How many obesity classes are there and what do they mean?

I've been hearing about different classes of obesity and I'm curious how many there are and what the specifics are for each class. Can someone help explain?

There are actually 3 classes of obesity, each with increasing health risks. Class 1 obesity is a BMI of 30-34.9, Class 2 is 35-39.9, and Class 3, also known as severe obesity, is a BMI of 40 or higher. These classes help healthcare providers determine the best course of treatment.

It's important to note that even a small increase in weight can lead to health issues, so it's not just about reaching a certain class of obesity. Prevention and early intervention are key in managing obesity and its related health risks.

Lifestyle changes such as regular physical activity, a balanced diet, and stress management can have a big impact on weight management and overall health. It's also important to address any underlying factors, such as mental health or sleep issues, that may contribute to weight gain.
