by burning calories

you ever notice how athletes eat energy bars and stuff like that?

that's because those foods have lots of calories. When you eat you consume calories: a measure of kinetic energy. Your body uses up calories through physical activity. Even walking or lifting a finger requires energy. Without calories, you would be really tired and sleepy.

What type of energy does a candlelight have?

There are two kinds of energy involved in candlelights. Firstly, a candlelight uses chemical energy to burn. Chemical energy is when something consumes fuel to produce energy, a candlelight uses a wick and the oxygen in the air to burn. Candlelight also gives of heat energy, which is the transfer of energy from one body or system due to thermal contact.


Why do people use more energy when they work rather then when they sleep?

For the same reason that a car burns more gas when it is driving then when it is sitting still at idle. When you work you burn calories. When you rest you still burn calories but not nearly as much. If you want the fire to burn hotter you need more fuel or energy. Sorry it's not a technical answer but it still explains why.


What two types of energy are involved when friction causes an object to heat up?

I think it is kinetic and heat energy. An example of this would be if you were sliding down a rope and got rope burn- the kinetic energy causes you to move and friction is caused between your body and the rope and thus causing heat that equals rope burn. Hope this helps :-)


How does the law of conservation of energy relate to eating and caloric intake?

The law of conservation of energy states that energy cannot be created or destroyed, only transformed. When we eat food, we consume a certain amount of energy (calories) that is then used by our body for various functions. If we consume more calories than we expend, the excess is stored as fat, whereas if we consume fewer calories than we expend, we lose weight as our body uses stored energy.


How does your bodies store unwanted energy?

The body stores unwanted energy in the form of fat. When we consume more calories than we burn through daily activities, the excess energy is stored in fat cells for later use. This can lead to weight gain and health issues if the energy intake consistently exceeds the energy expenditure.

Is fiber stored for when you have no carbohydrates to burn?

No, fats are used as energy once your body has no carbohydrates left to burn.


Does your body burn protein?

Yes, the body can burn protein for energy in the absence of carbohydrates or fats. However, the body prefers to use carbohydrates and fats as its primary sources of energy. When protein is burned for energy, it can lead to muscle breakdown and is not the body's preferred method of obtaining energy.


Does your body burn protein for energy during physical activity?

Yes, the body can burn protein for energy during physical activity, but it typically relies more on carbohydrates and fats for energy. Protein is usually used for building and repairing tissues, not as a primary source of energy.


What term is defined as the body ability to burn nutrients to provide energy?

Metabolism.


How do body get energy from food?

When u eat food your body takes out the calories to burn. That is wat produces energy. However if have to many calories at one time your cant burn it fast enough and will eventually becomes fat


How does exercising burn fat?

Because the body will have to release the fat for energy, which is then burned by mitochondria in the cells for energy to exercise.


How does human body use carbs?

Quick energy...they burn faster than protein and fat.


When people die do your bodies still burn energy?

No. once your body has shut down, it no longer requires energy, and will lose every type of energy over time. It may burn a small amount in muscle spasms, however.


Does the body continue to burn energy after you stop exercising?

Your body consumes energy all day and all night, whether you exercise or not, until you are dead. When you exercise, and for a short while thereafter, your body burns more energy than normal.


How do muscle stimulators burn calories and contribute to weight loss?

Muscle stimulators help burn calories by causing muscles to contract, which requires energy. This energy comes from burning calories stored in the body, leading to weight loss over time as the body uses up its stored energy reserves.


What 80.38 fat burn means?

"Fat burn" refers to the physiological process by which the body uses stored fat as a source of energy. This process occurs when the body's energy demands exceed the immediate supply of glucose (sugar) available for energy. When this happens, the body starts breaking down fat molecules from fat cells (adipose tissue) into fatty acids and glycerol. These fatty acids are then transported through the bloodstream to cells where they are used as fuel for energy production.
