What Is Obesity?

The term “higher weight” means excess body fat.

Doctors can measure it using BMI.

BMI stands for “body mass index.”

A BMI of 25–29.9 is classified as higher weight, while a BMI of 30 or higher is classified as obesity. (WHO BMI Classification) (NICHD BMI Information)

But this condition is not only about numbers.

Obesity is associated with health risks.

Understanding the causes and treatment of obesity can help prevent these health risks.

Obesity Classification Table

People who are heavier have a higher risk of developing obesity, type 2 diabetes, high blood pressure, heart disease, and other health conditions. Recognizing higher weight early may help prevent future health problems.

My Personal Experience With This Obesity

A few years ago, one of my friends gained weight.

• He worked long hours.
• He eats fast food every day.
• He did not exercise daily.

At first, he ignored the work.

He began to feel exhausted after that.

He had some breathing problems.

The doctor said he was higher weight and at risk of obesity-related health problems.

• He changes his habits.
• He keeps walking every day.
• He reduces junk food.

Within 6 months, he loses his weight.

His health has been improved.

This shows how understanding the causes of obesity can change lives.
