Generally 1500~2000 calories should be enough, it varies from person to person.

The standard of calorie intake during weight loss should be assessed by a combination of factors such as age, gender, current weight, and target weight. In general:

Men of the same weight have a greater calorie demand than women;

Adults of the same weight have a greater calorie demand than minors and the elderly;

It is also related to other factors, such as engaging in different occupations, the daily consumption is also different; physical labor is more than the consumption of mental labor.

There are many other factors that influence the difference in calorie needs. It is recommended that you download the Mint App or other fitness apps for a detailed assessment, which will give you the recommended amount of calories.

Expanded Information:

Calories, a measure of the amount of energy consumed by a person. p>Calorie, a unit of energy. We tend to associate calories with food, but they actually apply to any substance that contains energy.

Simply put, one calorie of energy or heat raises the temperature of one gram of water at one atmosphere by one degree C. One calorie is equal to about 4.186 joules (a joule is a unit of energy commonly used in physics).

Most of us associate calories with what we eat or drink, as in, "This soda has 200 calories. In reality, the calories listed on food packages are large calories, also noted with a capital C. They are equivalent to the amount of heat required to raise 1,000 grams of water from 14.5 degrees Celsius to 15.5 degrees Celsius at 1 atmosphere of pressure, which is equivalent to about 4,186 joules of internal energy. (1000 calories = 1 calorie).

So, in reality, this listening soda contains 200,000 calories (but don't worry, this applies to workouts as well - when the exercise chart says you burn 100 calories jogging 2 kilometers, it means 100,000 calories). In English, "calorie" (initial lowercase) means calorie, which equals about 4.186 joules, and "Calorie" (initial capital) means large calorie, which equals about 4,186 joules.

There are two other types of calories commonly referred to:

The large calorie, also noted with a capital C, is most commonly used in food labeling, and is equivalent to the amount of heat required to raise 1,000 grams of water from 14.5 to 15.5 degrees Celsius at 1 atmosphere, which is equal to about 4,186 joules of internal energy.

Small calories, also noted as cal, are more commonly found in scientific research documents, where 1,000 small calories = 1 large calorie (1 Calorie)
