excessive eating

[BecomeLegendary]

Hey guys just wondering if you know of any studies about excessive eating in one sitting and where all the calories go. I'm talking about 5-10 thousand calories in one sitting. Just something I have wondered for a while. In the middle of reading all my nutrition and chemistry books and can't find anything on it. Thanks guys.

There an increase is NEAT (Non-exercise activity thermogenisis). The leaner you are, the higher NEAT is. Basically you give off more body heat from doing little things such as fidgeting over a given period of time. This could range as high as 70% of the excess calories you eat for some of the leanest people. However, if you are obese, this value is certainly lower. You'd actually need to eat this massive meal and figure what it is through analyzation.

Some of it will get stored as fat.

Your glyocogen stores will most definitely be bursting at the seams.

Yeah I figured all that. I was just wondering because it seems every two weeks or so I have a cheat day and go all out, but I am 5-6% bodyfat and it seems the cheat days don't effect me at all because I don't put on any fat at all, but I also do run a minimum of an hour each day, every other day being HIIT with 3 intense lifting sessions a week. I would think if anything it would just jumpstart my metabolism and get me burning calories again.

out of curiosity, when are you planning on eating 5k calories in one sitting?

[BecomeLegendary]

well I never plan it but every two weeks or so I will smoke to much and get munchies like crazy, thats when it happens. haha, I'm not too worried about it though, I'm already lean as **** and im a 19 yr old mesomorph.

[caa5000]

hahaha being a guy who gains weight easy I need to be careful when I do that stuff... I plan in advance with the foods :-p

Here's a bit from Pubmed that supports the above:

[caa5000]

yes so in other words

Don't pass out after you eat a gigantic meal... do something, even if it's tap your leg.

haha i feel you on that, same situation here xcept about 8-9% right now
would be interested to know more about this...good replies/link so far, very interesting

i have definitely noticed that after a huge meal my body temp gets raised ALOT.

yes sir... when I went to the chinese buffet the other week I must've eaten 3 plates. I was near the point of the sweating just sitting down.

Best thing to do after something like that is to just go for a bike ride or walk.

yeah my last major cheat was extremely carb heavy and within minutes of finishing there was sweat on my face and i had to strip down to shorts and tank top lol. felt like the biggest fat slob, my gut packed full, sitting there sweating feeling/looking like i ate a cinderblock haha. been 2-3 weeks since then and i have had no desire to eat like that again. after so many times of overstuffing im losing the desire to do that completely.

I am in the same boat, since my show I kept over stuffing myself like once or twice a week, but now I am getting over this lol

[daYDreAmErX]

Same here. If I binge/cheat (or just go for a huge meal with friends.. something that lasts long enough so I get a lot of food in) I cannot have a good night of sleep. My body temp is high, I'm sweating, I have nightmares, I'm shaking...

Normal ?

[obesebeast]

usually if I go 10+ days without a cheat and then go on an epic binge like that, i end up passing out from the insulin spike and salvage some calories as a result

I once did the dominos 5-5-5 deal all for myself and downed all 3 within the hour. It was for a CKD refeed after a 7 day depletion, good times.

Yes - autonomic system upregulation. Very common. Most noted in young males -> especially those who are 'non-thrify' in their metabolism.

Often absent as you get older and fatter.
And also less common in females... :o

>> You be lucky as it = more energy 'wasted' and less 'waisted'.... :p

[caa5000]

if you're asking if some of the 3 sliecs of drunk canyon pizza you eat is going to be given off as heat? the asnwer is yes :) :)

hmm the same thing happens to me. after a big cheat meal i get really hot, heart speeds up, and i just feel crappy. so this is a good thing?

[SDC77]

Sucks for you guys. I feel like Superman after a ginormous meal of crap foods.

[Emma-Leigh]

^
yup. T'is good....

If, on the other hand, you felt like curling into a ball and sleeping... That be a bad sign (sign of a thrifty metabolism storing fuel for the winter :o ).

(note: there are complicating factors - eg: high fat meal usually less thermogenic and more of the sleeping <- CCK = time to go nigh-nigh hormone.... high carb meal + some tryptophan from proteins also more of the sleeping due to tryptophan crossing BBB... )

[wobemaster]

yup, good ole thermic effect of feeding

Just something I have wondered for a while. In the middle of reading all my nutrition and chemistry books and can't find anything on it. Thanks guys.

i did a lot of studies on this because i had the same problem...lol.....when you consume for example 5 to 10 thousand calories in one sitting, your body can only digest so much of it then the rest you **** it out...dont get me wrong, your body will not use all of those calories abviously so some will be stored as body fat and some will be undigested...everyone is different so some might store more fat and some might not....If it was as simple as calories in = calories out, then i guess you can gain 3 pounds of pure fat in one day by eating 10,000 calories. So its not as simple as calories in=calories out.. a lot goes on i guess (ex..thermo effect...body weight muscle to fat ratio, phyiscal activity, and etc....) i think you can look this stuff on google but i read it of a text book...

[BecomeLegendary]

^^^ thanks for the above info man. I think it also just has to do with a lot of different separate factors. I just need to look into actual studies on it I guess.

[Tom Bro]

I definitely wouldn't recommend doing it frequently or over a long period of time. If the stomach is forced to expand beyond it's capacity frequently, there is increased risk of gastric rupture.
That being said, I'm sure with careful monitoring of the volume of food you're ingesting, such a thing could easily be avoided.

ever heard of competitive eating?

[Tom Bro]

So? Gastric rupture is one of the biggest risks of competitive eating.

[nick1990]

so let me get this straight; if you eat a much larger meal than you normally would, and then afterwords if you stay active, whether it be walking, biking, or even "tapping your leg", as i saw in another post, your chances of it becoming fat are significantly reduced?
If that is true, can someone better explain/show me studies as to why this is so?

[Emma-Leigh]

Depends on if what you do is 'subconscious' (meaning your body is naturally 'geared' to higher NEAT / energy wasting) or self 'initiated' (meaning you are forcing yourself to 'be active').

You could simply run a PUBMED search on NEAT and you'd find the answer you are looking for - but some references -

Nonexercise activity thermogenesis--liberating the life-force.

Levine JA.
Endocrine Research Unit, Mayo Clinic, Rochester, MN 5590, USA. levine.james@mayo.edu
Obesity occurs when energy intake exceeds energy expenditure over a protracted period of time. The energy expenditure associated with everyday activity is called NEAT (Nonexercise activity thermogenesis). NEAT varies between two people of similar size by 2000 kcal day(-1) because of people's different occupations and leisure-time activities. Data support the central hypothesis that NEAT is pivotal in the regulation of human energy expenditure and body weight regulation and that NEAT is important for understanding the cause and effective treatment for obesity.

A NEAT Way to Control Weight?
Eric Ravussin
Why do some people remain slimmer than others? The answer may be in the amount of time lean individuals spend fidgeting, standing and walking around compared with sitting still. As Ravussin explains in a Perspective, a followup study by Levine et al. now pinpoints sitting as an important culprit of weight gain. Just sitting for 2.5 hours less each day would result in an extra energy expenditure of 350 kcal/day, which the authors calculate could translate into preventing the gain of extra pounds.

Central neural and endocrine mechanisms of non-exercise activity thermogenesis and their potential impact on obesity.

Novak CM, Levine JA.
Mayo Clinic, Endocrine Research Unit, Rochester, MN, USA. novak.colleen@mayo.edu
The rise in obesity is associated with a decline in the amount of physical activity in which people engage. The energy expended through everyday non-exercise activity, called non-exercise activity thermogenesis (NEAT), has a considerable potential impact on energy balance and weight gain. Comparatively little attention has been paid to the central mechanisms of energy expenditure and how decreases in NEAT might contribute to obesity. In this review, we first examine the sensory and endocrine mechanisms through which energy availability and energy balance are detected that may influence NEAT. Second, we describe the neural pathways that integrate these signals. Lastly, we consider the effector mechanisms that modulate NEAT through the alteration of activity levels as well as through changes in the energy efficiency of movement. Systems that regulate NEAT according to energy balance may be linked to neural circuits that modulate sleep, addiction and the stress response. The neural and endocrine systems that control NEAT are potential targets for the treatment of obesity.

Role of nonexercise activity thermogenesis (NEAT) in obesity.

Kotz CM, Levine JA.
Veterans Affairs Medical Center, Minneapolis, Minnesota, USA.
Obesity develops when there is an imbalance between energy intake and energy expenditure, which can vary daily within and among individuals. High levels of energy intake and low levels of energy expenditure contribute to obesity, both together and independently. Energy expenditure from exercise associated with formal programs is encouraged for health and weight loss, but most individuals get very little formal exercise. Nonexercise activity thermogenesis (NEAT) is the cumulative energy expended through all other activities of daily living. It is highly variable among individuals; it is controlled by the environment and, possibly, neurobiologically. Mounting evidence suggests that NEAT is critical in determining a person's susceptibility to body fat deposition and is a major factor in human obesity. Recent research supported by the Minnesota Partnership for Biotechnology and Medical Genomics, a state-sponsored collaborative effort of the University of Minnesota and Mayo Clinic, is helping to define the complex brain regulation of NEAT and its role in obesity. This article reviews the evidence for NEAT and the impact of NEAT on obesity.

Short-term dietary compensation in free-living adults.

McKiernan F, Hollis JH, Mattes RD.
Purdue University, W Lafayette, IN, 47907, USA.
Evidence suggests that compensatory behaviors operate in infants and pre-school children, such that the high variance characteristic of single eating occasions is much reduced over the day. However, the concept has not been fully explored in adults. The present within-subject, observational study investigated short-term dietary compensation patterns in fifty, weight-stable, normal weight (n=27), overweight (n=14), and obese (n=9) free-living adults (11 M, 39 F; age 30+/-11 y; BMI 26.3+/-5.9). Twenty four-hour diet recalls were obtained for 7 consecutive days, by the multi-pass technique. Each 24-h period was divided into 7 eating occasions. The coefficient of variation for energy intake was calculated for each adult, for each eating occasion, and over each 24-h period. Sub-group variability was assessed by BMI and frequency of consumption of sweetened energy-yielding beverages. The mean coefficient of variation for energy intake for the 7 eating occasions was 110.5%, compared to 28.9% for the day as a whole. Correlations between energy intakes at successive eating events were uniformly negative. No significant differences were noted in the sub-group analyses. Significantly greater variation in energy intake was noted for snacks compared to meals (P<0.0001). These data suggest that adults regulate energy intake over a 24-h period more closely than they do at individual eating occasions, similar to the pattern previously observed in children. Further studies of compensatory responses by larger sub-groups of individuals at risk for weight gain are warranted.

I'll be sure to remember to run a pubmed search next time.

If I am understanding this correctly, does the fact that I can NEVER sit still mean I have a higher NEAT than normal? By never sit still I mean I am constanly shaking one or both legs, getting up walking around for no reason, then sitting down to shake some more. In all honesty I am laying in bed right now and haven't been able to stop moving around for the past hour. (Blow because I can't sleep.)

Either that - or you have thyroid disease.... or worms....
Personally - I like the worms hypothesis (< and, you know, it also helps with the weight loss thing ;) )...

:p

seriously though - yes... your NEAT is higher... it is not a 'static' thing though - it is simply the energy output of movement not associated with exercise... eg: washing the car, talking, cooking, reading, taking a bath, blinking etc... <- all of these are examples of 'NEAT'.

And there are those who naturally have 'high' NEAT (eg: you) and those who's bodies, for reasons only known to their genetic make-up, tend to be pre-programed to 'slow' -> hell-bent on conserving every last drop of energy they can (eg: me :o ).

But... hey.... in terms of evolution ->> should we ever enter another ice-age or endless drought.... My butt would last longer than yours... :cool:

:rolleyes:

=o. I guess one can still get past that regardless as I used to be obese, I assume 10k cals daily can overcome all =/. I also find the leaner I get, the less I can control (stop) myself from shaking my legs (my friends call them the dual pistons when both get going, and man they get GOING when I actually become concious of it) , fidgeting, doing stuff etc. It gets really annoying to people who sit around me =/.

LOL. and i thought i was the only one having these experiences. ice bath anyone?LOL
