Calories
The value of the energy of food is measured in units known as calories. The moderate physically active person requires almost 2500 calories per day to maintain moderate weight, and the normal physically active woman requires almost 2000 calories per day. Such an amount of calories might sound high, but it might be simple to get if you consume certain kinds of foods. For instance, eating a big takeaway hamburger, milkshake and fries can make almost 1500 calories and it is just one meal. Another situation is that various people who are not active physically, so high amount of calories they eat end up stored in their body as fat.
