Calories are units of energy which are found in all food you eat and everything you drink, no matter how large or small the food contents, they are there – from water to your Big Mac, they all have calories. They are your fuel during the day and play a part in ensuring the daily functions of your body and they keep you full during the day.

Calories are important as they ensure that you are fuelled during the day with them being in all food and beverages, knowing them will help calculate how much you are eating in all that you consume, how much you should be eating and ensure that you can eat according to your physique and fitness goals, because you burning energy every day to breathe, walk, sit etc. the fact they are found in everything you consume, it ensures that your energy can be replenished where it is required.


Calorie counting is a pivotal basic in ensuring that your food intake can be managed, some people do it and some don’t, some rely on it as a learning curve in knowing how much food you should be eating and how much of certain foods you should be eating, but others listen to their body’s and take note of what changes occur when they consistently eat in certain ways or certain things. This means that whether or not you count calories, it should all depend on what works for you according to your health and fitness goals.

Counting calories is something that I had discovered quite recently and feel it has proven to be a great difference maker in all gains and losses I’ve made on my body, the calories of food can be found at the back of the packaging by the nutritional information section where energy is written, it usually written in kilojoules (kJ) to convert it to kilocalories (kcal) you multiply by 0,239006.

There is a formula that can be used to count the number of calories that are required by your body no matter what your goals are, it is dependent on your body composition, your habits and your level of activity during the week, it will ensure that you eat according to your goals on a weekly basis to achieve the body that you desire – you will calculate how much energy your body uses daily – Total Daily Energy Expenditure (TDEE) = Basal Metabolic Rate (BMR) x Activity Factor: :

1. Calculate Basal Metabolic Rate (The amount of energy consumed at rest)

Women BMR = 655 + (9.6 X weight in kg) + (1.8 x height in cm) – (4.7 x age in years)

Men BMR = 66 + (13.7 X weight in kg) + (5 x height in cm) – (6.8 x age in years)

2. Activity Factor (weekly activity)

Level of Activity Activity Value TDEE Calculation
Sedentary Little or 0 exercise/desk job TDEE = 1.2 x BMR
Lightly active Light exercise/ sports 1–3 days/ week TDEE = 1.375 x BMR
Moderately active Moderate exercise, sports 3–5 days/week TDEE = 1.55 x BMR
Very active Heavy exercise/ sports 6–7 days/week TDEE = 1.725 x BMR
Extremely active Very heavy exercise/physical job/training 2x/day TDEE = 1.9 x BMR
