5 × age (years) + 5
BMR (women) = 10 × weight (kg) + 6.25 × height (cm)
- 5 × age (years)
- 161
2. Calculate TDEE
Multiply the BMR by an activity factor corresponding to your lifestyle:
Sedentary (little or no exercise)
BMR × 1.2
Lightly active (light exercise/sports 1-3 days a week)
BMR × 1.375
Moderately active (moderate exercise/sports 3-5 days a week)
BMR × 1.55
Very active (hard exercise/sports 6-7 days a week)
Understanding nutrition labels can be quite enlightening, especially when you come across the term “per serving.” This phrase indicates the nutritional values, such as calories and nutrients, that pertain to a single serving size of a food product. To explore a deeper understanding of this concept, you might find it helpful to check out what does per serving mean , which will clarify how this measurement impacts dietary choices and portion control.
