What BMI doesn’t tell you about your health

Comments 38

  1. I don't understand… BMI isn't supposed to be used the way this video is portraying it… it's almost like you set up a false premise and then argue against that premise… being overweight is unhealthy. Smoking is unhealthy, but you don't see people saying "my blood pressure is fine, so smoking isn't a problem!". Something can be unhealthy and you can currently still have good health, but in the long term you're harming your body and that's unhealthy.

  2. Really, these shortcuts to health measurement can get really contradictory when used to measure anyone outside of average. Not only will someone highly muscular and healthy be labeled as "obese" because of a high BMI, someone with very low muscle mass (like me) can get labeled "underweight" with an 18.0 BMI but have a 35% fat ratio, which is considered obese! So which is it?!

  3. No, BMI isn't the only way to understand the human body. And yes, it's useful around 80% of the time. It has limitations, but it is a useful tool! So I don't get what this video is about 🤔

  4. The problem with this is that it body builders and athletes are already aware of this and going around saying that BMI is a poor measurement of if someone is obese or not erodes confidence in the system and can stop obese people from seeking the life changes they need to be healthy.

  5. Here's the issue. Most people who are obese are bulky muscle men. They're fat. That's what everyone is overlooking. Sure, BMI isn't perfect, but it's a pretty damn good indicator of someone's health.

  6. My school told us that the BMI scale was from 0-100 and that like 80 is obese and that 5 is under weight. I’m 5’4 and 110 pounds and they told me my BMI was 34 or 36 I can’t remember

  7. Nobody ever said, that the BMI is the answer to everything. It is a simple, broadly applyable Index-number. Ofcourse it does not count in the variables of Athlets, especially those who need physical power (football, budybuilding etc.)

    BUT for every "normal" human being it is an easy way to determine if you are in fact an obese lazy ass who needs to loose weight. Because, unless you ARE a bodybuilder – a BMI of 30 is saying that you are risking your life every day with 100% certainty.

    You can show all the fancy medical-tech-toys the doctors have, but it doesnt change the fact that body positivity is wrong. And it cannot be compared with anorexia. There are multiple times more fat people is the western world than deadly-thin ones.

    Take the stairs, not the elevator and dont eat junk food. Everybody can do that and everybody can lower his weight. Atleast to be officially "overweight" instead of morbidly obese…

  8. Everyone knows this already. People that lift weights know they have more muscle mass and not to take BMI too seriously. It's still useful because most people aren't athletes and body builders. And so it correlates well with actual body fat %. Sure it will be wrong in a few cases, but it will be right 90% of the time.

    Everyone has a scale and a tape measure. No one has a MRI machine they can just hop into.
