What Is My EER (Estimated Energy Requirement) ?

Your Estimated Energy Requirement (EER) is a vital piece of information that can help you maintain a healthy lifestyle. By understanding your body’s daily caloric needs, you can make smarter choices about your diet and exercise routine. This article will explain what EER is, how it’s calculated, and how you can use it to optimize your health and fitness journey.

Understanding Estimated Energy Requirement (EER)

EER is a measurement of the number of calories your body needs to perform essential functions such as maintaining body temperature, growing, and repairing cells, as well as fueling physical activities. Your EER is influenced by various factors, including age, gender, weight, height, and activity level.

Knowing your EER can help you make informed decisions about your daily caloric intake, ensuring that you consume enough energy to maintain a healthy weight, build muscle, or lose fat, depending on your fitness goals.

How to Calculate EER – Estimated Energy Requirement Formula ?

To calculate EER, you need to consider your age, gender, weight, height, and physical activity level. The Institute of Medicine (IOM) provides a set of equations based on these factors, which can be used to estimate your daily caloric needs.

EER Formula is as follow as

Estimated Energy Requirement ( EER ) = BMR* PA

Here’s a step-by-step guide to calculating your EER:

1. Determine your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation:

• For men: BMR = (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) + 5
• For women: BMR = (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) – 161

2. Calculate your Physical Activity (PA) level:

• Sedentary: PA = 1.0
• Low active: PA = 1.12 (for men) or 1.14 (for women)
• Active: PA = 1.27 (for men) or 1.27 (for women)
• Very active: PA = 1.54 (for men) or 1.45 (for women)

3. Multiply your BMR by your PA level to get your EER:

                              EER = BMR x PA

Example #2 :-

Scenario: Sarah is a 30-year-old female who wants to lose weight. She weighs 65 kilograms and is 160 cm tall. She describes her physical activity level as ‘moderately active’ because she engages in regular cardio and strength training workouts.

Now, we’ll calculate Sarah’s EER using the same EER formula as before:

EER = 662 – (9.53 × A) + PA * [(15.91 × W) + (539.6 × H)]

Here are the parameter values for Sarah:

• Age (A): 30 years
• Weight (W): 65 kilograms
• Height (H): 160 cm
• Physical Activity Level (PAL) for ‘moderately active’ (as per the table): 1.55

Now, let’s calculate Sarah’s EER:

EER (kcal/day) = 662 – (9.53 × 30) + 1.55 * [(15.91 × 65) + (539.6 × 1.60)]

EER (kcal/day) = 662 – 285.9 + 1.55 * [1035.15 + 862.56]

EER (kcal/day) = 662 – 285.9 + 1.55 * 1897.71

EER (kcal/day) = 662 – 285.9 + 2937.185

EER (kcal/day) = 3313.285

In this scenario, Sarah needs to eat approximately 3,313.29 calories per day to maintain her current weight. Remember that if her goal is to lose weight, she should create a calorie deficit by consuming fewer calories than her EER, combined with a suitable exercise plan.

 ^{Using Your EER for a Healthier Lifestyle}

Once you have calculated your EER, you can use this information to tailor your diet and exercise plan to your specific needs. Here are some tips on how to use your EER effectively:

Maintain a healthy weight: If your goal is to maintain your current weight, aim to consume the same number of calories as your EER. Monitoring your caloric intake can help prevent weight gain or loss.

Lose weight: To lose weight safely, you should aim for a calorie deficit of 500 to 1,000 calories per day, which can lead to a weight loss of 1-2 pounds per week. Make sure to adjust your EER accordingly and never consume less than 1,200 calories per day for women or 1,500 calories per day for men.

Gain weight or build muscle: If your goal is to gain weight or build muscle, you’ll need to consume more calories than your EER. Aim for a calorie surplus of 250 to 500 calories per day, and adjust your macronutrient intake to prioritize protein for muscle growth.

Balance your macronutrients: In addition to caloric intake, it’s essential to pay attention to the quality of your diet. Make sure to consume a balanced mix of carbohydrates, proteins, and fats to fuel your body efficiently. A general guideline is to allocate 45-65% of your daily calories to carbohydrates, 10-35% to protein, and 20-35% to fat.

Adjust for changes in activity level: Your EER is influenced by your activity level, so if you become more or less active, your caloric needs will change. Monitor your activity levels and adjust your EER accordingly to ensure you’re providing your body with the energy it needs.

Monitor and reassess: As you progress in your fitness journey, your body composition, weight, and activity levels may change. Reassess your EER regularly to ensure that you’re staying on track with your health and fitness goals.

Understanding and calculating your Estimated Energy Requirement (EER) is an invaluable tool for maintaining a healthy lifestyle. By taking into account factors such as age, gender, weight, height, and activity level, you can determine your daily caloric needs to achieve your fitness goals. Use your EER to make informed decisions about your diet and exercise plan, and remember to adjust it as your body and lifestyle change. With this knowledge, you’ll be better equipped to make healthier choices and reach your health and fitness goals.

What are BMR , RMR & TEE ?

Understanding your body’s energy needs is crucial for maintaining a healthy lifestyle, achieving weight loss, or gaining muscle. Various measurements can help you estimate your daily caloric requirements, each taking into account different factors and serving specific purposes. This article will introduce you to four essential measurements of energy needs: Basal Metabolic Rate (BMR), Resting Metabolic Rate (RMR), Total Energy Expenditure (TEE), and Estimated Energy Requirement (EER).

Basal Metabolic Rate (BMR)

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain its basic functions while at rest. These functions include breathing, circulation, cell production, nutrient processing, and more. BMR is influenced by factors such as age, gender, weight, and height.

Calculating your BMR can provide you with a baseline understanding of your daily caloric needs. Several formulas can be used to estimate BMR, with the Mifflin-St Jeor equation being one of the most popular and accurate.

Resting Metabolic Rate (RMR)

Resting Metabolic Rate (RMR) is similar to BMR, as it also measures the calories your body needs to perform essential functions while at rest. However, RMR takes into account the calories burned during digestion and the absorption of nutrients, making it slightly higher than BMR.

While both BMR and RMR provide valuable insights into your body’s energy needs, RMR is considered a more practical measurement, as it better reflects the calories you burn during a typical day of rest.

Total Energy Expenditure (TEE)

Total Energy Expenditure (TEE) takes your energy needs a step further by considering the calories you burn during physical activities. TEE is the sum of your RMR, the thermic effect of food (TEF), and the energy expended during physical activity (PA).

TEE provides a more comprehensive understanding of your daily caloric requirements, as it considers your lifestyle and activity level. To maintain your current weight, your caloric intake should be equal to your TEE.

Estimated Energy Requirement (EER)

Estimated Energy Requirement (EER) is an estimation of the number of calories you need to consume daily to maintain your current weight, taking into account factors such as age, gender, weight, height, and activity level. EER is a practical and useful measurement for tailoring your diet and exercise plan to your specific needs.

Calculating your EER involves determining your BMR and multiplying it by a Physical Activity (PA) level coefficient, which ranges from sedentary to very active.

How to Use These Measurements for a Healthier Lifestyle

Understanding these various measurements of energy needs can help you optimize your health and fitness journey. Here are some ways to utilize these measurements effectively:

1. Calculate your BMR, RMR, or EER to understand your baseline energy needs.
2. Determine your TEE to account for your daily activities and lifestyle.
3. Monitor and adjust your caloric intake based on your goals, such as weight loss, muscle gain, or weight maintenance.
4. Reassess your energy needs as you progress in your fitness journey, considering changes in weight, body composition, and activity level.

Does EER depends upon Your Physical Activities ?

Your Estimated Energy Requirement (EER) is a crucial factor in understanding your body’s daily caloric needs. But does EER depend on your physical activities? The short answer is yes. Your EER takes into account various factors, including age, gender, weight, height, and activity level. This article will explain the relationship between EER and physical activities, and how you can adjust your EER to suit your fitness goals and lifestyle.

How Physical Activities Influence EER

Physical activities play a significant role in determining your EER. The more active you are, the more energy your body requires to support your daily activities. As a result, your EER will be higher for those who lead active lifestyles compared to those with sedentary lifestyles.

Physical activities are generally categorized into four levels:

1. Sedentary: Little to no exercise, primarily sitting or lying down during the day.
2. Low active: Light activities such as casual walking or stretching, and engaging in some form of exercise 1-3 times a week.
3. Active: Moderate to intense activities like jogging, swimming, or dancing, with regular exercise 3-5 times a week.
4. Very active: Intense and prolonged physical activities, such as competitive sports or daily vigorous exercise.

To account for the impact of physical activities on EER, different Physical Activity (PA) level coefficients are used when calculating your daily caloric needs.

Adjusting Your EER Based on Physical Activities

As your physical activity level changes, so does your EER. It’s essential to adjust your EER accordingly to ensure that you’re providing your body with the energy it needs. Here’s how to adjust your EER based on your activity level:

1. Calculate your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation.
2. Determine your PA level coefficient based on your current activity level.
3. Multiply your BMR by your PA level coefficient to obtain your EER.

If your activity level changes, reassess your PA level coefficient and recalculate your EER to accurately reflect your new energy needs.
