Are there any studies on the health of very muscular men (body builders) and there obesity?
overall a very helpful video for me, thanks to this video I’ve been able to take a few measures to limit my sugar intake, do a bit more exercise and get slightly more healthy food with better amounts of nutrients
@ovenroastedDC
they’re identical height, and weight
joe won’t be higher, he will be equal in the BMI
however he would *deserve* to be lower on an accurate health indication system, that’s your point, right?
Isnt the location of fat more important then total fat. Im not a big fan of BMI but its a starting point for my appraisals.
BMI should be used together with WC…(WC = waist circumfrence)
I don’t understand why the BMI is relied on so heavily. One flaw that I find with it is that BMI charts don’t distinguish between gender. To me it is obvious that if you weigh a male and a female, both having the same height, in general the male should weigh SIGNIFICANTLY more just because of average disparities in muscle mass and bone density. So, that would mean a woman, who is 5’5″ should weigh significantly less than a man of the same height. Can someone tell me why I am wrong?
All diets and calories are not the same. A calorie from a high-glycemic source as HFCS is much worse than a calorie from complex carbs. Watch “Sugar: The Bitter Truth”.
Of course, but i think they’re referring to weight per unit of volume…
@leglesss2012 : your comment really radiates intellect and extended education.
However, one volume unit of muscle weighs MORE than the same volume unit of fat.
lol @ your ignorance and/or trolling
Muscle DOES NOT weigh more than fat !! One pound of muscle weighs THE SAME as one pound of fat.
I’m sorry, too, I just got to your more recent post.
????If Joe and Bob weigh the SAME at the SAME height, they have the SAME BMI: Those are the only two numbers used in the calculation. But no MD worth a hoot uses BMi without also measuring the waistline, too, and muscle being more denser than fat will give Joe a smaller waist, thus lower Joe’s complete score.
@ovenroastedDC It is obvious, BMI is used just as approximation, not as exact indicator of somebodies weight status. In order to see what is somebodies weight status you have to know as you stated somebodies body fat profile, even the body frame is important, and so on…..
Add the waist to hip ratio measurements to the BMI and you will have a better indication of those with a higher BMI due to more muscle mass and a lower body fat percentage that the BMI does not account for.
excellent worker!
Hehe I knew you meant that, just messing with you.
Haha whoops, I didn’t mean to say height AND weight.
I combined my points — if the fat one and muscular one were the same weight, they would be the same BMI, which is inaccurate because the muscular one would be healthier.
(o:
No, when they have identical height and weight, their BMI must be by definiton identical as well.
It is true though that BMI and muscular people doesn’t work well.
Exactly. That was my point. Joe is healthier but has a higher BMI because of his body density. In the video there is a dip in mortality rates for people with slightly higher BMI. The studies were done using the BMI as a reference (which is understood to have limitations as a measurement of health. That was my question to the speaker. If the dip in the mortality rate for slightly higher BMI is indicative of the more fit person (more muscle less fat) or another phenomenon.
No. BMI = Body Mass Index.
The BMI system is fundamentally flawed. Take this for example: two people of identical height and weight, Bob and Joe.
Bob has 40% bodyfat while Joe has 8%. Who is going to be higher on the BMI scale? Joe is going to be higher on the BMI scale, EVEN THOUGH HE IS HEALTHIER, because muscle weighs more than fat.
The BMI system is flawed because of this.
It wasn’t explained what exactly happens when people die from these surgical procedures.
how can he really have so many malformatted slides? he obviously never heard of tabs. *tsss*
BMI = body density. People who are fit have heavier bones and more heavy muscle compared to light fat. Perhaps the mortality dip in the above normal category is because of this and not necessarily because people with a few extra pounds are healthier?
First… : )
