How Should You Measure BODY FAT? 

300k would be just matter of time.... you are going to explode Mark I see at least 2M subscribers in coming 2 years .... There is no one better than you in world of fitness youtubing. Wish you all the best and thank you for all the knowledge and motivation.

Not bad for a bet with your son 😂

@@GovernmentName95 yep. I think I won 😂

True

and for full audio analysis take your 4 year old child in there with you. An ironic lack of sugar coating.

absolutely!!! haha.... but after losing over 50lbs in the last year I now intentionally pop in and try clothes on in those places, to make sure I still look great, haha.

😂😂😂 According to those things I consist of at least 90% fat. Even though I'm actually small.

Forget all this Peloton nonsense, where's the exercise bike that turns a generator that powers your RU-vid fix?

Doug Lisle? Love him, he’s hilarious!

@@ragel1486 Yes, Dr. Doug Lisle. His laugh is infectious, isn't it? :)

I can gain and lose almost 3kg in a week, worrying about weight is pointless, lean muscle mass vs fat is what most people are really concerned with. I'm wanting to get into ultrarunning, to go from obese to an ultrarunner is very impressive. I'm hoping to attempt my first 60k run this month when we get a clear day. Also got my daughters flying over to visit next month so wanting to lose this last bit of stubborn fat 😂 hoping doing some daily half marathons and an ultra will do it in time, plus some weight training.

I try 😂

Thanks Paul 🙏

Send me £100 and a photo. I’ll do it for you 😂

I'm going to be pedantic about this and point out that mirrors aren't free.

​​@@Gekkibi they are free for you if you use a public one. Depending on which one you use the charges might not be.

@@Gekkibi Especially those fairground mirrors

@johnfriedl7126 going half-naked in front of a public mirror is especially not free, depending if there are witnesses. ;)

Thats not true though. When I was anorexic I was half a pound away from being double digits on the scale (lbs not kg) as a 5'6" adult woman and I thought I was massive

I bought a “smart scale” that provides BFP along with weight and some other metrics (including the current weather conditions!). My body BFP initially was indicated as 30% which is ridiculous. I’m 5’ 10” and 170 lbs and training hard for an Ironman 70.3 and an accomplished marathoner. I don’t have a 6 pack but I’m close. So I went to a lab and paid to have my body composition measured professionally, they measured BFP of 17% (not bad for 74 years old). Reading the scale instructions I found it will allow you to enter a calibration data point so I entered 17%. Now every day when I weigh myself the scale tells me my BFP = 17% ??? I’m happy with the smart scale though because I find the weather conditions report useful information when deciding how to dress for my morning run.

Same as my dad and mam (and me!) If your pants don't fit, pull away from the table!

My wife has some “smart scales” which allegedly measure body fat percentage (and lots of other internal measurements). When I got on it said my body fat percentage was 30%. I knew this was very wrong just based on how I look and my waist size. Later on I discovered that there was a setting in your profile for “athlete” (i.e. for fit and active people). When I selected that, it suddenly started telling me the percentage was 17%. Now that seems a little low to me, but much closer to the correct figure. But you might find that there is some setting on your devices which “corrects” an obviously erroneous figure.

I’ll take that compliment 😂

I’ve done both been ripped and fat off and on TRT. Only difference it made was motivation to train was higher on TRT. Physically body fat levels no difference. In fact, way easier to put on fat on TRT as appetite is so high.

@@MarkLewisfitness thanks for your rapid reply - that's a very useful insight. Your videos are super motivating and meaningful, keep up the great work!!

Faulty mirror? 😂

Was it the Mirror Erised from Harry Potter?😜

@@isaT I wouldn't say so. My body fat was below 10% and the scale said 30%.

Season 1-4 the best 😂

Yeah If they say you are too fat then you are too fat. If they say you need to eat more then you are probably fine. Not speaking from experience or anything.

@@easternmenace Yeah over the past couple of years my friends made subtle hints,being self employed never made time for myself until last year bit the bullet and hired a personal trainer,now i am more active and receive compliments on where the other guy is🤷🏻‍♂️. I never cared about how i looked,now I’ve seen the light.

Yeh but…. We were a group of climbers and would make fun of each other that we failed a particular problem because of the amount of lard we were carrying. The fact that we were very light was irrelevant, why let a good joke go to waste with facts.

I guess

As an exercise science student at university I've had this discussion many times and from a variety of perspectives. Also used everything except hydrodensitometry and MRI myself. The most important thing with any of the body composition measurement techniques is consistency. The actual numbers are often inaccurate so it's the trend and repeatability that matters. Take bioelectrical impedence as an example. It's probably the most convenient of all. It relies on a weak electrical signal being passed through your body. The time taken for the signal to bounce back to the electrodes in the scales is interpreted using a formula that considers your height, weight and age. There are often 'modes' for regular humans and athletes. The instructions for the scale will suggest when to use one or the other. That formula is whatever the manufacturer came up with based on the electronics in their scale. Many potential variables each time you weigh in so take each number with a grain of salt. For the consistency/repeatability I mentioned above: - keep 24hr hydration consistent with previous days. Hydration significantly affects impedence and will skew the results - weighin at the same time every time. First thing in the morning before food or activity is best - go to the toilet and at least empty your bladder every time. Urine and faeces are no longer part of you and will skew the results - try to maintain the same body temp and humidity each time. That includes ambient conditions and especially the soles of your feet. Warmer skin temp or moist skin will lower impedence and can slew the result. The opposite is also true. Whatever the conditions for the first time you weigh in, do the same thing every time or if you have to change just know the numbers will be different. The above will give you a chance at producing a reliable trend over time. Some scales are better than others and generally you get what you pay for. Scales with handles are theoretically more accurate as they emit electrical signals at multiple points on the body so gather a more localised measurement. Good luck and remember that protein, a reasonable intake of carbs and fats and plenty of strength/resistance training is key to maintaining lean mass (muscle and bone).
