>What are calories? Is it the amount if energy in a food?
You’re spot on with this. One calorie is defined as the energy needed to raise the temperature of one gram of water by one degree C. A Calorie (yes the capitalization makes a difference) is equal to 1000 calories, or one kilocalorie. 1 Cal = 1 kcal = 1000 cal.
>How does the body uses calories, burns calories
Generally, most of the calories you use are consumed simply by existing. Involuntary actions, such as breathing, your heart beating, or conscious actions, such as walking, orr turning your head, or moving your fingers also burn calories.
>how does excess calories becomes fat?
Of the three main sources of calories the human body uses, fat has the highest energy density, or calories per gram. So our body takes any excess calories and turns them into fat for storage and use later.

The physical size of a food as compared to a other doesn’t have an effect on the Calorie content. It has to do with the composition of ingredients in the food. Foods that are low in calories are beneficial for people that are trying to lose weight because they physically make you feel full, but you get much less calories from your food. This will force your body to collect the energy it needs from within rather than an external source.
