Being on the lookout for your calorie intake every time you eat can be challenging without assistance. Whether you started dieting a few days ago or have been in this venture for months, taking a strong look at your calorie intake and how many calories you burn can be a game-changer.

When we start dieting, we often fail as we do not measure the calorie intake. A Calorie Calculator will set you up for success when you start dieting. Today, we will take a deep dive into calorie calculators and how they can assist you in staying in shape.

What is a Calorie Calculator
Jump Tag Icon

A Calorie Calculator is a tool that helps you estimate the amount of calories you need to take in daily to achieve certain goals like maintaining, losing, or gaining weight. The following are considered when calculating calories:

You can use the calculator mentioned on the American Cancer Society’s website to calculate your daily caloric requirement.

In general, the parameters required for the calculation are as follows:

Note: This calculator provides a close estimation of your Basal Metabolic Rate (BMR) and not the exact value. 

The process begins with users inputting their basic information into the Calorie Calculator, then selecting their activity level, which helps calculate the Basal Metabolic Rate (BMR)—the calories required to sustain vital bodily functions at rest.

Once you have estimated BMR, you can calculate your daily caloric need by multiplying it with a value that depends on your activity level. This is illustrated in the following table:

Criteria

Lifestyle

DailyCaloric Need

Little or no exercise

Sedentary

BMR X 1.2

Exercise one to three times per week

Lightly Active

BMR X 1.375

Exercise four to five times per week

Moderately Active

BMR X 1.55

Daily exercise or intense exercise three to four times per week

Very Active

BMR X 1.725

Intense exercise six to seven times per week

Extra Active

BMR X 1.9

 

This BMR is then made to differ by the user's activity level condition to accomplish the Total Daily Energy Expenditure (TDEE), which is the amount of calories necessary to continue to maintain the original weight. Whether it’s for weight loss, maintenance, or gain, the calorie calculator adjusts the calories in the TDEE to result in either a calorie deficit or surplus. 

This finally leads to a recommendation of daily calories for users, helping them manage a diet well and move towards their health and fitness goals. A calorie calculator is a practical way to get a handle on your nutritional needs and how to make informed dietary choices.

What is Calorie?
Jump Tag Icon

A calorie is a unit of energy. When we count calories, we essentially count the energy derived from a particular food item. We derive calories from the carbohydrates, proteins, and fats we consume in our diet. Calories in our diet mainly come from carbohydrates, proteins, and fats, each contributing a different concentration of calories.

 

1. Hourglass
Jump Tag Icon

The hourglass figure is characterised by curvy proportions, with the bust and hips of similar size and a well-defined waist that creates a naturally balanced silhouette. This shape is often considered highly desirable for its symmetry. Clothes that emphasise the waist, such as fitted dresses or tops with belts, beautifully enhance the natural curves of the hourglass figure.

2.Protein
Jump Tag Icon

Proteins are needed to build and repair tissues, make enzymes and hormones, and help to keep the entire body functioning. Each gram of protein also gives about four calories. Meat, fish, eggs, dairy products, beans, and legumes are protein sources. Sometimes proteins are complete (contain all the essential amino acids) and sometimes incomplete.

3.Fat
Jump Tag Icon

Fats are a concentrated source of energy, with about nine calories per gram, twice as many calories as carbohydrates or proteins. They play a vital role in absorbing fat-soluble vitamins and supporting cell growth. Oils, butter, nuts, seeds, and fatty fish are common sources of fats. There are three main types of fats - saturated, unsaturated (monounsaturated and polyunsaturated), and trans fats. Unsaturated fats are the healthiest of all.

How Many Calories Do You Need?
Jump Tag Icon

The amount of calories you need daily depends on factors like age, gender, weight, height, and physical activity level. An average adult male needs about 2,500 calories daily, and an average adult female needs about 2,000 calories daily to maintain weight. 

However, calorie needs vary widely depending on your lifestyle and metabolic rate. For example, athletes or people with highly active lifestyles may need more calories to fuel their activities, while others with sedentary lifestyles may need fewer calories. 

Also, the calories required will depend on specific goals, such as weight loss, weight maintenance, or weight gain. A Calorie Calculator can help you to consider these variables and give you a personalised recommendation based on your health and fitness goals.

Health Impacts of Following a Very Low-Calorie Diet
Jump Tag Icon

A diet that's too low in calories can have some serious health implications. While it does cause rapid weight loss, it can also cause several issues that can affect your overall well-being. Below are some key drawbacks:

Nutritional deficiencies
Jump Tag Icon

Excessively restricting calories may not meet the need for essential nutrients, vitamins, and minerals. Deficiencies can occur that affect many bodily functions and overall health.

Metabolic slowdown
Jump Tag Icon

A long and significant calorie deficit can slow your metabolism. That means your body burns fewer calories at rest, making it more difficult to lose weight and more likely to regain it when you return to a normal diet.

 

Fatigue and weakness
Jump Tag Icon

A lack of energy, fatigue, and weakness can occur if you don't consume enough calories. It can make it difficult to do everyday things, like getting out of bed or driving your car.

 

Mood changes and mental health issues
Jump Tag Icon

Insufficient calories can affect your mental health, causing you to feel moody, irritable, and depressed. Without calories, the brain can't get the nutrients it needs to work properly.

Digestive issues
Jump Tag Icon

  • Constipation: Water is crucial for digestive processes. Inadequate water intake slows down bowel movement, causing hard stools and constipation.
  • Acid Reflux and Heartburn: Low water intake can also increase acidity in the stomach, leading to acid reflux and heartburn symptoms.

Muscle loss
Jump Tag Icon

When you don't consume enough calories, your body may begin to use muscle for fuel. If you don't use your muscles, you can lose them, and that can affect your strength and how you look.

 

Increased risk of gallstones
Jump Tag Icon

Financial calculations involve numbers, formulas, and variables prone to human error. Without the accuracy and efficiency of a financial calculator, the risk of making mistakes increases. These errors can have significant consequences, such as incorrect budgeting, overestimating savings, underestimating expenses, or miscalculating investment returns.

Long-term health risks
Jump Tag Icon

If you follow a too-low-calorie diet over a long period of time, you can develop long-term health risks such as weakened bones, reduced fertility, and impaired immune function.

Making The Most of Our Calorie Calculator For Weight Management
Jump Tag Icon

Keeping track of calories is the best way to lose weight and stay in shape. Our maintenance calorie calculator provides an approximate daily caloric intake chart that you can follow to know what calorie intake is best for your BMI. Here’s how to maximise our calorie calculator for weight loss/gain goals:

icon

Check Your Daily Calorie Intake Requirement
Jump Tag Icon

Daily calorie intake indicates the exact number of calories you need to eat or consume daily to achieve your weight goals or maintain your existing weight. Your age, gender, height, weight, and daily level of physical activity determine how many calories you need to consume daily. Our calorie calculator alleviates the hassle of these manual calculations and delivers results within seconds.

icon

Track Your Calorie Consumption For The Next Week
Jump Tag Icon

The next stage is to track your calorie consumption for 8–10 days to determine how many calories you consume each day once you receive your daily calorie requirement amount. For this, there's no shortage of health and meal-tracking applications.

icon

Cut Down or Go For a Surplus Depending On Your Weight Management Goals
Jump Tag Icon

Create a strategy to gradually reduce or boost your calorie consumption rather than suddenly. Steer clear of processed, fried, high-carb, and sugary foods if you plan on losing weight, as these foods have a lot of calories. Do the opposite if you intend to gain weight, but always avoid sugary foods as they do no good to your health in any way possible. 

icon

Follow a Balanced, Healthy Diet Plan
Jump Tag Icon

After removing all high-calorie items from the previous one, create a new diet chart with healthy foods like fruits, vegetables, fish, lean meat, salads, etc. Ensure your diet is well-balanced; consume at least 300–500 fewer calories daily.

icon

Add Exercise Alongside Your Diet For The Best Results
Jump Tag Icon

Make sure you get some exercise each day in addition to following your new nutrition plan. Progressively advance to more strenuous activities after at least 30 minutes of walking.

Benefits and Risks of Using a Calorie Calculator
