About Us – MyCalorieDeficit

Our mission

To take the guesswork out of weight-loss math. We turn proven formulas into fast, friendly tools so you can set realistic targets—and stick to them.

What you can do here

  • Calorie Deficit Calculator: Find a daily calorie target tailored to your goal.
  • TDEE Calculator: Estimate total calories you burn per day.
  • BMR Calculator: See your baseline (resting) energy needs.
  • Macro Calculator: Split calories into protein, carbs, and fats.

How about our calculators working

We use widely accepted equations and activity multipliers to keep results consistent and comparable:

  • Mifflin–St Jeor and Harris–Benedict for BMR estimates.
  • Katch–McArdle option when body-fat % is known (lean-mass BMR).
  • Activity factors to move from BMR → TDEE.
  • Sensible deficit ranges (typically –300 to –500 kcal/day) for gradual, sustainable change.

We cite sources in our guides and periodically review inputs, rounding rules, and defaults to reflect current best practices.

Editorial standards

  • Evidence first: We reference primary research and reputable public-health sources.
  • Plain language: Jargon-free explanations and examples you can apply today.
  • Review cadence: Tools and articles are revisited on a rolling schedule to keep them accurate and helpful.
  • Corrections welcome: If you spot an error, tell us—see the Contact page.
