If you eat a pound of food do you gain a pound?



Because I have weighed myself after eating and I didn't get any noticeable weight gain.
 
Are your posts always this random?

For your question, IN theory you should, but I never tested it.
 
I think to gain a pound you have to eat 3500 Calories.
 
Did you just see that episode of Brainiacs? They did something like that. :)

No, because you lose an ounce just by chewing. (granted, they only tested it once).

Unless you sent it down a food-tube.
 
Simple answer - no. You're going to use up the energy from that food, but energy conversion is the human body is not 100% efficient.
 
Yeah but his question was "if you weight yourself right after eating a pound of food, should you weight a pound more ?"

Something I have always wondered after my fourth helping of lasagnas :lol:
 
There was this quiz show program on TV, well not really a quiz show (Don't know you to name it, It was like Fear Factor or these programs where the constestans have to complete tasks rather than ask questions) Well, the task was to gain about 1 Kg. (2.2 lb) in ten minutes, or so. So the contestant are weighted before, they start eating and drinking compulsively and they, more ofen than not, win the contest after being weighted. The trick in the test is to dirnk a lot, if you drink one litter of water, you win one Kg. and the contest. ;)

But then, is what perfection said. You breathe and you inhale O2 and exhale CO2, here it oges a bit of your weight, then you do # 1 and # 2 and you lose a bunch of the weight you won, if not all, If you are over 25, It is never all of it :(
 
Immediately after you eat, you should have gained about a pound. But obviously, your body will consume some of the energy from the food, and part of it will be expelled as waste.

In the long run, you have to eat about 3000 calories to gain a pound.
 
How much you gain from eating a pound of food depends on what you eat. Some food provides less energy than it takes to chew and digest.
 
Your body uses energy constantly. E=mc^2, so if you plug the numbers in, you'll find that you radiate enough energy per day to power a small city for a month. That's where they got the idea for The Matrix, and also why you can't run a perfect fridge (2nd law of Thermodynamics).

Seriously, you could probably work out a more precise number from you body temperature (one would imagine that chewing uses much much less energy than the rest of your body does) and use E=sigma.T^4 or something, then work out how much energy is released per pound of food that you eat, take one from the other, and you'll probably get 3000 calories. I'll have a go some time, it sounds like fun!

Yes, you do gain a pound, but you only keep the portion of the food that is digestible and absorbed. Immediately after a meal, you should gain as much weight as the food weighed. However, a pound of food is a lot, so I doubt you will notice much weight gain immediately after a meal.
 
There's also the fact that force does not have to be equally distributed. Although gravity points down, it is rather impossible to treat a human as a point system in a dynamic process such as moving.

I think it's called a feeding tube.

But I do think that you gain the pound while your body starts digesting it. But after your body takes what it needs, you only gain 1/4 to 1/2 a pound.

Nahh! Water will screw it up, most of the loss in mass is through evaporation and sweating and pissing. Unless you have a way for measuring the water content of the food substance before consumption maybe feed eW0054 only crackers, and water is consumed seperately. The bodies heat distribution is unequal, hard to get the mean radiated temperature of the body unless we put the poor eW0054 in a self contained insulated container with a constant temperature and volume, energy radiated is temperature raised in container. After the experiment we can then accurately how much weight was gained. Of course we have to repeat the experiment several time over to ensure eW0054 gets only the correct results......Heheheh
 
I think eW0054 just has an unreliable balance. I have one that I can make swing ten pounds in either direction just by where I center my weight.
 
To store food in your body, there are three mechanisms.

In your belly, etc. If you eat a pound of food, you will weigh a pound more for awhile.

As glycogen (in liver, muscle cells, etc.): if you're low on glycogen and eat a pound of bread (or other carb), your body will store some of the sugars. It takes (I believe) 3 grams of water to store 1 gram of glycogen. So, in fact, you can gain more than a pound (if you drink enough water).

As fat. Your body will convert the food to become fat. Since your pound of food is probably not a brick of butter, some energy will be consumed storing the food, and the total amount of fat will weigh less than a pound.
 
Yeah, I know. And if you consume lots of proteins, your liver will start to make more 'protein-digesting' enzymes (which are made of proteins) and you can actually store protein in the form of these enzymes (at least until your liver gets 'full' of them).
