In referring to the energy content of foods it is customary to use the “large calorie,” which is equal to 1 kilocalorie (kcal). Every bodily process, including the building up of cells, motion of the muscles, and the maintenance of body temperature, requires energy, which the body derives from the food it consumes. Digestive processes reduce food to usable “fuel,” which the body “burns” in the complex chemical reactions that sustain life. The amount of energy required for these chemical processes varies. Factors such as weight, age, activity, and metabolic rate determine a person's daily calorie requirement. Nutrition experts have computed daily calorie requirements in terms of age and other factors. These tabulations serve only as guides; they cannot, of course, embrace all individual variations.

From its daily intake of energy foods, the body uses only the amount it needs for energy purposes. The remainder is stored as fat. If the average adult consumes more calories than the daily requirement, he or she will gain weight. However, if consumption is less than recommended daily requirements, the body will supplement its energy sources by drawing upon stores of fat and the person will lose weight.

Patient discussion about cal

Q. In which sports do you burn the most calories? I heard that in a spinning session you can burn up to 1000 calories and that Bikram yoga is also very good for burning lots of calories. Do you know of other sports?

A. Running and cycling are considered high-expenditure sports. Generally, the higher you get your pulse during the exercise the higher your calorie expenditure is. However, the burning fat is optimal at a certain pulse, usually not the highest you can get yourself to.

A. Alcohol carries about 7 Kcal per gram. 1 gram of fat gives 9 kcal & 1 gram of carbohydrate gives 4 kcal. but vast amount of alcohol can suppress the need for food, so they can pass out every afternoon and forget eating. obesity is a better situation. trust me.
