# Daily Calorie Calculator - Calculatorall.com

The daily calorie calculator is used for estimating the amount of calories you should consume every day. This calculator also gives you a few simple guidelines on how you can gain or lose weight. Also, if you prefer using SI units then use "Metric Unit" option.

The calculator here uses Mifflin-St Jeor Equation that calculates BMR, and the results produced by the calculator are basically the average estimates. BMR or basal metabolic rate is actually the energy that you expend everyday at rest. Though there are a few other equations available as well for performing such calculations, but Mifflin-St Jeor equation turns out to be most accurate of them all for the calculation of BMR. Let's take a look at this equation:

For men: BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) + 5

For women: BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) - 161

The resultant value is the estimation of calories that one should consume on any given day for maintaining the body-weight with the assumption that they're at rest. The equation is multiplied with the activity factor, which is usually 1.2 - 1.95, depending on the typical exercise levels of the person. The result of this multiplication is actually more realistic number to maintain the body-weight. 1 pound body weight is equal to almost 3500 calories. And for losing 1 pound weekly, one should be cutting down on 500 calories a day.
Even though this daily calorie calculator can give you the values for how much calories you should consume daily for maintaining, gaining or losing weight, regular exercise and proper diet would be your best shot at losing weight. It's not recommended to lose your caloric intake beyond 1000 calories a day as it can be quite unhealthy to lose 2 pounds a week and may lead to opposite effects in future as it will reduce your body's metabolism.

How It Works?

This daily calorie calculator requires you to enter your age, height and weight. Besides, you have to select your gender and the activity level as well. You can also choose between US and Metric units, whichever you want to use for calculating the results.
The result shows you the number of calories you need every day for maintaining your current weight, the number of calories you need every day for losing 0.5 kg or 1 kg weight in a week, and the number of calories you need to every day for gaining 0.5 kg or 1 kg weight in a week.
Besides this daily calorie calculator, you also get a Food Energy converter that shows you exactly how much energy you get by consuming a certain number of calories. It can work the other way around as well by telling you the number of calories you need to consume for getting a given amount of energy.
So, use this calculator to find out estimated number of calories that you need to consume every day while keeping in mind whether you want to maintain, lose or gain weight.
