The heat that everyone needs to maintain life every day, such as breathing and heartbeat, is called basic heat.
The basic calorie of women aged 40-50 is about 1300~ 1500. It's all about height.
Of course, people can't be completely inactive, so more than just basic heat is enough.
The average person's activity coefficient is different, and the higher the activity, the higher the value.
Labor intensity male activity coefficient female activity coefficient
Mild 1.55 1.56
Medium 1.78 1.64
Severity 2. 10 1.82
Daily calories required to maintain current weight:
Women aged 30-59:
(8.7× body weight kg +829 )× activity coefficient
For example: 35 years old, light manual labor, weighing 50 kilograms, daily intake of calories to maintain the current weight:
(8.7× 50+829 )×1.56 =1971card
To lose weight, the calorie intake should be lower than 197 1 calorie.
