BMI Chart and Categories:

The BMI tool is simple to understand, yet it is one of the most competent gizmos during your fitness journey. As the name implies, it helps you figure out whether you are obese or healthy. Where children and teens are concerned; BMI is compared through percentiles instead of fixed numbers varying with sex and age. 

Visual BMI Chart

• Underweight: Below 18.5
• Healthy weight: 18.5 – 24.9
• Overweight: 25 – 29.9
• Obese: 30 and above

Child & Teen BMI Percentiles (CDC ranges)

• Underweight: Below 5th percentile
• Healthy weight: 5th – 85th percentile
• Overweight: 85th – 95th percentile
• Obese: Above 95th percentile

Always remember that BMI is merely a screening tool not a medical diagnosis. It is always important to visit your doctor for the best treatment. Besides this, it must be noted that BMI ranges are fixed for adults but vary for teens and children depending upon two main factors: 

• Sex/gender
• Age

BMI Formula Explained

Metric Formula:

BMI = weight (kg) / [height (m)]²

Steps to follow:

• Weight in kg
• Height in meters
• Square your height 
• Divide your weight by your squared height.

Example:

Weight = 70 kg, Height = 1.75 m

BMI = 70 ÷ (1.75 × 1.75) = 22.9

Imperial Formula:

BMI = weight in pounds / (height in inches)² x 703. 

Steps to follow:

• Weight in pounds.
• Height in inches 
• Take a square of your height.
• Divide weight by the square of height.
• Multiply the answer by 703.

Example:

Weight = 160 lbs

Height = 5 ft 6 in (which is 66 inches)

Multiply weight by 703

160 × 703 = 112,480

Square the height (in inches)

66 × 66 = 4,356

Divide the two values

BMI = 112480 ÷ 4,356 = 25.8

Health and BMI

BMI is widely used to estimate body fat and related health risks. Checking the BMI after a certain period of time is compulsory. Higher BMI can be alarming, leading to diseases like heart malfunction, diabetes, and high blood pressure, and low BMI can be the seed of undernutrition.

Limitations:

• If you are an athlete and have a high BMI, then it is due to muscles, not fat.
• Pregnant women and seniors require special consideration.
• It does not measure body composition directly.

Despite limits, BMI remains useful for weight loss tracking, fitness planning, and public health screening.
