Daily Calories

Here are a few reasons why someone might want to calculate their daily calories:

  • Weight management: It helps you either lose or gain weight safely.
  • Nutrition: Allows for better meal planning and ensuring you meet nutritional needs.
  • Physical Fitness: Helps in improving endurance and performance in sports or other physical activities.
  • Health: Understanding calories is essential for managing certain health conditions like diabetes, heart diseases etc.

Do You Know?

Did you know that the largest recorded daily caloric intake was by Olympic swimmer Michael Phelps, who reportedly consumed 12,000 kcal a day during intense training? On the other hand, the smallest adult diet can be the medically supervised “Very Low Calorie Diet”, which may be as low as 800 kcal. Calorie counting is now a multi-billion dollar industry, with fitness trackers and diet apps commonly used to help people manage their calorie inflow and outflow.

The more you understand about calorie calculation, the better you can tailor your diet to meet your personal health and fitness goals.

Remember that calorie calculation is simply a tool and not a one-size-fits-all solution. Every person is unique and may have different caloric needs due to factors like age, gender, metabolic rate, physical activity level, and health status. Always consult with a healthcare provider or nutritionist before making significant changes to your diet or exercise regimen.
