how to calculate your daily calorie intake

”You cannot out-exercise a bad diet”. A golden rule in life and in fitness.

Eating the right amount of calories for your body is extremely important. Eating too much or too little can affect your fat loss results.

So, how do you calculate your ideal calorie intake?

How to know what is right for you and your body?

Below, I will show you formulas that work for calculating your Basal Metabolic Rate (BMR) & Total Energy Expenditure (TEE)

These are fancy terms for how many calories you need to just stay alive and how many if you’re remotely or moderately active/working out :) )

You can calculate both BMR & TEE to get your daily ideal calorie intake using the calculator below.

If you want to know more details read below my breakdown of formulas and more details about what BMR & TEE mean for you.

Note: Please remember that these formulas may not be exactly right for everyone but they are a pretty good indication.

Also, the formulas are for women only. There are different formulas for men.


What is BMR?

Basal Metabolic Rate is the number of calories required to keep your body functioning at rest.

Meaning if you lie in bed all day and do nothing, this is the number of calories your body will spend just to keep everything running properly.

BMR is also known as your body’s metabolism; meaning that any increase to your metabolic weight, such as exercise, will increase your BMR

BMR Formula

This formula is the revised Harris-Benedict equation. It can get a bit confusing, so stay with me!

The formula is: 447.593 + (9.247 x body weight (kg)) + (3.098 x height (cm)) – (4.33 x age in years)

My weight is around 52kgs, my height is 167cm and my age is 27 years. So here’s my example.

  • 447.593 + (9.247 x 52) + (3.098 x 167) – (4.33 x 27)
  • = 1329 calories

This means that if I were to lie in bed all day and do absolutely nothing, my body would use up 1329 calories per day.

What is TEE?

Total energy expenditure is the amount of energy that a person needs to carry out all physical functions (breathing, digesting food, exercising). 

Energy is measured in calories, and your total energy expenditure (TEE) is the number of calories you burn each day.

TEE Formula

Multiply your BMR by the TEE value below, based on your activity level.

Little to none1.2
Light (1-3 days)1.375
Moderate (3-5 days)1.55
Heavy (6-7 days)1.725
Very heavy (twice daily)1.9

I exercise 6 times per week for about an hour, but usually 2 of these sessions are low intensity cardio such as power walking.

I would considerate myself in the moderate range so I will multiply my BMR (1329) by 1.55.

Total Energy Expenditure = 1329 x 1.55 = 2060 calories.

This means that if I were to exercise 5 times per week, my body would burn 2060 calories per day.

Usually, for fat loss, you should be in a daily calorie deficit of around 200-500 calories.

A more severe calorie restriction will result in a more severe fat loss.

However, any form of dieting and calorie restriction will reduce your metabolic rate, so just keep that in mind (also remember that resistance training increases your metabolic rate).

I like to be at a 300 calorie deficit because I don’t get as hungry.

Therefore, my ideal calorie intake should be 2060 – 300 = 1760 calories.

But if I were to be at the 500 calorie deficit, my ideal calorie intake would be 2060 – 500 = 1560 calories.


If you are trying to maintain your weight, you would just stick to your total energy expenditure, which would be 2060 calories for me (which we worked out in step 2).


If you are trying to gain weight, you would want to eat more than 2060 calories.

I would also advise gaining weight in a slow and steady manner- so up your calories for 500 a day for gaining weight slowly.

I hope this makes sense and has answered your questions on how to calculate your daily calorie intake! xx

    I want to lose fat but maintain my weight (build muscles to compensate). I’m an endomorph and to maintain my weight I have to eat around 1900 calories, should I go for a slight caloric deficit diet so 1600 calories or eat 1900 calories? I am scared eating a maintenance calories might lead to weight gain especially as I am an endomorph. But having eaten 1600 calories for few months I’ve lost weight and I don’t wish to lose any more weight. I aim for fat loss. I am doing hiit, light resistance training and power walking. Just need help with my diet!

      Hi lovely,

      You can eat for maintenance if you don’t want to lose more weight. To serve as a reference, you can also calculate your ideal daily calorie intake through this link. :)

      If you’re an endomorph, in order to not gain unwanted bulkiness, I would advise that you stick to light-resistance workouts and avoid doing HIIT.

      I hope that helps. xx

    Hi !!
    Thank you answer ! It’s really helping :)
    Some weeks, I don’t have a lot of time, so I use to skip resistance training … :S
    If I do only the 10 000 steps a days, should I choose “ligth” or stay in “moderate” activity level when calculating my ideal daily calories intake ?
    Have a lovely day, and thank you again !

      Hi lovely,

      Thanks for reaching out!

      If your goal is to slim down your legs there are 3 steps you should follow – do the right type of cardio, do bodyweight resistance training, and adjust your diet for weight loss. Removing one from your routine won’t help you achieve your goals faster so we still encourage that you incorporate light-resistance workouts in your routine and focus more on nutrition.

      In the meantime, if you could only focus on power walking then you can choose ‘light’ as your activity level.

      I hope that helps. If you have more questions, feel free to email us at info@rcahaelattard.com
