Diet Heart Rate Calculator

Calculate target heart rate zones for weight-loss training. Use age, resting heart rate, weight, and weekly cardio time to estimate fat-burn zones, cardio intensity, calories per hour, and whether your training intensity fits your diet goal.

How to use this calculator

  • Enter age and resting heart rate.
  • Add body weight and weekly cardio minutes.
  • Use the fat-burn zone for steady cardio and the cardio zone for higher intensity work.

What the result means

The output uses heart rate reserve to show a sustainable fat-burning zone and a harder cardio zone. The score improves when weekly cardio and resting heart rate support consistent training.

Max HR = 220 − age. HRR = Max HR − resting HR. Target HR = resting HR + HRR × intensity.

Heart rate zones are estimates. Stop exercise if you feel chest pain, dizziness, or abnormal symptoms, and follow medical advice when applicable.

Example calculation

For age 35 and resting heart rate 65 bpm, estimated max heart rate is 185 bpm and fat-burn training is roughly 125–143 bpm.

Tips for better results

  • Use Zone 2 cardio for sustainable dieting phases.
  • Combine heart-rate training with calories and steps.
  • Track resting heart rate trends over time.

FAQ

What heart rate burns the most fat?

Moderate intensity often supports fat oxidation, but total calorie balance still determines weight loss.

Is fat-burning heart rate real?

Fat-burning zones are useful for intensity control, but they do not override total energy balance.

Should I stay in Zone 2 to lose weight?

Zone 2 can help consistency and recovery, especially when dieting, but some higher intensity work can also be useful.

What is the best heart rate for cardio?

The best cardio range depends on your age, resting heart rate, fitness level, and training goal.

How do I calculate my target heart rate?

This calculator uses the heart rate reserve method: resting HR plus a percentage of the difference between max and resting HR.
