Calories – the explanation can be found here.
Calorie a unit of energy that carries any product. Under the calorie content of food means the amount of energy that is released when it cleavage.
Proteins, fats and carbohydrates – the main sources of energy necessary for vital activity – are expressed in calories: 1 gram of protein and carbohydrates contain 4 calories, 1 gram of fat – 9 calories. Is not difficult to figure out that one kilogram of fat contains approximately 7700 calories.
Armed with this data, as well as handbooks on the nutritional value of food, you can easily find out how many calories in a given product and calculate how many calories you consume over a specific period of time.
Caloric intake of any person must meet the challenges of the day: if you grow thin – it is a diet, if the muscle is increasing – another, if just stick to healthy eating – the third, etc.
How many calories should have a person a day?
The exact number of calories is determined from experience, because it depends on many factors: the style and circumstances of life, level of physical activity, hormone production in the body. By the way, the more human muscle, the higher its basic metabolism.
For people who wants to lose weight, especially after all is the balance of calories. Any weight loss is based on reducing calories. If you ingested more calories than you spend – you get better. If you spend more than you consume, you will inevitably lose weight. The consumption of only 100 extra calories a day will lead to the fact that people get better at 5 kg per year!
How many calories needed to lose weight?
First you need to calculate how many calories needed to maintain your present weight by the following formula: weight (in pounds) x 14 for women, and weight (in pounds) x 15 for men (1 pound = 0.453 kg). The resulting figure will give you the approximate number of calories that you need daily to maintain your weight. And on the same formula, calculate the number of calories for your desired weight and start to follow.
When dieting, avoid very low calorie (less than 1200 calories) for a long period of time. Such a diet will not only reduce the amount of fat, it will reduce the number of your muscles. A strong limiting caloric intake to 45% energy deficit will be obtained from the body is not fat, but from the burning of the body muscles. This will lead to slower metabolism.
A man who seriously enjoys fitness and strives to build muscle or lose weight knows that some workouts a lot to be had – here a 75% success also depends on energy intake and food choice.
