NOT THINGS – THEY ARE A MEASURE OF FOOD ENERGY
- The definition of calorie (cal), or small calorie, is the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius.
- The definition of kilocalories (kcal), or large calorie, is the amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius. A kilocalorie is equivalent to 1000 small calories. Kilocalories are sometimes called “food calories” or simply shortened to “calories” when referring to the energy in food.
HOW TO MEASURE CALORIES
Yes you can read the label on the food. But before that .. bomb calorimeteris an apparatus that can measure heats of combustion, used in various applications such as calculating the calorific value of foods and fuels.
A CALORIE IS STILL A CALORIE FOR WEIGHT LOSS
Weight gain or loss is not primarily determined by varying proportions of carbohydrate and fat in the diet, but instead by the number of calories ingested. Changes in energy expenditure, which metabolic pathways are used and other considerations are quite modest when compared with caloric intake. Until high-quality, metabolic ward primary data become available indicating otherwise, a calorie is still a calorie. (American Journal of Physiology Study)
