Postpartum Calorie Deficit Calculator

A postpartum calorie deficit calculator helps you understand how many calories you can safely reduce each day if you want to lose weight after giving birth. It takes into account your current needs and suggests a gentle deficit that supports your recovery and milk supply if you are breastfeeding.

Many new moms want to lose pregnancy weight but worry about eating too little. This tool gives you a safe and realistic calorie target so you can focus on feeling healthy rather than rushing results.

Why This Matters

After giving birth, your body needs time to heal. Rapid weight loss can affect your energy, milk supply, and overall well-being. This calculator helps you create a gentle calorie deficit that respects what your body is going through during the postpartum period.

It is designed to support you in making informed choices while prioritizing your health and your baby's needs.

How This Calculator Works

This calculator first estimates your total daily calorie needs (TDEE) based on your age, weight, height, activity level, and breastfeeding status. It then creates a safe deficit based on your chosen weight loss goal. The result is a daily calorie target that aims to be sustainable and respectful of your recovery.

How to Use This Calculator

1. Enter your age, current weight, and height.
2. Select your activity level.
3. Choose your breastfeeding status.
4. Select your weight loss goal (maintain, slow loss, or moderate loss).
5. Click "Calculate" to see your recommended daily calorie target.

Worked Example

If you are 30 years old, weigh 68 kg, are 165 cm tall, moderately active, exclusively breastfeeding, and want slow weight loss:

• Your estimated daily calorie needs: ~2,710 calories
• Safe deficit for slow loss: -250 calories
• Your daily calorie target: ~2,460 calories

This is a gentle and realistic target for gradual weight loss while supporting your recovery and milk supply.
