FAQ
Common questions about this topic
What is BMI?
BMI stands for body mass index. It uses height and weight to place someone into broad statistical categories.
Is BMI accurate for everyone?
No. BMI can be less informative for very muscular people and does not directly measure body fat or health status.
Should I use BMI to set calories?
Not by itself. BMI can provide context, but calorie targets are better set with TDEE, body weight trends, and the user's goal.
