How Much Calorie Do I Need Per Day?

The calories required per day depend on several factors, including metabolism, age, height, lifestyle, degree of physical fitness, and the type and quantity of food you eat. 

The average recommended daily calories for men and women is 2000 and 2, 500/day, respectively.

What are Calories?

Calorie denotes a unit of energy that you derive from the food and drinks you consume and the amount of energy you use to perform various physical activities. 

The more calories a food product has, the more power/energy you can get from consuming it. And when your calorie count exceeds the range of calories your body needs, your body deposits those additional calories as fat.

The calorie count of different food items varies. It means that the three macronutrients, carbohydrates, proteins, and fats your body needs, do not have the same number of calories. Here is a breakdown of calories:

Calories per gram in macronutrients

  • Carbohydrate: 4 calories/gram
  • Protein: 4 calories/gram
  • Fat: 9 calories/gram

For example, you can get 150 calories by munching on a candy bar or 30 cups of lettuce. The bottom line is to understand that all calories are not the same. It will help you make better dietary choices.

How many calories should you eat on average? 

The answer to this question will vary from person to person, depending on various factors, such as height, weight, age, metabolism, overall health, and physical fitness. The one-size-fits-all approach does not work here. An example will help you understand this. 

If you want to lose weight, you should keep your calorie consumption 500 calories less than your body needs. This practice will help you maintain your current body weight in the long run. The calories you should consume in a day varies.


  • Moderately active women between 26–50 years need around 2,000 calories/day.
  • Active women (who walk around 5 kilometers a day) will likely need 2,200 calories/day.
  • Women in their early 20s need more calories, around 2,200 calories/day or more, to manage their weight. 
  • Women who are more than 50 years old need fewer calories, around 1,800 calories/day.
  • If you are pregnant or breastfeeding, the above chart might not be suitable for you. Discuss your options with your doctor.


  • Moderately active men between 26–45 years need 2,600 calories/day.
  • Active men (who walk around 5 kilometers a day) need about 2,800 to 3,000 calories/day.
  • Men between 19 to 25 years need approximately 2,800 calories/day.
  • Men between 46–65 years need 2,400 calories/day.
  • Men above the age of 66 will likely need 2,200/day.


  • The calorie requirement of children varies widely. 
  • While an average toddler may need 1,200 to 1,400 calories a day, moderately active teenagers will likely require 2,000 to 2,800 calories a day.

Calories Required Per Day: Calorie Intake

Whether you want to gain, lose, or maintain your current body weight, counting calories is crucial. The pointers given below will help you understand your calorie requirements according to your specific needs. 

  • Losing weight: Generally, dietary recommendations state that you need to reduce your total calorie intake by 500 calories per day if you want to lose one pound a week. It means if you need 2,000 calories/day, you should reduce it to 1,500 calories/day to lose 1 pound a week. However, as losing weight is a slow process, it is highly advisable to be patient and work with your dietician to find a suitable diet plan for you.
  • Gaining weight: If you want to gain weight, try not to do it yourself and seek professional help. An expert dietician can chalk out a weight-gain diet plan according to your body’s needs to help you healthily gain weight.
  • Maintaining a healthy weight: Your daily calorie intake for maintaining a healthy weight depends on various factors. It includes the following:
  • How old are you?
  • How physically active are you?
  • What is your BMI or Body Mass Index (ideally, the BMI for women is 21.5 and men is 22.5)? 

How to reduce calorie intake?

Some of the most effective ways to reduce your calorie intake include:

  • Try to avoid sugary beverages and fruit juices
  • Include more protein in your diet
  • Keep yourself adequately hydrates
  • Make sure to exercise regularly
  • Cut on your carbohydrate (refined) intake
