EER Calculator: Are You Overeating or Undernourished?

“Welcome to the EER Calculator! This tool helps you estimate your daily energy needs based on different factors like age, gender, weight, height, and activity level. 


Just enter your details and let the EER calculator give you an idea of how many calories you might require each day.” Feel free to adjust the introduction to suit your context.

Today, we will talk about some interesting topics that are very important for your health. It is called “Estimated Energy Requirement”. Relax, don’t worry we’ll make it into simple words so you can understand it easily.

What is EER?

Estimated Energy Requirement is similar to how much fuel a car needs to move each day to maintain its proper performance. 
This fuel, which can be measured in something called calories, comes to you in the form of the food you consume.

Three main things affect how much energy your body needs each day: physical activity, the food you eat, and the climate you’re in. Among these, physical activity has the biggest impact, making up 15-30% of your total energy needs. You can control this factor to some extent—more activity means more energy needed, and less activity means less energy required.

Your diet matters too, especially the types of nutrients in your food. The thermic effect of food, which is how much energy your body uses to digest and process what you eat, makes up 10-13% of your total energy expenditure. Depending on what you eat, this value can drop to 6 or 7% with very strict diets like Keto, although those can be tough to stick to.

The climate you’re in also plays a role, but it’s something you can’t control much. Hot weather can increase your energy needs by 5-20%, and cold weather has similar effects because your body uses more energy to stay warm.

Your body size and composition matter too. Our EER calculator shows this when you input your gender and age. Generally, women, with more body fat and less muscle mass, burn less energy compared to a man of the same weight. Age is a factor too—older people usually use less energy than younger ones of the same weight and gender. You can see this difference by changing the age in our online estimated energy requirement calculator.

First Step when Estimating Your Daily Energy Requirement

The initial step when estimating your daily energy requirement is to consider your level of physical activity. Physical activity is a significant factor that influences your energy needs. The amount of energy you burn is closely tied to how active you are throughout the day.

To determine your daily energy requirement, you can start by assessing your physical activity level. Consider how much time you spend engaged in various activities, from exercise to daily tasks. This assessment will help categorize your activity level, which is crucial in estimating the calories your body needs to function optimally.

Remember that physical activity is just one component of the equation. Other factors, such as your diet composition, the climate you’re in, and your body size and composition, also play roles in determining your overall energy requirements. However, identifying your level of physical activity is often the first and fundamental step in this estimation process.

How does the EER Calculator work?

The Estimated Energy Requirement calculator is a device created to estimate how many calories or energy a person needs to consume daily to maintain their present body weight. 
EER Calculator bases its calculations on numerous variables, including age, gender, level of physical activity, and basal metabolic rate. 
This formula helps people precisely adjust their dietary intake to fulfill their energy needs.

The EER calculator works by performing a series of computations that consider the following significant factors:
BMR stands for basal metabolic rate, which is the amount of energy used by a person to keep their basic biological functions like breathing and circulation going while they are at rest. Age, gender, weight, and height are influencing factors.
Physical Activity Level (PAL): PAL describes how much physical activity a person does each day. It can be extremely active (intensive exercise and physical labor) or sedentary (minimum physical activity).

The general formula for calculating energy requirement is as follows:
To break down the process:
Calculate the BMR using a formula like the, which considers gender, weight, height, and age.
Determine the appropriate PAL based on the person’s activity level. PAL values are typically categorized as sedentary, lightly active, moderately active, active, or very active.

Multiply the BMR by the chosen PAL to obtain the estimated energy requirement (EER) for that individual.
It’s important to note that the EER provides an estimate, and individual variations may apply. 
The EER calculator offers a useful starting point for understanding daily energy needs, which is crucial for weight maintenance or achieving specific fitness goals.

EER Formula

EER=BMR×Physical Activity Factor×Thermic Effect of Food Factor

(Basal Metabolic Rate) 

It represents the number of calories your body needs at rest to maintain basic physiological functions, such as breathing and maintaining body temperature. 
It is typically calculated using equations like the Harris-Benedict equation, which takes into account age, gender, weight, and height.

Physical Activity Factor 

This factor accounts for the calories burned through various physical activities, ranging from sedentary (little to no exercise) to highly active (intense physical activity or regular exercise).

Thermic Effect of Food Factor 

The thermic effect of food represents the energy expenditure associated with digesting, absorbing, and processing food. It typically accounts for a certain percentage of the total caloric intake.

How to use the EER calculator effectively

Input accurate personal details such as age, gender, weight, height, and activity level. The calculator applies the formula and adjusts it according to the chosen activity level.

The result provides an estimate of the daily calories needed to maintain current weight.
It’s worth mentioning that the EER calculator serves as a guide and should be used in conjunction with sound nutritional knowledge and advice from healthcare professionals or registered dietitians.

EER=BMR×PAL

How Do We Figure Out Energy Requirements?

Imagine your body as a machine. Even when taking a rest or just lying down and not moving, this machine works continuously. It needs a certain quantity of calories to perform its basic purposes. 
It is referred to as Your “Basal Metabolic Rate”. It’s the calories your body needs for the essential stuff like breathing, pumping blood, and other things you don’t even notice.

But wait it doesn’t end here. Your body is more than just an inflexible machine. You move about, play, and engage in various activities. 
So, we need to add more calories to the BMR to cover the energy you use while moving around. This is your “Physical Activity Level.”

The EER (Estimated Energy Requirement) calculator is a useful tool for individuals looking to understand their daily energy needs based on factors like age, gender, activity level, and weight. This calculator aids in tailoring nutrition plans to meet specific energy requirements for maintaining, gaining, or losing weight effectively.

For those engaged in more specialized dietary approaches, such as carb cycling, integrating tools like the Carb Cycle Calculator alongside the EER calculator can provide a comprehensive strategy. The Carb Cycle Calculator assists individuals in optimizing their carbohydrate intake on different days of the week, aligning with their fitness goals.

By combining these calculators, individuals can tailor both their overall caloric intake and macronutrient distribution, ensuring a more precise and personalized approach to their dietary and fitness endeavors.

In addition, some calories are used by your body to digest the food you eat. This energy is necessary to digest the food and all of its healthy ingredients. This is referred to as the “Thermic Effect of Food.”
Finally, your body may occasionally need a little extra energy if you’re unwell or doing something extremely difficult. This procedure is referred to as “adaptive thermogenesis.”

Why is EER Important?

Knowing your energy requirements is like having a secret formula for staying healthy. You give your body exactly the type of energy it requires to function efficiently when you eat the appropriate amount of food to meet your EER. 

In the pursuit of a healthy lifestyle, understanding and managing total energy expenditure is essential. 
Total energy expenditure (TEE) represents the total number of calories your body needs to maintain its current weight.

Overeating can lead to weight gain if you consume more calories than your energy requirements. Additionally, you might lose weight if you eat less than your required energy.

Using Energy Requirements in Real Life

Imagine having a handbook that details the recommended daily dietary intake. Knowing your required energy is similar to that. 
You can plan your meals and snacks around it. You won’t eat too much or too little food; just the right amount for your body.
You may stay active, feel well, and have the energy to accomplish everything you enjoy as a result.
