What confuses me is how people that are 300+ lbs can maintain that weight. From a math standpoint wouldn't they have to continually increase their caloric intake to maintain that level?

Yes. But, it doesn't take that much more food to get a ton of calories.

I mean the TDEE of a 300 pound sedentary person is something like 2800-3000 calories?

That's a single slice of pizza a day too much.

Well like, say this person ate 1 slice a day to much to reach 300. Wouldn't he need more slices per day just to maintain 300? So in effect it would be 1 slice to 200, 2 slices to 250, 3 slices to 300?

I used to be in the 27 range with 5% body fat. Now I'm in the 32 range with a much higher fat ratio

Damn you appetite without the corresponding workout routine!

5% is super low and takes bodybuilders and competitive athletes an immense amount of work, time and discipline to achieve. How did you determine your bodyfat? Some people use DEXA, but this also can be inaccurate based on the amount of overall hydration and glycogen in the tissue. The lowest I ever measured was 7.8% using hydrostatic underwater weighing.

If I understand what you're saying correctly, yes.

The idea is that it doesn't take much to start balooning.

Also, I call shens on 5% body fat. That level is reserved for bodybuilding competitions with extreme fasting for a single day of showing off.

5% is impossible to keep without serious health effects.

I don't foresee myself ever getting under 28 on the BMI. But then again it is a rather poor and lazy method of gauging one's health.

BMI is basically meaningless.

Waist/Height measurement is a much better way of determining physical fitness level but even then it's not showing the big picture.

Maybe slightly but not worth much more if anything at all.

What you want is body fat percentage but the ideal body fat percentage will vary by individual based off ethnicity and sex.

This. Bad calculations. If you can't see every single surface vein, you aren't near 5%. And nobody can sustain that for long.

Bodybuilders also go into dehydration to get their skin highly taut to further show their work - then pig out after a competition.

For the other 99% of the population, it's not the freakin' bible or something, but BMI (plus or minus a couple points) is a decent guideline.

No it is not.

The given value of BMI is based off Men and Women of usually Anglo ethnicity.

Many Africans and African-Americans would fail the BMI test yet would be far more fit than many white folk from Western or Southern European ancestry.

How hard would you say the loss of body fat and water from cutting is on the heart and any related hormones for someone?

Side lecture:

If you can see you actual abdominal muscle definition, you don't have much in the way of adipose fat, and you generally don't begin shedding large quantities of adipose fat until you have cut down a majority of the visceral fat that is behind the abs (gut interior, between organs). That's the fat nobody should have, it's bad, bad stuff for your overall health. Adipose fat is actually pretty good for you and useful, and if anyone were to get down to sub-5% total body fat, your health is likely taking a nose dive. Heck, I've seen mention that under 8% for a male between 20-40 is unhealthy. Women usually are advised not to cross below 10-13%, and women can see abdominal definition earlier than men due to physiological differences in where fat is stored.

Got 6 abs here... sometimes 8.

And I like some abs on women, it is sexy. Not huge abs.. but just a little. Hard to come by though.

This was while I was playing college football and running spring track at the same time. Morning football workouts, track practice in the afternoons. The football program used a water tank to determine all of our body fat% at the beginning and the end of winter workouts to determine muscle mass growth. I went from 175 pounds at 12% body fat to 189 pounds at 5%. I think over the ~ 12 week program I put on 26-27 pounds of muscle. Cant remember the exact number, been a few years

Yeah, I honestly call into question the 5% claim too. I can maintain 8% naturally with 2 HIIT workouts a week, using my FBV platform 5x a week and certain supplements, while still enjoying food. Going below this number gets mighty tough. For someone athletic, I believe the essential fat needed is around 6% and going below this number is likely foolish.

For an example of 8% body fat, Greg O'Gallager had a DEXA body fat test performed. He definitely looks to be in the 8% range to me.

However, I doubt the accuracy of the same machine that gives Jamie Alderton a reading of 13%, when to the naked eye he looks right around 9%.

Hydrostatic weighing is still the most accurate and least expensive.

This guy claims to have 1% body fat, more likely around 3% and looks really unhealthy.

It's definitely possible in a young prepubescent teen or those in their formative years. Obviously it gets harder as body metabolism and hence GH production slows with age.

Being 20 years old and working out that much it is amazing what a body can do when subjected to that kind of stress.

Wish I could get back to the low teens in body fat right now. That would make me extremely happy!

I'm 5'11" and weigh from 158-162 lbs. So, I'm 22 at 158, 22.3 at 160, and 22.6 at 162.

FWIW: I'm 48 years old, have 6 pack abs, and very visible veins in my arms / legs. I've been running for over 10 years and got into triathlons last year (so added in Biking and Swimming). It has been less than 18 months that I really got serious and lost enough weight to be 'where I should be'. I recognize that we all likely have a different idea of what weight we should be. The guys at work call me a 'stick figure'. But, they always ask me what I'm up to and what I've done lately. This year alone I've run 26.2 miles twice and rode 100 miles twice. So, yeah, I'm pretty active. I look pretty much like the %10-%12 picture, but with veins showing. I definitely sink if I don't actively tread water.

The bottom line is that I'm happy with how I look in the mirror when I'm naked. So, I'm not overly concerned with BMI numbers.

BTW, here's the point in Jamie's video where the DEXA technician gives an example of a tall and skinny male (height: 177cm/5' 9.5" weight 69kg/174lbs) with perfectly acceptable BMI of 22, while obviously being technically obese at an astounding 31% body fat. It's demonstrable proof of inadequacies in the BMI metric and the modern-day deleterious effects of ubiquitous refined carbs.

More people than ever suffer from metabolic syndrome as skinny fat people, while being totally unaware.

Nuts.

I didn't think a person could contain that much fat and still have a visibly skinny look. D:

I know I've got fat to lose, I'd be curious to see my actual body fat percentage. Definitely visceral fat that needs to be cut but it shouldn't be an extraordinary amount (I hope! D. I imagine things should check out in different ways though, because a few years ago I had blood work done checking out numerous different health factors, and my doctor said the numbers showed me being far more healthy than the average person my age (around 24 or 25 at the time). Blood pressure, metabolic panel, lipid panel, a thyroid test, possibly the sedimentation rate but can't remember. All looked great according to the doc. Bad interpretations, possibly, but I think that should at least mean I don't have a freakish amount of visceral fat (which would drag down those test results due to the crap visceral fat produces)
