In science, calories represent a measure unit for energy. It is equal to the power required for one liter of water to be heated for one degree.
What we call a calorie diet are actually kilo-calories. One kilo-calorie contains 1,000 calories. We use this unit to see the amount of energy which is situated in the food we consume.
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 many 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 about 3,500 calories when exercising or reduce their intake. And to lose half a kilo a week is required to reduce the intake of calories by 500 on a daily basis.
3. How much physical activity influences the calories?
Any physical activity requires energy, so increased activity with the same calorie intake throughout the day and will increase their consumption. Also, strength training 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 monitor how many calories are consumed?
You can write on a piece of paper how you consumed during the day or to keep some sort of food diary. There are numerous websites that offer you the opportunity to track how many calories you have consumed, 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, each gram of fat has nine. It does not change.
The term “all calories are not equal” means that some sources of calories are better than others. Instead of 250 calories of chocolate, it would be better to do a combined 250 calories from several different sources, such as bananas, apples and pears.
