Your body does one of two things. It will either store the calories for later in the form of fat or it will use them right away.
Your body uses calories for everything, pumping your heart, digesting your food, and etc. It can be minor actions like typing, changing the channel, talking, eating, standing, and etc. Everything you do needs calories.
calories are energy. food contains calories, so when you eat food, the calories within the food power your body.
Some people have a high metabolism which makes their bodies eat away calories fast and some people have a low metabolism which makes their bodies eat calories not as fast . too many calories = stored up fat = larger person.
Most of the calories consumed through food are burned through your Basic Metabolic Rate. This is the energy required by your body to simply stay alive, and accounts for between 50% and 80% of the bodies total energy expenditure.
Water weight has NOTHING AT ALL to do with the calories in food. Calories reported are the calories in the FOOD. Water HAS NO CALORIES. Get your head on man.
Surprisingly, you will gain weight if you do not eat enough of quality calories to sustain your body and its activities. That is because, biologically, our bodies are programmed to preserve fat if they perceive a shortage of food (starvation).
calories give you energy and provide nutrients to help the body
Fats are not in calories but in food. Food nutrients (and fats are one of them) usually have calories.
Beer calories are not equivalent to food calories. Beer contains empty calories, meaning they provide little to no nutritional value, while food calories come from a variety of nutrients that are essential for the body's functioning.
It is determined by the number of calories. 1000 Calories equals one kilocalorie and a daily in take is 2, 500 Calories.
Food a contains 150 calories in three forth serving. That makes 200 calories per serving. Food B contains 250 calories per two third serving. That makes 375 calories per serving. So food A has got less calories per unit serving as compared to food B.
Calories are only a measure of how much energy you can get from a nutrient or a food source. The more calories you get, the more energy you can burn. However if you burn less calories of what you ingest, you get stored fat. Calories are how we measure energy from foods for our body. When we get more calories than we burn, we store the extra in fat cells. This is how we gain weight. When we eat less calories than we burn, we use the extra calories tored in fat cells. This is how we lose weight.
