Calorie is a unit of energy. Here, it refers to the energy we absorb from the food and drinks that we intake. They are essential for human health. They can put you on the range of either overweight or underweight. The key is taking in just the right amount. As humans, we need the energy to survive and go on about our work. Our body needs calories to survive. Each one has a different metabolic rate – the rate at which our body burns energy. We should always be aware of the calories consumed to maintain consistent fitness levels and stay healthy. The suggested intake depends on various factors- lifestyle, age, height, weight, sex, body shape, etc. 
Also, there are a lot of calculators and tools readily available online. But if you want to do it yourself, here’s how to calculate the right calorie intake.

How to calculate calorie intake:

1. Calculate your BMR

BMR is the number of calories your body burns when it is at rest, i.e., when not moving. It mainly depends on your age, height and weight. This is a simple formula to calculate an approximate number.

MEN	WOMEN
BMR= 65 + (6.2 x weight in pounds) + (12.7 x height in inches) – (6.8 x age in years)	BMR= 655 + (4.3 x weight in pounds) + (4.3 x height in inches) – (4.7 x age in years)

2. Calculate your daily activity level

There are 4 activity levels:

• Sedentary – Little or no physical activity- 1.2
• Light Level – Physical activity for 1-2 days a week- 1.375
• Moderate Level – Physical activity for 3-5 days a week- 1.55
• Very Active Level – Physical activity every day- 1.725

3. Calculate the number of calories to maintain current weight

Once we know how many calories we need to intake to maintain our current weight, we can decide what to do to either gain or lose weight accordingly.

Number of calorie intake = BMR * Daily Activity Level factor.

NOTE: To lose 1 pound per week, subtract 500 calories from the number of calorie intake. To stay fit and strong, regulate your calorie intake and your daily exercise.

How to calculate calories in food

Each food item has its own number of calories. To calculate, we should know the exact amount of protein, fat and carbs in the food or drink that is being consumed.  There are two ways of calculating the number of calories in food:

1. Add each of the calorie values from each nutrient

Each macro-nutrient should be multiplied by its caloric equivalent. 1g of protein contains about 4 calories. 1g of carbohydrates has 4 calories, and 1g of fat has 9 calories.

2. Use a calorie calculator

We can use a guide or look up online to find the number of calories for a particular food of a precise quantity. Here’s a list of a few essential Indian foods and their relevant number of calories.
