Daily Calorie Requirements

Daily Calorie Requirements

What are your daily calorie requirements? In short, your daily calorie requirements are the calories required to maintain your physiological health. We all need a specific amount of calories each day. The calories provide us with enough energy to sustain our lives. Most of us eat more than enough to maintain our physiological health. Therefore, most people are more interested in their daily calorie requirements for maintaining, losing, or gaining weight.

Once we reach our weight loss goal, we must maintain our daily calorie requirements to keep the same weight. Nevertheless, our daily calorie requirements will vary significantly from one person to the next.

But, generally speaking, men should eat about 2700 calories per day while women should eat about 2000 calories per day. To give you a better frame of reference, this generality is provided based on the average height of a man and a woman being 5’8 and 5’4, respectively. Therefore, gender and height are clearly factors affecting daily calorie requirements.

Yet, there is more.

Our daily calorie requirements vary based on our gender, height, age, weight, body mass index and level of activity. A calorie is a unit of energy. Therefore, the calories we get from different foods provide us with needed energy. Most of the calories we need are used for energy to keep our heart, lungs, brain, and more functioning properly.

Personal Example:

I am 5’8 tall. For my age, when I am physically active I need 2576 calories each day to maintain my weight. To lose weight, while active I must eat 2061 calories per day. When I get little or no exercise, I can only eat 1627 calories per day to maintain my weight. With no exercise, I can only eat 1302 calories per day to not gain or lose any weight. So, if I went on a “general” 2,000 calorie diet recommended for women, I would be anorexic thin. Therefore, each individual must calculate their daily calorie requirements! Please do not just assume you need 2,000 calories each day. You may find that you need more or less.

How Many Calories Do I Need?

Once you choose a low carb diet plan. You can determine your daily calorie requirements using a calorie calculator. Then, once you determine your daily calorie requirements, you must implement a calorie deficit in order to lose weight. Both the maintenance and caloric deficit can be determined with the calorie calculator. Next, you can learn about the role of macronutrients in the body.

As you lose weight, you must continue recalculating your daily calorie requirements until you reach your weight loss goal. Once your weight loss goal is realized, you will not need to keep adjusting your daily calorie requirements. At this point, you will be eating your daily calorie requirements to maintain your achieved weight loss goal.


Clearly, a low carb diet plan is by no means a “one-size” fit all plan. Additional factors that must be consider are your personal health problems and limitations. Things like low carb, low sodium and low sugar requirements must be factored into your low carb meal plans. This concludes our post on daily calorie requirements.
