Body mass index is a highly utilized and well documented method for assessing risk of death from many causes, including cardiovascular disease. If you are unfamiliar with BMI, check out my video explaining it.
BMI Explained: https://www.youtube.com/watch?v=LeG45M4XTjA
Body mass index is calculated by dividing your height by your weight squared (in the metric system, in the SI system it’s a little more complicated). This gives you a rough estimate of your body habitus, and a healthy BMI is anywhere between 20 and 25. Anything over 25 and you have increased risk of heart attack among other things.
One of the criticisms of BMI, which is well documented, is that it does not accurately differentiate body fat from body muscle. For example, if you took a 6’2”, 230 lb pro athlete and and 6’2” 230 sedentary individual who doesn’t exercise, they have the same body mass index of 29.5. However, in this thought exercise, the pro athlete will have much more muscle mass and less body fat.
In other words, should people with more muscle mass and less body fat be healthier despite the same body mass index? The authors of this study wanted to shed some light on that question.
Body mass index, also known as BMI, is an objective way to describe someone’s height and weight. Overweight and obese BMI are associated with a ton of diseases such as diabetes, heart disease and strokes.
Research has shown that in individuals with a BMI over 25 (classified as overweight) and a BMI over 30 (classified as obese) the risks for the following conditions also increases:
Death from any cause (all cause mortality)
Coronary heart disease (heart attack)
Type 2 diabetes
Cancers (endometrial, breast, and colon)
Hypertension (high blood pressure)
Dyslipidemia (high cholesterol, triglycerides)
Stroke (cerebrovascular accident)
Liver and Gallbladder disease
Sleep apnea and respiratory problems
Osteoarthritis (a degeneration of cartilage and its underlying bone within a joint)
Gynecological problems (abnormal menses, infertility)
Metabolic syndrome
