Kilocalories are calories. Some books are expressed by KJ, which means kilojoule. 1kcal=4. 184KJ .
If you want to calculate your daily calorie demand, you must first know your height, weight and labor intensity.
White-collar workers, salespeople and teachers are all light manual workers. A person with extremely light physical strength refers to a person who is ill in bed.
Students, drivers, surgeons, and electricians belong to medium manual workers. Because they use more brains, they should be highly concentrated.
Farmers, porters, construction workers and dancers are all heavy manual workers.
1. Use your height (cm)- 105 = your standard weight (kg).
2. Your actual weight (kg)/ height (m? ) = Body Mass Index (a measure of your figure)? 18.5~23.9 is normal, < 18.5 is emaciation, 24~28.9 is overweight, and > 29 is obesity. Different body mass index values require different calories. Give you a list:
3. Energy required per day = standard weight (note) × energy required per kilojoule weight (this is the above table).
Let me give you an example.
For example, a girl 1.65m has an actual weight of 50kg. Is a high school student.
Then: her standard weight = height (cm)-105 =165 cm-105 = 60 kg.
? Her body mass index = actual weight (kg)/ height (m? )=50kg/ 1.65(m？ )= 50k g/( 1.65m× 1.65m)= 18.3
? From what I said above, 18.5 belongs to emaciation. And because he is a high school student, he belongs to manual workers. Looking up the table, we can see that her calorie requirement per kilogram of body weight is 45 kilocalories.
? The calories she needs every day = standard weight ×45kcal=60kg×45kcal=2700kcal.
It's easy to get confused, sometimes with actual weight, sometimes with standard weight. I can also help you calculate your height, weight and occupation. Typing is hard ~ adopt it!
