Method one. Simple algorithm: (unit card)
Female: Basic Calories = Weight (kg) x9
Male: basal calories (calories) = body weight (kg) x 10.
Method 2, accurate algorithm: (unit card)
1, accurate calculation method for women
18-30 years old 14.6x weight (kg) +450
3 1-60 years old, 8.6x weight (kg) +830
Over 60 years old, 10.4 times body weight (kg) +600
2. Accurate calculation method for men
18-30 years old 15.2 times body weight (kg) +680
3 1-60 years old 1 1.5x body weight (kg) +830
Over 60 years old, 13.4 times body weight (kg) +490
Extended data:
There are three sources of heat in food:
There are three kinds of calories in food: protein's calories are the basic nutrients to strengthen muscles, mainly from meat, dairy products and eggs, with 4 calories per gram; Carbohydrate calories are the main energy source of human body under normal circumstances, which are contained in rice, flour, noodles, bread, cereals, vegetables and fruits, and each gram of calories is also 4 calories; Fat contains 9 calories per gram, which is found in both oil and cream.
There is also a kind of heat called "deficiency heat", which refers to those foods that only provide energy but have low nutritional value, such as cold drinks, alcohol and fast food.
The ideal calorie ratio of each meal is probably: carbohydrate 65%, fat 20%, protein 15%.
