Humans have long lost the hunger instinct present in animals. Instead, we’ve developed another strong habit known as over-consuming. It’s nothing to be ashamed of, but it is important to admit to ourselves that we eat and consume more than our bodies need. For many people, overweight is clearly linked with their unawareness of a healthy amount of calories to exhaust every day. In order to establish the correct amount, we have to do a bit of work. This is where we get to calories.
First of all, what are calories? A calorie is the energy value of food determined by a nutritionist. Our daily calorie intake must be appropriate for our age, body weight, height, activity and, surprisingly, our climatic zone. Theoretically, a person weighing 55 kg and living in the temperate zone uses an average of 2300 calories per day. This number reckons with an 8 hours work-day and with 8 hours of sleep. Someone who consumes more calories than they can use in a day develops a surplus of nutrients which compromises the healthy balance of their body. Excess nutrients are collected by our bodies as fat tissue and the next step from overweight is obesity – a far-spread problem among today’s pleasure-seeking people.
