Calorie is a unit of energy. We tend to associate calories with food, but they actually apply to anything that contains energy. Most of us associate calories with what we eat or drink, such as "This soda contains 200 calories." In fact, the calories listed on food packaging are kcal, also recorded as a capital letter C, which is equivalent to the heat required to raise 1000 grams of water from 14.5 degrees Celsius to 15.5 degrees Celsius under 1 atmosphere of pressure, which is approximately equivalent to 4186 joules. able. (1000 calories = 1 kcal). So, that can of soda actually contains 200,000 calories (but don't worry, this applies to exercise too - when the exercise chart says you burn 100 calories by jogging 2km, it means 100,000 calories). In English, "calorie" (the first letter is lowercase) means calories, which is approximately equal to 4.186 joules, and "Calorie" (the first letter is capital letters) means calories, which is approximately equal to 4186 joules.

Calories are generally divided into two types:

Kcal, also recorded as a capital letter C, is most commonly seen on food labels and is equivalent to 1,000 grams of water in 1 The heat required to raise the temperature from 14.5°C to 15.5°C under atmospheric pressure is approximately equal to 4186 joules of internal energy.

Small calories, also recorded as cal, are more commonly seen in scientific research documents. 1000 small calories = 1 large calorie (1 Calorie)

Just as computers consume power, trucks consume Oil, daily activities of the human body also consume calories. In addition to providing the energy needed for exercise, daily work and life, calories also provide the energy needed for human life activities, blood circulation, respiration, digestion and absorption, etc. People who lose weight can burn fat through exercise, which can accelerate the consumption of calories to achieve healthy weight loss.

Calories come from carbohydrates, fats, and proteins

Carbohydrates generate heat energy = 4 kcal/g

Protein generates heat energy = 4 kcal/g< /p>

Calories generated from fat = 9 kcal/g.

1. People should know how many calories they should consume every day and how many calories their body needs. It depends on many factors, such as how quickly you want to complete your weight loss plan or how many calories you burn during physical activity. Under normal circumstances, women should not consume less than 1,200 calories per day.

2. Have your own diet plan and execute it perfectly. Of course you can always adjust this, but if it's not necessary, it's best to keep the basic plan. Plan for at least three meals and two snacks. Feeling deprived of food can make losing weight more difficult. Making sure you're getting enough energy from each food group, especially fat and protein, will help keep you feeling full.

3. Correctly track daily calories. There are many ways to track, such as using a form to record it. Remember to keep track of any additional snacks and drinks, including soda and juice. Write down the amount of food and snacks you consume at each meal. Measuring or weighing your food can give you an exact calorie count. You may also consider using a calorie counter. At the end of each day, total caloric intake is calculated. Try to spread the calories you consume evenly throughout the day.
