Fueling Your Return to Training Postpartum: What Every Mama Needs to Know

Returning to training postpartum can feel both exciting and overwhelming. Your body has just gone through one of the most metabolically demanding experiences of your life, and even though you may be eager to get moving again, the foundation of a strong comeback starts with how you fuel. Whether you’re a few weeks or a few months postpartum, the nutrition choices you make now have a huge impact on healing, energy, performance, and - most importantly - how good you feel day to day.

Here’s what every postpartum mama should keep in mind when stepping back into training.

1. Ease Back In - Your Body Is Still Healing

Even if you feel mentally ready to crush your old workouts, physiologically your body is still in recovery mode for many months after birth. Your core and pelvic floor tissues are healing, hormones are shifting, and your energy demands are higher than usual.

And here’s the key: training is a stressor. Healing is also a stressor.

Your nutrition is what helps your body handle both.

Start with gradual, intentional reintroduction of movement - walking, breath work, core and pelvic floor rehab - and pair it with enough energy (food) to support tissue repair. Underfueling during this time can slow healing, worsen fatigue, and lead to setbacks in training.

There is no “bouncing back.” There is rebuilding - and that takes intentional nourishment.

2. Eating Enough: Your Body’s Top Priority

Postpartum moms often underestimate just how much energy they need. Between healing, disrupted sleep, training, and potentially breastfeeding, your calorie requirements are higher than pre-pregnancy.

Breastfeeding alone increases daily energy needs by roughly 300–500 calories. Add training and recovery on top of that, and you’re looking at a significantly increased demand for energy. Without proper nourishment, our body is at higher risk of injury and illness.

What to watch out for:

• fatigue

• "hitting a wall" in your workouts or midday

• ravenous hunger

• light-headedness

• frequent illness

• injury

• increased irritability

• difficulty seeing improvements in sport performance

  
  

One of the difficult pieces to this puzzle in postpartum is that many of these symptoms come with the territory of caring for a newborn - hello sleepless nights! What's important is that you are mindful about what your body could be telling you. And if you are noticing many of these symptoms, consider if you are eating enough to fuel your body for all its functions.

3. Snack Smart & Snack Often

Your hunger cues postpartum can be unpredictable - especially if you’re breastfeeding. Quick, balanced snacks can bridge the gaps and help you meet your energy needs without feeling overwhelmed.

Think carbs + protein:

• Apple + peanut butter

• Greek yogurt + granola

• Hummus + crackers

• Trail mix

• Cottage cheese + fruit

• Cheese + whole grain toast

Small, consistent snacks stabilize blood sugar, sustain energy levels, and help you reach your higher energy requirements.

4. Hydration Needs Are Higher Than You Think

Hydration plays a huge role in energy levels, milk supply (if breastfeeding), and overall recovery. Birth, blood loss, and breastfeeding all increase fluid requirements.

Aim for: 2–3+ litres per day, more if breastfeeding or training intensely.

Consider adding electrolytes, especially on days you sweat more or struggle to stay hydrated.

5. Prioritize Recovery Nutrition - It Matters More Than Ever

Postpartum training isn’t just about the workout - it’s about how well you recover from it.

A balanced post-workout meal/snack (ideally within 30–60 minutes) helps:

• Rebuild muscle

• Support tissue healing

• Reduce soreness

• Improve energy for the rest of the day

• Prevent nighttime hunger

• 
  

Aim for carbs to refuel + 20–30g protein to repair.

Examples:

• Smoothie with fruit + Greek yogurt or protein

• Turkey sandwich

• Oatmeal with nut butter + protein

• Eggs + toast + fruit

6. Caffeine Is Not a Meal (Sorry, Mama)

Coffee is a lifeline in the newborn stage, but it can’t replace real fuel. Many postpartum moms unintentionally rely on coffee to get through the day, only to feel shaky, irritable, or depleted later.

Use caffeine strategically and pair it with food. Keep total intake throughout the day to ;ess than 300mg (2-3 cups/day). Your nervous system (and tummy) will thank you.

7. Sleep + Nutrition = Your Power Combo

Postpartum sleep is… unpredictable. And when sleep is low, your body craves more energy.

This is normal.

Lack of sleep increases hunger hormones, decreases satiety, and makes quick carbs even more tempting. Instead of fighting it, plan for it:

• Add extra snacks

• Increase carbs at meals

• Don’t train fasted

• Give yourself grace

Training on an underfueled, poorly rested body increases injury risk and slows progress. Supporting your nutrition helps buffer the impact.

Lots of recovery happens overnight. Consider enjoying a nighttime snack containing a caseine-rich food (yogurt, cheese, milk) as research suggests this type of protein is more optimal for overnight recovery! Bonus, by having a snack before bed, you prevent waking due to hunger overnight, allowing you to have a more restful sleep (until the baby wakes up that is!).

The Bottom Line

Postpartum training is less about intensity and more about strategy.Fuel consistently. Increase movement gradually. Rest intentionally.

You don’t need to earn your food - and you don’t need to “bounce back”. You’re rebuilding strength for a new season of life, and the right nutrition will carry you there.
