A result between 18.5 and 24.9 means you're in the “normal” weight range for your height. If your result is under 18.5, you're considered underweight. Between 25 and 29.9 means you're considered overweight. And if your number is 30 to 35 or more, you're considered obese.
A study has estimated very obese men aged 20 to 39, with a body mass index (BMI) of 35 or above, have a reduced life expectancy of eight years. This is as a result of their higher risk of cardiovascular disease and type 2 diabetes. For women of this age, the life expectancy is six years less.
Overweight and obesity are known to increase blood pressure. High blood pressure is the leading cause of strokes. Excess weight also increases your chances of developing other problems linked to strokes, including high cholesterol, high blood sugar, and heart disease.
An individual is considered morbidly obese if he or she is 100 pounds over his/her ideal body weight, has a BMI of 40 or more, or 35 or more and experiencing obesity-related health conditions, such as high blood pressure or diabetes.
The terms “overweight” and “obesity” refer to body weight that is greater than what is considered normal or healthy for a certain height. Overweight is generally due to extra body fat. However, overweight may also be due to extra muscle, bone, or water. People who have obesity usually have too much body fat.
So the answer to the question is essentially yes, people with obesity can still be healthy. However, what this study, and prior research, shows us is that obesity even on its own carries a certain cardiovascular risk even in metabolically healthy individuals.

Obesity affects some groups more than others
Non-Hispanic blacks (49.6%) had the highest age-adjusted prevalence of obesity, followed by Hispanics (44.8%), non-Hispanic whites (42.2%) and non-Hispanic Asians (17.4%).BMI is broken down as follows:
- Normal: 19.0–24.9.
- Overweight: 25.0–29.9.
- Obese stage 1: 30.0–34.9.
- Obese stage 2: 35.0–39.9.
- Morbidly obese stage 3: 40.0 or greater.
Obesity is a serious medical condition that can cause complications such as metabolic syndrome, high blood pressure, atherosclerosis, heart disease, diabetes, high blood cholesterol, cancers and sleep disorders. Treatment depends on the cause and severity of your condition and whether you have complications.
