How much should i weigh

Your optimal weight depends on your height.

You can use BMI - Body Mass Index to calculate your optimal weight.Healthy BMI range is 18.5 - 25.

Here is how you can calculate your optimal weight range.

Step 1:

Measure your height in meters.(Or measure your height in inches and convert it to meters by multiplying that by 0.0254)

Ex:If your height is 60 inches, your height is 60 x 0.0254 = 1.524m.

Step 2:

Now calculate the square of your height by multiplying your height by itself.

Ex:If your height is 1.524m, square of your height is 1.524 x 1.524 = 2.322576

Step 3:

Now we are almost done!

To calculate the minimum weight you should be at (in kilograms), multiply the number you obtained by 18.5


Ex:If you got 2.322576 as the square of your height, your minimum weight should be 2.322576 x 18.5 = 42.967656kg (let's round that up to 43 kg)

To calculate the maximum weight (in kilograms), multiply the number you obtained by 25.

Ex:If you got 2.322576 as the square of your height, your maximum weight is 2.322576 x 25 = 58.0644kg.

i.e If your height is 60 inches, your optimal weight range is 43 - 58 kilograms.

To convert kilograms to pounds, multiply it by 2.20462

Ex:58kg = 58 x 2.20462 = 127.86796 pounds.

How to gain weight

If you have to reduce your calorie intake to lose weight, it's obvious that you have to increase your calorie intake to gain weight.

If you need 2000 calories per day to maintain your current weight and if you eat 2500 calories per day, you have 500 extra calories.

These excess 500 calories of energy will be stored in fat stores for future use and as a result you gain weight.

If you continue to eat 2500 calories per day for a week, you have 500 x 7=3500 extra calories which were stored as fat in your fat stores.

Since 3500 calories is the rough estimate for the energy contained in one pound of fat, now you have gained one pound of weight.

What is a healthy rate to lose or gain weight

A healthy rate to gain or lose weight is 1 lbs to 2 lbs a week(less than 2 lbs per week).

So if you need 3000 calories per day to maintain your current weight and you want to lose weight at a rate of 1 pound a week,you have to eat 2500 calories per day.

If you want to lose weight at a rate of 2 pounds a week,you have to eat 2000 calories per day.
