If the fields weren’t necessary, we wouldn’t ask you to fill them.

If you are confused about the Activity section in our BMR Calculator for Weight Gain, this is how it works:

No Activity – if you are not active, you should check this radio button.

Less Activity – if you exercise sometimes (once or twice a week), check this radio button.

Moderate Activity – if you exercise often and are active, check this radio button.

Good Activity – if you exercise daily and are active, check this radio button.

Activity levels in our BMR Calculator for Weight Gain are important because they make the required calories differ from person to person.

We have separate tools related to Basal Metabolic Rate (BMR) for different purposes as well like BMR Calculator for Women, BMR Calculator for Weight Loss, BMR Calculator for Men, and BMR Calculator.
