Common Mistakes to Avoid With the BMR Calculator (Lean Body Mass)
Most people who stumble with a calculator make the same handful of slips. None are hard to avoid once you know them:

- Leaving a field empty: a missing value simply stops the math. Fill every required field and the tool takes it from there.
- Rushing the result: the answer appears fast, so it is tempting to grab it and go. A one-second read of the figure prevents the classic wrong-number blunder.
- Remembering an old formula: formulas shift with context — age, units, or assumptions. Let the tool apply the version that matches your situation instead of trusting a memory.
- Entering values that do not fit the question: the tool can only work with what you give it. If the result looks odd, check whether the numbers you typed actually match what you meant to ask.
