How to understand FITA Body Analysis reports?

Thank you for using our service!

While the summary provides a brief overview of your results, we highly recommend checking out this blog post to gain a deeper understanding of the FIT Scanner report.

Body Type Classification

The first thing you'll notice is your body type, which is categorized based on your Body Fat Percentage (BFP), Body Mass Index (BMI), and Skeletal Muscle Mass.

Depending on the combination of these factors, your body type may fall into categories such as Underweight, Skinny Fat, Normal, Overweight, Obesity, Athlete, or Bodybuilder.

Along with your body type, you'll receive personalized recommendations for health management in the summary.

Obesity Analysis

Body Fat Percentage(BFP)

You’ve probably heard of Body Fat Percentage (BFP) before.

This represents the percentage of your body weight that is fat.

According to the American Council on Exercise, a healthy body fat percentage is typically 14-24% for men and 21-31% for women.

Exceeding these levels can increase the risk of chronic diseases, cardiovascular issues, and other health problems.

In this FITA report, this Body Fat Percentage (BFP) value is estimated using an AI deep learning model trained on paired body composition data (InBody or DXA scans) and images.

This estimation is not medical information, but rather for informational purposes only.

Body Mass Index(BMI)

Next, we have the Body Mass Index (BMI), which is calculated based on your weight and height.

It’s a widely used metric to classify individuals as underweight, normal weight, overweight, or obese.

According to the World Health Organization, a BMI of 18.5 to 24.9 is considered normal.

However, since BMI doesn’t account for body fat percentage or muscle mass, it has some limitations.

Muscle-Fat Analysis

In the Muscle-Fat Analysis section, we dive into your muscle mass and body fat mass to assess your overall health.

Weight

This is simply your total body weight and is a fundamental metric for understanding other body composition ratios.

Skeletal Muscle Mass(SMM)

This measures the amount of muscle in your body that is under voluntary control.

Higher muscle mass generally leads to a higher basal metabolic rate (BMR), which helps maintain a healthier physique.

If your muscle mass is low, incorporating strength training can help improve this.

Body Fat Mass

This represents the total weight of fat in your body, calculated by multiplying your body weight by your body fat percentage.

Like body fat percentage, high body fat mass can lead to increased health risks.

The Weight-Skeletal Muscle Mass-Body Fat Mass graph typically forms a “D-curve,”

and when the amount of skeletal muscle mass is higher relative to weight and body fat mass, it indicates a healthier body composition.

Fat-Free Mass Index(FFMI)

FFMI is a measure of your fat-free mass (i.e., muscle mass and other lean tissue) relative to your height.

This metric is especially useful for athletes and bodybuilders to assess muscle mass accurately.
(Source: Kouri EM, Pope HG, Katz DL, Oliva P. Fat-free mass index in users and nonusers of anabolic-androgenic steroids. Clin J Sport Med. 1995;5(4):223–228. DOI)

FFMI = (Fat-Free Mass in kg) / (Height in m)²

Fat-Free Mass = Total Body Weight - (Total Body Weight × Body Fat Percentage)

General FFMI Ranges:

Unlike BMI, which includes total body weight, FFMI focuses only on lean mass, making it more effective in assessing muscle mass, particularly for those with athletic or muscular physiques.

Metabolic Analysis

Basal Metabolic Rate(BMR)

This is the number of calories your body burns at rest to maintain basic functions like breathing and digestion.

The higher your muscle mass, the higher your BMR, meaning you’ll naturally burn more calories throughout the day.
(Source: Mifflin MD, St Jeor ST, Hill LA, Scott BJ, Daugherty SA, Koh YO. A new predictive equation for resting energy expenditure in healthy individuals. Am J Clin Nutr. 1990;51(2):241–247. DOI)

Recommended Calorie Intake

Based on your BMR and other body composition factors, this represents the recommended number of calories to consume for either weight loss or weight gain to achieve a healthier body.
