Calories

What is calorie? In scientific terms, it is the energy needed to raise the temperature1 gram of water through 1 Celsius. That's not much help. In other words, calories are like fuel. Without calories, our cells would die and then eventually we would die.

Food breaks down into 3 main macronutrients:

1.  Carbohydrates (carbs)
2. Proteins
3. Fats

1 gram of protein = 4 calories
1 gram carbs = 4 calories
1 gram fat = 9 calories

This doesn't mean we should go dive into fats. The calories our bodies don't use will turn into stored energy, or as you may know it as fat in your body. We need to eat as many calories as our body burns. If you eat 2500 calories that day, you will need to burn 2500 calories that day so your body doesn't store too much fat.

 

You may of also heard of empty calories. Empty calories have no nutrition, so therefore they have no energy in them. Sugar, for an example, is an empty calorie because it has no nutrition. It may boost you for 10 sec. but in the long run, you wont have any more energy.

 

Have a basic idea?
