While being obese might not look that different from being overweight, especially if you're just barely obese, it can come with a number of health risks if not addressed.

Being obese can put someone at increased risk of cardiovascular problems such has high blood pressure, heart attack, or stroke.

Being obese also makes it more likely for someone to develop type 2 diabetes. Excess weight, particularly abdominal fat, can contribute to insulin resistance and therefore diabetes.

Some sometimes overlooked problems with being obese are that it places more stress on your joints, particularly the knees, hips, and ankles. It can also affect respiratory health, putting pressure on the diaphragm and chest, making it more difficult to breathe. This can be a problem when working out or if you get a respiratory illness. Being obese can also contribute to sleep apnea.

If you’re concerned about being obese, it’s important to talk to your primary care physician or another medical professional. They can help determine the underlying causes, assess your nutritional needs, and develop a plan to achieve a healthy weight in a sustainable manner.

Important notes about BMI

While BMI is useful for categorizing someone's weight status, it isn't able to take into account someone's unique body composition, muscle mass, or overall metabolic health. For example, athletes and bodybuilders with high muscle mass may be classified as overweight or even obese based on their BMI despite being in great shape and having a low body fat percentage. Similarly, people with osteoporosis could have lower BMIs due to decreased bone density.

These are extreme examples, but they do illustrate the limitations of using BMI only to evaluate your body weight. That's why alternative measures such as waist-to-hip ratio, waist-to-height ratio, and body fat percentage can often provide a more accurate assessment of someone's health.

Of course, there are benefits to BMI: it's a quick, easy, and free way to get a rough idea of what kind of shape you're in, and you can track it over time to identify changes. And if you're not a bodybuilder or don't have health issue that could skew your BMI, it's a pretty good indicator of your weight status.

What's the formula for calculating BMI?

The formula for calculating BMI is weight (lb) / [height (in)]² x 703. In the case of someone who is 5'5" and 347 lbs, the formula would be [347 / 65²] x 703, with a result of 57.7.
