well you can stay at maintainance at burn 500 cals a day n you will lose a pound every week.
2nd ques when you are burning fat look for when thing when you go to toilet to pee you will notice something white in your pee is like chicken fat thats how some of your fat comes out n some as a sweat. because when i did a diet few years back when the white thing came in pee i got scared that its something serious but found out its nothing just fat so a doctor knows best.
So THIS is why drinking water helps you lose weight...the more water you drink, the more you pee, so the more fat can leave your body...good to know :huh:
Seriously, you'd think that with all the resources we have available to us, people would not be THIS misinformed. And that doctor...how did he/she ever get a license to practice medicine?! :grumble:
They bought their license on craigslist...duh??!!??!!:laugh:0 -
I think every pound you lost in December was found by my thighs.
This is hilarious!! :drinker:0 -

My husband loses pounds all the time - every time he sits down in the car they fall out his pocket and get lost in the crumby pit beneath the seat0

Pounds of fat are NOT converted into energy. One of the rules of science is that matter can not be created or destroyed, only changed in form. The only way matter can be DIRECTLY converted into energy is through Nuclear Fusion or Fission, which itself takes massive amounts of energy to initiate - it's how our sun works after all.
Potential energy is stored up in your fat cells in the form of various chemicals, and the fat cells grow larger to retain them. When those cells are tapped for their energy (from dieting or whatever), they give up those chemicals, a reaction takes place, and the stored-up sugars are released back to your bloodstream for use.
So where do the pounds actually go? It leaves your body the same way all weight leaves your body - fluids and solids are passed out through sweat, urine, or excrement. Sounds gross, but there it is. You don't actually "lose" any fat cells. They just shrink.
So thinking "I have to convert all this weight I'm carrying around into energy" is not really true. When you build up a calorie (a.k.a. energy) deficit, it signals your body to use the stored-up potential energy. In the process, it releases the extra mass you have and converts it into waste

The original poster asked some interesting questions, and I like the way she thinks.
A "heat engine" takes in heat and converts a portion of it into mechanical work. When nutrient molecules in the body are combined with oxygen ("burned"), that's an exothermic reaction; it produces heat. Muscle cells use that heat energy to do work. The whole human body can be usefully regarded as a heat engine.
And yes, calories *are* energy, rigorously and exactly. A calorie is the amount of heat energy required to increase the temperature of a gram of water by a Celsius degree. (A nutritional calorie -- the sort we all talk about here -- is 1000 calories, as defined. It is also equal to 4186 joules, which is the work done by one newton of force over a parallel displacement of 4186 meters. A "typical" person weighs about 667 newtons, and can be lifted a little over six meters, straight up, by a nutritional calorie of mechanical work.)
A pound is lost when a pound of stored nutrients in the body (hopefully, fat) has been converted to ... well, not just energy. If an entire pound of fat were all converted to energy (according to E = mc^2), a dieter would be like an atomic bomb. But, as another commenter pointed out, chemical bonds in the pound of fat are broken, some of it is oxidized, heat is produced by that reaction; most of the rest of the broken-down nutrient molecules become waste and are eliminated in the same way as any food waste. The energy required by your body is supplied by the food you eat; if you don't eat "enough," you're in a calorie-deficit situation, and some stored body fat is internally "eaten" as well. As the OP said, about 3500 cal of deficit is equivalent to a pound of fat; as for WHEN this happens: as soon as your body requires a single calorie more than you've eaten, 1/3500 of a pound gets burned. When your cumulative deficit reaches 3500 cal, a full pound will have been used. (For the elimination of the unburned waste, I suppose there's a time delay measured in hours.)
But, in any case, that pound of fat didn't turn into nothing. A very small fraction of it is turned into heat and used by your muscles; the vast majority is turned into feces and urine, and returns to nature in the usual ways.
People ask me from time to time how much weight I've lost. Of course, I tell them that "lost" is probably too strong a term. I pretty much know where all of it is. Most of it's at the grocery store; quite a bit is at Burger King and Taco Bell and so on. I could go pick it up at any time. So, it's not really lost; it's more like "misplaced." I hope to leave it that way.
He's probably a scientist. Amazing. Best answer, besides the white stuff in your pee.0 -

I really like this response, as well as the other two more scientific replies. I think it's important to note that, yes, fat does eventually leave your body as waste (after we suck all the 'good stuff' out of it). TBH, while the original response in this thread gave me a bit of a chuckle for various reasons, it wasn't as completely inaccurate as people here have made it out to be. I was happy to see people answer the original question with good information instead of mockery. I haven't been on the boards in a while, and I was taken aback at some of the nastiness disguised as humor.

Sigh. You are all SO misguided. Poor heathens.
Fatness is a punishment from the Divine Flying Spaghetti Monster. We have all displeased him in some way. And the only way to lose weight is to perform the appropriate rituals of repentance. In his Infinite Wisdom, our deity has provided several different rituals for those of different temperaments. You could practice the Treading of the Mill, or the Holy Contortions of Yoga, or submit yourself to the Torturers (sometimes called "Aerobics Instructors") at one of his Sacred Temples (also known as "gyms").
If your Ritual Humiliations have found favor with His Noodly Goodness, he shall visit you in your sleep and shave the pounds from your body with his Holy Cheese Grater.
I hope this has enlightened you all. May the Sauce be with you. RAmen.

Although I think the poster of that one took the converted into energy a little to literally. LOL I'm sure no one assumed a direct conversion of matter to energy... that would make for a lively Weight Watchers meeting. 0 -

Lol, so thats why America has to be overweight....huh, if we were all to lose weight, the earth would be thrown off it's axis and all hell would break loose. Now THAT is scientific! :laugh:
It also explains global warming. Yep, it's all our fault. MFP-ers and dieters are creating too much heat by burning all this fat, and now the ice caps are melting.0 -
i'm sure this has been said over and over during this 6 pg thread, but your number of fat cells don't reduce, just the SIZE of them does! so, as you burn off that fat for energy, the cell size gets smaller. so, if you have 100 fat cells at 200 lbs you will still have 100 fat cells at 100 lbs, they have just shrunk a whole heck of a lot!
and to the girl who thinks you pee out the fat.... if you really do have white bits coming out in your pee, you need to see a doctor. we do excrete waste via urine and poop, and some people might notice fatty or greasy poop, but this is not the fat you are breaking down and expelling. this is fat your body is not able to DIGEST when you consume it........ it's often a sign of a metabolic or digestive disorder.........0 -

OK, I am sitting here at work and laughing outloud at some of these reponses... Burning even more calories, I might add.. and hopefully not getting fired......:laugh:0 -
I always thought I was sneezing out my fat when my sinuses were acting up.......
Excellent, then!! My sinuses have been driving me crazy, lately!! Bikini season, here I come!! :laugh:0 -
Wondering if the "white stuff" she sees in the toilet might be cervical mucus... lovely stuff. Yum!0

Personally I prefer the Dr Who version. Your fat leaves your body as an Adipose a new baby life form and is beamed to another planet to grow and mature.
Anyone who doesn't watch Dr Who google Adipose they are so cute.0 -
