For maintenance calories-
People often ask, How much calories in a day should I consume if I want to maintain my current weight?
For Women, the weight of the woman is 38 kg and the age is 21 years-
BMR = 655 + (9.6 x weight in kg) + (1.8 x height in cm) – (4.7 x age in years) You can also look for an online BMR Calculator.
For Men, if the weight of the man is 45 kg and the age is 25 years-
BMR = 66 + (13.7 x weight in kg) + (5 x height in cm) – (6.8 x age in years)
After calculating the BMR, multiply it by an activity factor:
- Sedentary (little or no exercise): BMR x 1.2
- Lightly active (light exercise or sports 1-3 days/week): BMR x 1.375
- Moderately active (moderate exercise or sports 3-5 days/week): BMR x 1.55
- Very active (hard exercise or sports 6-7 days a week): BMR x 1.725
- Super active (very hard exercise or physical job & exercise 2x/day): BMR x 1.9
