What powers weight loss??? (what is the science)

Well when you work out the cells in your muscles need energy to contract, that energy comes from either your food or your fat. The formulas for them are a little different but essentially you are converting cellulose (C6-H12-O6) and oxygen (O2) into water (H20), carbon dioxide (CO2) and energy. If however you can't sustain the cells with enough oxygen you will produce carbon monoxide (CO) and a bunch of other nasty acids which make your muscles hurt, in my country it translates to "milk acid" not sure what it's called in English but if you have bad constitution you will get it. Now there's several different forms of fats in your body and they all contain various amounts of energy percentage and other chemicals like drugs and medicines. The reason why it's often harder for women to loose weight is because their fat molecules are mostly long chains who take forever to convert into energy, while men has very short. The reason to this is that the females carry a baby and needs an energy storage, you see the same phenomenon in other animals.

Here's the science:

a Carbohydrate is in a chemical form of C6 H12 O6 as mentioned above. now add that thing is the Bio Fuel of our body used by the Mitochondria. add that Up with Oxygen and you get H2O+CO2+HEAT+Energy.

Now there are 2 types of muscles 1.type is High Power 2nd type is High Stamina. it depends on the cell composition whether there are more mitochondria or not

The High Power is a Big muscle as it relies on fats inside it to do more non-aerobic works (works that consumes less oxygen)

the High Stamina type of Muscle is relatively thinner as it does not have that much of fats inside it and consumes more oxygen.

consider the difference of a weight lifter and a Marathon runner. (PS: the "High stamina" and "High Power" naming system is just my Own words to explain it to you.)

the type of muscle you have depends on your activity, as animals are basically Adaptive organisms. so if you'd like to be thin, do more of Aerobic Exercises one that'd feed more Oxygen to your muscles. Examples are cycling, Jogging, anything that keeps your heart beat Up for Extended period of time but does not strain your muscle. Also make sure to maintain a good Rhythm of breathing

Moreover, Fats are excess energy store.

after you eat and excess amount of calories, your Liver will convert them into a longer chain of Sugar one that is longer than Carbohydrate (which I forgot to mention is another type of sugar) this longer-than-carbohydrate sugar is now called fat. Males and Females do have this Fat.

Now the reason why Females Get Fat? is because Males and Females have different Major Sex hormones due to the difference in their sex organs.

Males produce Larger Testosterone compared to little amounts in Females

Females Produce Large amounts Estrogen and Progesterone while Males produce almost negligible amounts of these (just google the funtions of Estro and Proges)

Now what's significant about that is the Estrogen , since Estrogen Encourages FAT storage. THis is to prepare the woman for Pregnancy.

Fats are converted back by the liver into Carbohydrates to produce energy whenever the body lacks any other source of Fuel.

In a dessert where you only have A tank of water and nO Food for 30days (you would survive by:)

1. The Body Consumes every food you ate by the last 4hours
2. The Body is now hungry and brain releases hormones to break down fats
3. those fats are then converted to energy and a bad by-product which is ketone.
4. when you Run out of fats, your brain will activate another hormone.
5. these hormone will now break down muscles in order to get their C-H-O content (the result would be the same as a malnourished child - muscle wasting or Kwashiorkore looking
6. since muscles are made up of C-H-O-N there would be a waste chemical of Nitrogen.
7. the C-H-O however will be again converted to sugar then to calories in order to fuel up the body.
8. now after 30days even if you still have water, you might actually die because of the Nitrogen and Ketone build up.

Well the fat is burnt from working out

it is a very complicated system of systems: but an interesting documentary is on hulu
