What is Body Mass Index and How Should I Use It?

What is Body Mass Index?

Body Mass Index (BMI) is an indicator of the amount of body fat for the average person. It’s used as a tool to identify if an adult is at a healthy weight and healthy body fat level.

Before we dive into BMI, let’s first review the benefits of maintaining a healthy weight: 

  • More Energy 
  • Less Joint Pain 
  • Better Sleep  
  • Better regulation of blood pressure (better heart health) 
  • Decreased Risk of Diabetes 
  • Longevity 

These are just a few of the benefits of maintaining a healthy weight, but what does BMI have to do with your weight and what does it mean?

For years, BMI has been used by healthcare providers as a measurement to define if a person has too much body fat, and if so, whether it “presents a risk to health.1 

How to Calculate Your BMI

Since we know maintaining a healthy weight is beneficial for your health, let’s take a look at how to calculate body fat by just using your weight and height.

Calculation: Divide a person’s weight in pounds, by their height in inches. Divide the answer by height in inches. Multiply the answer by 703 (703 is the conversion factor to change units from metrics (meters and kilograms) to imperial (inches and pounds).  

Example: Weight is 140lbs and Height is 5’7” or 67in 

140lbs / 67in = 2.089  

2.089 / 67in = .0311 

.0311 x 703 = 21.9 

BMI = 21.9 

Accuracy

BMI is not a perfect measure and everyone’s body composition is different. BMI is a simple tool of weight-for-height and everyone’s height and weight varies. Therefore, this means BMI is not directly measuring body fat.  

Muscle and bone are denser than fat, which means BMI is not accurately addressing body fat. If an athlete or a muscular person calculated their BMI, their BMI might be high because they have more muscle.

According to BMI calculations they would be considered overweight, however, they don’t have too much fat on their body. Since most people are not athletes, BMI might be a good gauge for body fat.  

Healthy BMI Range 

So, what does this mean for you? The World Health Organization states that a healthy BMI range for adults is between 18 and 24.9. Overweight range for BMI is between 25 and 29.9, and obesity range for BMI is 30 or higher.1 These BMI ranges in adults are the same for men and women, regardless of their age.

How to Add Exercise to Your Busy Lifestyle

How to Add Exercise to Your Busy Lifestyle

Making time to exercise can be a balancing act… work, kids, after school activities, family & friend obligations, just to name a few.

The most common excuse for not exercising: “No time,” says clinical psychologist Lavinia Rodriguez.1

How to make time for exercise

How do you make the time for exercise when you have no time?

Morning Workout. Fitness experts will suggest a morning workout. Why? Because life gets crazier as the day goes on. By getting in a workout first thing in the morning, you have time for other day-to-day stuff without having to think about when you are going to fit in a workout.

Find a Friend. Grab, drag, or bribe a friend to come with you. Having your best bud or accountability partner come with you can make workouts so much fun! Keep one another accountable, set goals, or create challenges with one another. Having someone to go with you means you are less likely to make excuses not to go to the gym.

Write it down. Create a schedule for yourself. Take time on Sunday evening before you go to bed and write down your schedule for the week. Then find pockets of time where you can go to the gym and commit to your schedule. Once you’ve committed to your schedule, it’s less likely that you are going to break it and less likely to make excuses.

Set small goals. Small goals can be BIG wins! Start with working out one or two days per week. These small goals will turn into a routine and eventually become a habit.

Decide. You must decide that you are going to make time for exercise. Make the decision and follow through with it. There will be days when you don’t want to go to the gym, that’s when you need to prove your willpower.

Set your alarm. Set your alarm so you don’t forget. If you set your alarm for the morning, it’s not always easy waking up early. Challenge yourself not to hit snooze. Put your feet on the ground, get vertical, and start walking around. If you set your alarm for the afternoon, you may be hurting for time, but everyone needs to take a break. What you will soon realize is that working out helps improve productivity. So, hit the gym!

Don’t stress. Bottom line, any exercise is better than no exercise. Do what you can, when you can. Don’t stress out or put pressure on yourself because you didn’t make it to the gym.
