Another way to keep an eye on your progress is to find out your body mass index (BMI). You calculate your BMI by looking at your height-to-weight ratio. Your BMI won’t tell you your fat to lean mass ratio or how much body fat you have, but it will tell you if you’re overweight or obese and how far into those unhealthy ranges you are.
To calculate your BMI, do the following:
- Weigh yourself and measure your
- Use an online BMI calculator (which you can find using a search engine) or you can calculate manually your
To manually calculate your BMI, stick to these steps:
- Convert your weight from pounds to kilograms by dividing your weight in pounds by 2 kilograms.
For example, 150 pounds divided by 2.2 equals 68 kilograms
- Convert your height from inches to meters by dividing your height in inches by 37.
For example, 70 inches divided by 39.37 equals 1.78 meters
- Calculate your BMI
Your weight (in kilograms) divided by your height (in meters) × your height (in meters) = BMI. For example, 68 kilograms divided by (1.78 meters × 1.78 meters) = 21.46.
A criticism of BMI is that, because it can’t show body composition, if you have a lot of muscle of on your body (which weighs more than fat), you may get skewed results. However, as with the body composition or regular body weight scales, tracking your BMI may work for you simply because it’s a simple, inexpensive way to see the trending of your weight loss as you begin incorporating fasting into your life and throughout your weigh loss journey.
