In science, calories represent a unit of energy. It is equal to the force required for one liter of water to be heated to a degree. What we call a calorie diet are actually kilocalories.
A one kilocalories contains 1,000 calories. Nutritional use this unit for the amount of energy which is in the foods that we consume. But, what you should know about calories?
1. How many calories we need per day?
The number of calories that we need during the day depends on age, body shape and how active you are during the day. The majority of teens and adults need between 1,500 and 2,500 calories per day. The more weight you have, the more calories you need to maintain weight.
2. How calories affect weight loss?
Half a kilogram of fat is equal to 3,500 calories. So, to lose weight about half a kilogram, you should burn 3500 calories with exercise, or reduce their imports. And to lose half a kilo a week, is required on a daily basis to reduce the intake of calories by 500th.
3. How much physical activity influences the calories?
Any physical activity requires energy, so increased activity with the same calorie intake throughout the day will increase their consumption as well. Also with a workout that builds muscle mass increases your metabolism, which means that the body needs more calories – even when you do not exercise much. Building muscle is a good way to achieve a healthy body weight.
4. What is the best way to track how many calories we entered?
For example, the simplest way is to write on a piece of paper how much you entered in during the day, or to keep some sort of a food diary. But there are numerous websites that offer you the opportunity to track how many calories you entered, such as Calorie Count.
5. Not all calories are the same. But what does that mean?
All calories are equal in energy terms. Each gram of carbohydrate has four calories, every gram of protein has four calories, and every gram of fat has nine. That doesn’t change. The term all calories aren’t equal means that some sources of calories are better than others. So, instead of 250 calories of chocolate, it would be better to do a combination with 250 calories from several different sources, such as bananas, apples and pears.
