Per their official weigh-ins prior to the fight:
Mayweather's BMI at 5'8", 149 lbs. comes in at 22.7
McGregor's BMI at 5'9", 153 lbs. comes in at 22.6.
The "normal" range for BMI is 18.5 to 24.9. Both Mayweather and McGregor fall comfortably within the "normal" range.
Not sure what your point was.17 -
Not sure but what's suitable BMI for 5.4 female?0

BMI is a weight range - Body Mass Index. You can find BMI charts that will show the range you should be in quite easily via Google. Where you ultimately want to end up within that range is up to you.3 -
Thank you so much. Let me check mine first.0

Good discussion, yes BMI is a scale defining the required weight for a person as per his height, age and current weight.

I can not for the life of me work out how an IBW which is an exact number for every person of the same gender is anything but a total joke personally. That a person with a small frame should weigh the same as a person with a large frame. That someone of Asian decent should weigh the same as someone of African decent. I used two different online calculators for IBW and they gave different numbers. Which one is the ideal one? Also trying to work out why comparing Mayweather to McGregor proves any kind of point.
Using the BMI scale isn't going to work for everyone, especially those with a muscled athletic build, but for most their healthy weight range will fit within this scale. It is a range for a reason. Because everyone has a different body build meaning not everyone will be healthiest at the same weight.8 -

Point was that BMI allowes both to carry 20lb more belly fat and be normal . It's too loose. So for folks who are trying to be fit, don't just get to the edge of it, you want to be at center, and especially for women, then the center is still high.
With IBW, you can't loose 20lb more.

I think with BMI people get all caught up on a "perfect #". Then they hear others say it's "rubbish". And honestly, people's perception of the correct body proportions are all messed up. We've gotten used to most people being overweight. Then people feel like it's too much work to get within that window, especially if you've alway been on the heavy side (fat, not muscle). And because it's easy to listen to others than actually lose more weight, they stop, because it's easier. Not everyone will fit in that healthy weight window, but it's a good gage for most of the population. You just have to know yourself and how you are built.
I know, for myself, I feel my best at a 21 BMI. According to the window, I'm healthy up to 179lbs. But even at 165 I start feeling "tubby". The perfect weight for me is 150, at 5'11, and a 38 year old woman. I just have a hard time staying there...hence why I'm here, writing this. I need to keep coming back to MFP after 6 years on and off to get a little 'reality check'. Basically proving that once you hit goal, it's not over.3 -
Why, if they were carrying 20 lbs more would it be "belly fat"? Not bone density, additional muscle mass and general body fat? To state that this additional 20 lbs would be all belly fat is absurd really.rfrenkel77 wrote: »

You can "absurd" all you want, reality is that those 2 fit males, athletic, were at ideal weight for their performance. No one is carrying 20lb of more bone mass at a given height, or you better check for tumor. And we are not talking about bodybuilder who alters his hormones so he gains 20lb more muscles. If you have extra 20 on you, it's fat. We all pacify ourselves that it's bone mass, it's muscle, it water bloat, we are all so loving and full of excuses for ourselves. It's ok to be more critical, and push ourself into fitness. Get inspired and improve yourself.12

I'm 5'8". The median for my BMI range is 143.5. The IBW for my height is 138-141.
So you're telling me that, especially for women, the center [of the BMI range] is still high? It's a two pound difference...not a 20 pound difference. You're splitting hairs over a negligible figure.
IBW still fails to account for people who are skinny fat (as does BMI). Both have their faults.4 -

For a particular sporting event/performance.
Additionally, if you were a fight fan, you would know that their "official" weight bears only passing relationship to their fighting weight.

Mayweather is a little light there and McGregor looks very big at the weight. He will be 15-17 pounds heavier tomorrow night and will try and bully Mayweather physically early. Great weigh in great atmosphere
Great weigh in for Conor Mac2 -

Wrong. My husband is 5'8" and 175#. That's an overweight BMI and, according to IBW (lol), his ideal weight is 148-153.
His body fat is 12%. No hormones, no steroids.
Maybe now you can get inspired and improve yourself...let go of the excuses that say it's impossible to have a few extra pounds of muscle with a disciplined diet and workout routine. It's okay to push yourself into fitness.

Stanman, a 153lb body would look like a marshmallow with additional 17 lb of water. It's was a boast mcgregor made, its nonsense.
Example. I'm 155, i have abs, was very sore for few days after overtraining, so sore I could not attend gym, my body was recovering for 3 days, and I was weighing in at 161. This 6lb water retention is heavy in the abdomen and chest. It was very notable and I could not see abs. I was fully recovered by day 3, thanks for caring, and body flushed out. So that claim was BS, it was extra obvious to me, since this was real recent.6 -

Clearly you don't understand the fight game... 17 lbs of water(10% of TBW) is typical.4 -
The BMI chart is a range for a reason. Especially for women.
I'm 5'1", 122lbs, BMI of around 23 which is on the higher end of 'normal'.
I have a decent amount of muscle mass, I'm a pear shape, and have E cups. My BF% is at most 28-30%.
Both Devine & Hamwi put my 'ideal weight' at 105lbs. That would make my BMI a totally reasonable 20 (I know women my height that probably weight that much and look good doing it.)
But if I personally were to lose that 17lbs (of fat) I'd be about 14-16%BF, which might be the Olympic 'ideal' but it certainly isn't manageable for a non-competitive athlete. I'm never going to that IBW unless I lose a some muscle mass, or get a breast reduction. Which is why there is a healthy 'range' with the BMI.
Certainly people should push themselves and try to be their best and get fit. But also a single IDW for everyone the same height is ridiculous.7 -

BMI loosely defines a healthy RANGE where most people will probably not have an elevated health risk because of their weight.
You cannot define athletisism or performance by weight as it involves too many other variables.
And your fighters do not have the same body type as a powerlifter or a long distance race walker or a swimmer who are all athletes.
In your zeal to poo-poo lack of perfection you've gone off on a tangent my friend.
Getting one's weight in the normal (to slightly overweight) range is a health issue.
Esthetics and performance are neither purported to be measured by BMI nor narrowly enough defined by weight to find a meaningful answer there.
M 5ft 8" 150lbs. You still know nothing about the person's physique, other than that probably their weight does not pause a health issue.12 -
It's important to understand that BMI was developed to measure populations of people, not individuals. Due to different body builds, BMI is a poor indicator of healthy weight for individuals, because it may understate or overstate your healthy weight based on your frame. Body fat percentage is a better gauge of where you are and where you should try to go. Most of us, when losing weight, really are just trying to achieve an ideal body, which is really just lower body fat. You can find online good resources for ideal body fat ranges for different genders and ages. Don't use the hand held or scale body fat measurement tools, those are rubbish and don't work. Having someone with calipers or another more scientific method will get you closer to a better measurement.6

The bottom one, I can assure you, I look too thin (and this is from someone who has historically had a very warped body perception in terms of thinking I needed to lose weight when I didn't), the top one, actually about right for me, though 900g lower than my current goal weight (which is hiding under my winter insulation). We'll see how I'm feeling (or rather, looking) after a few months of recomp, and I may or may not drop a little lower. Either end of BMI is just LOL.
Results:
Based on the Broca formula, your ideal weight is 57.8 kg.
Based on the Devine formula, your ideal weight is 59.63 kg.
Based on the Robinson formula, your ideal weight is 59.44 kg.
Based on the Miller formula, your ideal weight is 61.45 kg.
Based on the Hamwi formula, your ideal weight is 59.29 kg.
Based on the Lemmens formula, your ideal weight is 62.09 kg.
Based on the BMI range formula, your ideal weight is between 52.21 kg and 70.56 kg.
When I look at a person, I ask, can he she lose 20lb? 95% of women and men...absolutely.! I live in US, folks are obese here. Of course, according to BMI, they are perfect.
<<<5'10" 182 Lbs...not obese and not over fat...The IBW calculator say 160...I'd be skin and bone at 160.5
