If you are asking yourself this question then you know the importance of calorie intake relating to weight loss, weight gain and your health in general.

However, there is no defining number of calories per day that we should all follow, the amount you should eat will depend on your gender, age, height, weight, amount of exercise you do and your goal (weight loss, weight gain, balanced diet).

## Calculating How Many Calories I Should Eat A Day To Lose Weight?

Calculating your needed calorie intake is actually very easy, it will only take a few minutes of your time and it will have a very good impact on your health if you use the calculations wisely. Unfortunately, this is where many people stop, because they think It is hard. Well it isn’t!

## Step 1. We Need To Calculate Your Basal Metabolic Rate(BMR)

The Basal Metabolic Rate is the rate at which your body burns calories during rest, for example when you are sitting, sleeping etc. To calculate this all you need to do is some simple maths and you only need to know your age, weight and height.

### Here is how it should be calculated for women:

U.S

Women: BMR = 655 + (4.7 x your height in inches)+ (4.35 x your weight in lbs) – (4.7 x your age in years)

Metric

Women: BMR = 655 + (1.8 x your height in cm) + (9.6 x your weight in kgs) – (4.7 x your age in years)

### Here is how it should be calculated for men:

For U.S

BMR = 66 ++ (12.7 x your height in inches) + (6.23 x your weight in pounds) – (6.8 x your age in years)

For Metric

BMR = 66 + (5 x your height in cm) + (13.7 x your weight in kgs) – (6.8 x your age in years)

## Step 2. Calculate Your Active Metabolic Rate (AMR)

The Active metabolic rate is the amount of calories your body burns during activity, obviously this is going to depend on the amount of exercise you do. Here is how you calculate it using the BMR.

For both men & women:

No or very little exercise:

- AMR will equal BMR x 1.2

Light exercise:

- AMR will equal BMR x 1.375

Moderate exercise:

- AMR will equal BMR x 1.55

Difficult exercise:

- AMR will equal BMR x 1.725

Extremely difficult exercise:

- AMR will equal BMR x 1.9

## Once You Have The Numbers..

After calculating how many calories I should eat a day to lose weight my next step would be to adjust my diet accordingly. Find out the calorie count of the foods you eat and then make yourself a diet plan.

If you need some guidance then I have written some good articles on dieting and exercise here:

However, my articles only touch upon the surface of weight loss information. For people who are more serious about losing weight and keeping it off, then I recommend this program here. I have used it and written a detailed review of my thoughts about it. It is not free, but you can get it at a discount of you follow the link through my review page.

Although something like this can seem somewhat daunting at the start, it is in fact something which will become part of your routine. It may be hard in the beginning, but with time it will become second nature.

Then it will be easier and easier to do, best of all you will reach your weight loss/weight gain/health goals.
