When you lose weight, where does it go?

Answer 1

Just to clarify something right now- fat does NOT become sweat as it's burned. Sweat is produced as you exercise to help cool the body's temperature via evaporation. This is controlled through completely different mechanisms.

To reaffirm my point you can burn fat without ever breaking a sweat. This would be from caloric control. Basically if you consume less than your body uses for energy everyday it will eventually turn to fat to get what is lacking in your intake. Keep in mind fat is not the FIRST reserve energy your body uses. That is actually a carbohydrate called glycogen.

Once you've used up glycogen your body turns to fat. Fat storage is infinite, meaning that your body can keep packing it on as long as you over consume. Fat is also a much more efficient means of storing energy than glycogen. For the same weight fat yields more than twice the amount of energy than does carbohydrates.

So where does it go? Fat cells have storage pockets called vacuoles that hold the stored fat. As you need the energy your body empties out this vacuole, though the cell remains, and converts the fat into a burnable energy source. Ketone bodies maybe a familiar term. These are made from fat in the liver and basically act as a sugar for cells that prefer or can only utilize sugar in metabolic pathways (such as cells of the nervous system). Other cells can metabolize the fatty acids directly.

When you use up these fat stores the fat cells shrink, because the vacuole no longer has the fat inside it, but they do not disappear. That is one reason why it's so much easier to gain it back.

The fat turns into the same basic things our other energy sources turn into, carbon dioxide, heat, and metabolic water (which, by the way, is not the same thing as sweat!)

Answer 2

We lose weight when we eat food in limit and doing proper exercise.And 70% of our weight get proper shape and size & 30% of weight come out of our body through sweat.

Answer 3

It is just an energy. When glucose energy is broken down, it breaks up into sweat. This is formed when we exercise or do pranayams. It contains salt. The acid when goes into our body through pesticide vegetables, cold drinks etc. reacts with base glucose in our body.

As all the Class 8 people know, but seniors don't that Acid + Base = Salt + Water (sweat contains 40% water). That's you answer.

Answer 4

the answer to this is simple. The weight is caused by excess fat and calories stored in our body and in the omentum. When we exercise, the calories get burnt releasing water and carbon dioxide and some other elements. The water is used for sweating and other processes, carbon dioxide is released and other elements are exhaled and given out as waste with sweating etc.

Answer 5

when you loose weight, then extra fat deposited in your body is converted into biological energy by the reaction of fat molecue with oxygen(the long process is given by some)which is used to support your extra activities & excercise & the body heat and the byproduct of it water, minerals & CO2 leave body in the form of sweat, urine & breathe out.

THUS IN THE PROCESS OF LOOSING WEIGHT MAJOR PART OF THE FAT MASS EXITS BODY IN THE FORM of SWEAT, URINE & BREATHE OUT & THE ENEERGY LIBERTED IN THE PROCESS IS USED TO SUPPORT YOUR EXTRA ACTIVITIES & EXCERCISE & THE BODY HEAT

extra weight in your body is like The extra fuel in a engine tank of your boat so which you think, if travelled with may cause the boat drowned into the water, for that you run the engine in idle mode for some time so that extra fuel is burned & now with lesser weight you have reduced the risk,

but if fuel is too less then you may starve for fuel while in return, so an optimum level is the best.not excess not less.

Answer 6

From the conservation of energy principle, energy can neither be created nor destroyed. It changes form fron form to the other. The energy required for the body is supplied through food. If excess energy is available it is stored in the body in form of fat and will be used when necessary. When you exercise this energy in the form of fat is used up to support the stress applied on the body.

Answer 7

when we lose our weight , we are actually losing fat in form of energy, when we work out our energy gets converted into sweat and heat energy.

Answer 8

Simple, matter is neither created nor destroyed; only transformed. In this case into sweat then into gasses through evaporation or merger with the air, adding to its humidity and pollution !

Answer 9

I think if any one loose weight by exercising the fat% of the body reduces and get utilised in muscle preparation.

Answer 10

It is burned as energy. When you exersise, and you haven't been eating alot, your glycogen (energy cells use) is used up. After that is used, your body resorts to using adipose (fat cells) fat as energy. Thee days people hold back on carbohydrates because they contain more glycogen than other foods. Therefore, it is harder to burn off all of the carbs you eat.
