I have the slightest clue dont know nothing about that

The most popular method is the Body Mass Index (BMI). It is a number calculated from a person’s weight and height. It doesn't directly measure body fat, but still provides a good estimate.\n\nThere are many BMI calculators available on the Internet. For an example of one (for teens and adults), visit the CDC site sourced below. If your question relates to the formula behind the BMI, visit the second (for adults) or third (for teens) sites sourced below.

It depends on your height, weight, age, and sex.  There are several online calculators that ascertain your particular basal metabolic rate, or how many calories YOU burn in a day.  Once you find that out, you can use that number to lose weight by creating a calorie deficit by eating x number less than your bmr and/or burning them off through exercise.\nHere is a link to a metabolic calculator-\nhttp://www.internetfitness.com/calculators/bmr.htm\n3500 calories equals a pound.  Consume 3500 more than you need/burn, you will gain one pound.  Consume/Burn 3500 less than you need, you will lose one pound.  Aim for 500 to 1000 calories less than your bmr to lose 1-2 pounds per week.  Any added exercise can only increase the results, so exercise away.

Calories are energy, essentially. In fact, they're also a unit of measure of energy. \n\nThe human body only needs a certain amount of calories to carry out life processes and fuel the body. When you consume in excess, the calories are stored as fat and other unhealthy compounds.

When a person sleeps or in resting position, the amount of calories he or she burns per hour is equals to his or her weight. For example, a person who weighs 50 kgs, burns about 50 Cals per hour while sleeping.

As Beare85 said, the matter comes in as nutrients or food. Metabolism consists a series of reactions that happens in the body and in cells, taking in food (potato, beef and so on), brakes them down into the smallest biological molecules (particles such as proteins, carbohydrates, fat, and other minerals and vita mines, while storing the energy of those bonds), then uses them as building blocks for their functions. In the body, a lot of the breaking down happens in the digestive system, and is spread through the body in the blood. Cells absorb nitriente mostly as building blocks already. Cells are mostly proteins, lipids (fat) and water. It all comes from food.

Yes, Tredmills and Bikes either up up right or recumberant are calibrated with equations to estimate approximate caloric expenditure as long as your are putting you age and height in. They are pretty accurate as long as you program them correctly.

There are a few formula we use when we work in a clinical setting.  For a community setting, here is a simple formula we post on our website.\n\n(Body Weight (lb) x 15) + (moderate activity (mins/day) x 3.5) = BMR in kcal\n\nFor instance, you weigh 140 lb and you perform 20 mins of moderate activity every day. BMR of this example = (140 x 15) + (20 x 3.5) = 2100 + 70 = 2170 kcal.\n\nTake care :-)

I know the average for adults is 6500KJoules but you would need to convert that to calories sorry! Its called something like the "energy of basal metabolism" if its just the basic needed to keep a person alive so if you search for that you can find what it would be for women.

Metabolism can be sped up naturally by eating less more often...spread out your portions through out the day to sped up your metabolism.

fat is turned into energy and consumed by your body.

Peanut butter, cornbread, chicken and dumplins, biscuits, they will all put on weight.\nAs far as metabolism, be patient It'll slow down soon enough!

ya, u probably have a fast metabolism - so tell people that! A fast metabolism is when ur body is able to digest food really quickly and hardly makes u put on weight...i have a fast metabolism and it suits me just fine! eating anything and everything i want anytime without worrying of putting on weight. Just as long as you eat enough for your body to get all the essential nutrients and aren't concerned about gaining extra weight or thinking ure fat when ure actually not, u don't hav a problem at all!

*Total Energy Requirements (kcal/day)= Basal Energy Expenditure + Activity Energy Expenditure + Specific Dynamic Activity\n\n\nWhere:\n***Basal Energy Expenditure in males: 66+ (13.7 x weight in kg)+(5 x height in cm) – (6.8 x age in years)\n***Basal Energy Expenditure in females: 655+ (9.6 x weight in kg)+(1.8 x height in cm) – (4.7 x age in years)\n***Activity Energy Expenditure:\n(Sedentary= 400 to 800 kcal/day)\n(Light work= 800 to 1200 kcal/day)\n(Moderate work= 1200 to 1800 kcal/day)\n(Hard work= 1800 to 4500 kcal/day)\n***Specific Dynamic Activity= Basal Energy Expenditure x 0.10\n\nIf you prefer avoiding calculation just use a Total Energy Requirements calculator on-line:\nhttp://www-users.med.cornell.edu/~spon/picu/calc/beecalc.htm

Try the BMR/RMR and activity calculators at this website:  http://www.caloriesperhour.com  You'll need to input your sex, weight, height and age to figure out your RMR and BMR.  This is the absolute minimum number of calories you should eat.  Those are the calories needed just to be alive.  There's some good explanations on the website.\n\nAnother good website is http://www.sparkpeople.com

The only way to jumpstart your metabolism is to exercise.  You will start building muscle which means you will eventually have to burn more fuel to do the same movements.  Also, your body will actually constuct more capillaries inside of your muscles so that it can get fuel there more quickly.

Metabolism is a measure of how quickly chemical reactions take place in the body. (Since these require energy it is often referred to syonmously as energy use). \n\nDifferent people have different metabolic rates, mostly based on the proportion of their body weight that is made up of lean muscle mass which one of the most metabolically active in the  body (the nervous system and the liver are more active but make up smaller percentages of the body so their effect is neglegable by comparison).\n\nWhen energy is generated from food storage (glocose or fatty acid chains), a couple of different "metabolic" pathways can be taken. First gluclose can be converted anerobically into pyruvate and two high-energy ATP andeosene-tri-phospate molecules. Then it may be further processed in a mitochondria in a process called the Krebs cycle into ATP, CO2, and water. Fatty acid chains, unfortunately, can only be processed aerobically. After some pre-processing they can also enter the Krebs cycle.
