Food items are measured in calories of stored energy because our bodies burn energy in amounts that we can also measure, and that measure is in the form of calories. A calorie is typically known as the amount of energy required to raise one gram of water one degree in temperature.
Much of the energy stored by our bodies is designed to be released fairly quickly from our muscles and from our deposits of fat. Muscles release this energy quickly so we can (historically) chase and catch prey, and also to elude predators.
From the calories of what you eat.
Nutrients important to human metabolism include the essential vitamins and minerals as well as a source of energy that is found in calories from sugar and fats.
The human may increase its metabolism somewhat. Generally speaking, if you do the work to vibrate or whatever, then you burn the calories. If a machine does the work, the machine burns (its) calories -- which is not so helpful for the human.
No, people of different races do not have different fat burning metabolisms. We are all human and metabolism food the same way on the inside -- calories in, calories out.

Exercise can increase your metabolism by burning calories and building muscle, which can help you burn more calories even when you're at rest.
yes they do, it depends on their weight and their metabolism
Heat is measured in calories or joules.
Metabolism
kilocalorie (kcal)
The human body produces electrochemical, kinetic, and potential energy.
The energy a human can receive from food is measured in calories, with the average adult requiring about 2,000 to 2,500 calories per day, depending on factors like age, sex, and activity level. Each macronutrient contributes differently: carbohydrates and proteins provide roughly 4 calories per gram, while fats provide about 9 calories per gram. The body converts the energy from food into ATP (adenosine triphosphate) to fuel various physiological processes. Ultimately, the energy received from food supports daily activities, metabolism, and overall health.
