# 5 Fast and Free Weight Calculators to Try Now – My Bariatric Life

Health Guide
• 1. BMI Calculator

Most everyone is familiar with the BMI Chart, which standard for Body Mass Index, used for calculating ideal weight ranges. The BMI was developed in the 19th century as a formula to give the government a quick and easy way to measure the degree of obesity of the general population.

However, BMI does not give an accurate picture of health weight. For one thing, BMI does not take into consideration waist circumferences, which is a clear indicator of obesity level. Read Belly Fat is More Dangerous Than Obesity, New Studies Show.

Another reason is BMI does not indicate level of fatness accurately. A person could have a high BMI but not be overweight or obese; rather the person can be fit with very little fat and high muscle mass.

That said, most of us are not athletes having a high muscle mass. So, chances are that if your BMI is high then you need to lose weight. Use our BMI Calculator.

For more precision, specialists recommend using a combination of Body Mass Index (BMI), Body Fat, and Lean Body Mass to figure an individual’s ideal healthy weight.

2. Waist to Hip Ratio Calculator

Central obesity is measured by comparing the circumference of a patient's stomach to a circumference of the hips. Use this Waist to Hip Ration Calculator. Women with waist-to-hip ratios of more than 0.8 are at increased health risk because of their fat distribution. Men with waist-to-hip ratios of more than 1.0 are at increased health risk because of their fat distribution. Using this calculator, my waist-to-hit ratio is .8.

3. Body Fat Calculator

Body fat calculators give an indication of body composition (muscle and fat). Two people with the same body weight and height could have completely different body compositions. This Body Fat Percentage Calculator estimates body fat using weight, age, and waist size.

You will want to be in the lean or moderate classifications for body fat percentage. I calculated my body fat and it is moderate.

Body Fat Rating Scale

 MEN WOMEN Exceptionally Lean 6-10% 10-15% ** Very Lean 11-14% 16-20% ** Lean 15-18% 21-25% Moderate 19-24% 26-29% Overfat* 25%+ 30%+

*Men are considered borderline at 25% body fat and clinically obese at 30%, while women are borderline at 30% and clinically obese at 35% body fat.
**A lower body fat percentage for women increases chance of amenorrhea (cessation of menstruation).

4. Home Body Fat Test

What Is A Healthy Amount Of Body Fat?

Depending on your race, recommended percent body fat may vary. Below is a chart of percent body fat found in different people, including the highest and lowest percents tested.

Range of Percent Body Fat in Different People
(Percent body fat found through the method of underwater immersion testing)

 Men Women Fattest Covert has tested 55% 68% Average American 22% 32% Healthy normal*: African-American 12% 19% Asian 18% 25% Caucasian 15% 22% Top Athletes 3-12% 10-18% Leanest tested 1% 6%

The bones of African-Americans tend to be dense and so they sink easily in water. On the other hand, the bones of Asians are light and porous so they tend to float. To allow for these differences, healthy African-Americans should have a lower percent body fat than Asians and Caucasians, while Asians should have a higher percent body fat than African-Americans and Caucasians.

5. Recommended Daily Calories & Fat Calculator

How Much Fat Should I Eat?

The average American gets approximately 45 percent of his/her calories just from fat. This is too high for most of us.

Here are the recommendations for my fat and calorie intake using this calculator:
