Brilliant video! I am in the US and have been getting DEXA scans for 4 years and no one ever explained this to me!! After my last scan where my visceral and body fat % was the highest it's ever been and my "consultation" with my current DEXA provider got me little to no guidance, I was so frustrated that I began to research and found this video. I was able to use your online calculator and see exactly what changes I need to make to meet my goals in the time I want. This is especially important for me because I want to lose body fat to have a future healthy pregnancy and I need to do that in a certain time. I am now going to be focusing on my LBM and FBM instead of %. THANK YOU! I wish I could come to the UK for a consult. I bet it would have saved me 4 years of spinning my wheels!
Hi Jenny. We’re thrilled our video was so helpful and beyond British shores too! There are other videos on our channel and a few more are coming soon. At Bodyscan we believe we’ve done more body composition DEXA scans than anyone in Europe so we know how to interpret the numbers for every individual. Pleased, too, that you found the DEXA calculator useful. Thanks again and we wish all the very best for your future pregnancy. Best wishes!
@@Bodyscan There is NO study that suggest people with a certain percentage of fat or amount of fat are healthier. When I wrestled I had the lowest percentage of body fat. Roughly 6% via pinch test performed 2 different days. I was frequently malnourished between meals, developed heart issues, frequently had infections and join pains. I stayed lean most of my life then when I got to 20-30% body fat I no longer have joint issues, my heart issues have largely resolved, rarely get sick, have better focus and motivation. With all that data its time to do a prospectus study to determine if people who lose or gain body fat, live longer, have fewer illnesses, are more active or what not. When my friend was a professional cyclist he said never stand when you can sit, never sit when you can recline. His entire life was losing weight while being able to peddle a bike fast. His body is destroyed. Shame on you for suggesting a strong guy with 20% body fat should loose fat. As a Medical professional you should do no harm.
@@MichaelMantion There are also studies pointing out MRI's and DEXA scans can be as much as 20% off... When we're talking about tracking small changes and progress over things like 6 months (so their marketing can continue getting paid), 20% literally means it is not a clinically useful tool. DEXA scans were created to diagnose osteoporosis, and found it has some useful things, then the marketing team went off about 99% accuracy. No it is not. There are tons of bodybuilders showing before and after scans. i.e. Mike Israetel shows he gained 9.5lbs muscle and went down from 6.9% to 6.8% body fat in a short period of time. There are scientific studies showing the inaccuracies are great enough that for for actually talking about regular 6 month visits, this is a scam. Now it has a good degree of accuracy, but drink 10lb of water before the test and guess what, you have 10lb extra lean mass because it GUESSES.
Oh and keep in mind Dexa scans are pieces of garbage in comparison to an MRI. We're talking thousands vs millions, gee I wonder which one is the actual gold standard. Literally 20% off in infant studies, what a scam the way they advertise this garbage! Sorry I read studies.
DEXA gives you a more detailed breakdown of your lean body mass. If you use calipers or even hydrostatic testing, it doesn't tell you what portion of your lean mass is bone. You could be someone with abnormally high bone density or a large skeleton, and it would skew your "lean mass" significantly.
A limitation for sure, but you do get a BMD reading with DEXA to understand if you're an outlier, and absent significant BMD changes from scan to scan you can assume the majority of lean mass changes is muscle mass so quite useful
@@janet2905 it gave me that and more. It was like having GPS to your goals. Really lovely staff and procedure. I learned my bone density, body fat, muscle mass and more.
@@janet2905 We hope to see you soon. The word people use most often is 'eye-opening'. If it helps, here are our live Google reviews: bodyscanuk.com/google-reviews/
So, um, obvious question. I can get those two numbers by separating my mass into lean vs. fat mass and then just running a BMI calculation for each, but using the individual numbers?
Hi. Yes, that’s right. But the key consideration is that you have to be able to measure your fat mass and lean mass to start with, and DEXA is the best way to do that. Once you know your FMI and LMI you then have to know what is a good target for each. Please note that LMI is lean soft tissue only, it does not include bone mass (ie, it is not fat-free mass). Thanks for watching!
But if you have the body fat percentage, and the total weight and height of the person, you can calculate the lean mass... right? So does the DEXA scan just measure your body fat percentage and then do the calculation? It would be like (1-BF%)*Weight = LeanMass, right? One doesn't really need a DEXA machine for that though, surely!
Hey Neldoreth. You say "if you have the body fat percentage". How do you think BF% is calculated? BF% is arrived at from measuring fat mass, lean mass and bone mass, adding them together to get total mass. Then you divide fat mass by total mass to get BF%. You can't just get or measure body fat percentage without measuring fat mass first. DEXA not only accurately measures fat mass, but soft tissue lean mass and bone mass too.
@@Bodyscan I'm specifically responding to the section of the video labelled "Limitations of body fat percentage". Original video claims that BF% is not useful because it's just a single number. I agree with you, it can't be a single number, because it comes along with lean mass as well. Original video says "DEXA gives you two numbers", but in actuality, if you have BF%, you also have lean-mass percent. I think you and I agree, whereas the original video seems to not really understand BF%.😀
Hi again. Thanks for clarifying your point. Well, BF% is a single number, and lean mass % (LM%) is also a single number, but they are completely dependent on one another. If BF% is 24%, then LM% must be 76%. They are numerically linked - knowing one means you know the other. But physiologically, in real life, your fat mass and fat free mass are independent of each other. You can have high fat and high muscle, or high fat and low muscle, etc. What the video is saying is that you may have a high BF% but it doesn't mean you have high fat. The advantage of FMI and LMI (fat and lean for height) is that they are completely independent of each other, just like fat mass and lean mass actually are. If you know BF%, you know LM%, but you don't actually know how much lean mass that is. If you know FMI, you have no idea what LMI is. (In all the above, it would actually be more accurate to replace LM% with FFM (fat-free mass percentage.)
@@BodyscanHi l feel as though l am losing muscle mass, is this appropriate to check that and bone density? Can this tell you if there are any problems in those area?
@@janet2905 Hi. A DEXA scan will measure your lean body mass (which, to all intents and purposes, we read as muscle, though it is actually all fat-free soft tissue - muscle, organs, connective tissue, ligaments, skin, etc). So, yes, we can tell you if you have high or low muscle mass, but we won't know if it's decreasing because we will only have one measurement. We won't have any other measurements to compare it too. To detect a trend, you need a series of measurements over a long period of time. As for bone density, watch our video on that here: th-cam.com/video/uJ2DMIYa0pI/w-d-xo.html. We would not advise you to measure or track your bone density with a BODY scan because the result is not precise enough. To measure and track your bone density you will need a DEXA BONE scan (not a BODY scan).
Wasted $100 on a dexascan. Machine said i was 31% bf. Lmaooo. Thats obese. Im 5’9. 175 lbs. wear a small in workout shirts and a small in shorts. Pants size is 31/32.
It literally has an error of 1percent. I'm sorry to tell you, but youre fat. I'm fat as well. I'm 183cm tall 90kg with 34 percent bodyfat. You wearing small stuff doesnt mean your bodyfat is low, it just means your lean body mass is low and your fat percentage is high.
Hi there. In short, no. The scan measures body composition (fat and lean body mass/muscle). The two results on the report that have medical significance are for bone mineral density (BMD) and visceral fat. The BMD result is not diagnosable, only an indication. High visceral fat does have health implications - it puts you at increased risk of type-2 diabetes, heart disease, colon cancer and other diseases. But a DEXA body scan is not a general health check, it is specific for body composition. Thank you for watching.
Hmmm, not exactly. The thinner guy is just skinny (low lean AND low fat), he doesn't carry much fat at all. We do have clients who fit that description more closely, with low lean AND high fat. Someone like this would have an even higher BF% because the proportion (percentage) of him that is fat is bigger. Thanks for watching!
Just to be a dick. Kilograms measuce mass, not weight. The SI unit for weight (which is the force due to gravity) is newtons. The English system ifor mass is Slug. The english system for weight is pounds. So we always see on a box of cereal (net weight 1, poound, .4 kg. That's wrong!
