What Postpartum Hormones Are Actually Doing to Your Body.

And Why the Answer Is Not to Fight Them — It’s to Outsmart Them.

By Coach Mini  |  Certified Personal Trainer & Nutritionist  |  Founder, Riv Method

One of the first things I tell every postpartum client who comes to me frustrated is this:

There are things we can control, and things we cannot. Hormones sit somewhere in the middle. You cannot control them completely — but with time, the right nutrition, and a consistent routine, you can make them manageable. And manageable is enough to make real progress.

This post is going to help you understand what is actually happening in your body — without the science overload — and more importantly, what to DO about it.

Because the goal is not to obsess over your hormones. The goal is to get so focused on what you CAN control that your hormones become background noise.

The 3 Hormones Every Postpartum Mom Needs to Know

1. Estrogen — The Mood and Metabolism Hormone

After birth, estrogen drops significantly. This affects your mood, your energy, your libido, and yes — your ability to lose fat. Low estrogen makes fat storage easier and fat loss harder. It also contributes to the emotional rollercoaster many moms feel in the early postpartum period.

2. Cortisol — The Stress Hormone

Sleep deprivation, newborn stress, and postpartum recovery all raise cortisol. High cortisol increases hunger, drives cravings for sugar and carbs, and signals the body to store fat — especially around the belly. This is why moms who are exhausted and stressed find fat loss so much harder. It is not a willpower issue. It is biology.

3. Prolactin — The Breastfeeding Hormone

If you are breastfeeding, prolactin is elevated — and it actively suppresses estrogen. This is why breastfeeding moms often experience slower fat loss. Prolactin tells the body to hold onto fat reserves to protect milk supply. It is not your fault. It is your body doing its job.

The 80/90% Rule — Coach Mini’s Approach

Here is the honest truth about postpartum hormones: you can manage about 80–90% of their effect through your lifestyle. The remaining 10–20%? Accept it. Work around it. Don’t let it derail you.

What does managing 80–90% look like?

→  Mood swings from low estrogen: You cannot stop them completely. But consistent protein intake, regular movement, and adequate sleep reduce their intensity significantly.

→  Cravings from high cortisol: You cannot eliminate cravings. But you can manage them. If you are craving something — eat it after a meal, eat less of it, and don’t make it the whole day. One indulgence does not ruin your progress.

→  Fat storage from prolactin: You cannot override this completely while breastfeeding. But a small calorie deficit and high protein intake will still produce results — just slower ones. And slower is fine.

The Real Strategy — Get So Busy Doing the Right Things That Hormones Become Background Noise

This is the philosophy I live by and coach by:

Get so focused on your nutrition, your movement, your sleep, and your routine that your hormones stop being the centre of your attention. Because there is nothing you can do about them anyway — so stop giving them that power.

When you are eating enough protein, moving daily, sleeping as much as possible, and staying consistent with your plan — your hormones start working with you instead of against you. Not because you fixed them. But because you built a lifestyle strong enough to carry you through them.

Aim for 90% on plan. The other 10% — give yourself grace. That is not failure. That is being human.

What to Do This Week

Don’t try to fix your hormones. Do these instead:

→  Eat protein at every meal. This stabilises blood sugar, reduces cortisol-driven cravings, and protects muscle.

→  Move for 10–20 minutes daily. Even a walk. Movement reduces cortisol and improves estrogen sensitivity over time.

→  Sleep as much as you possibly can. Every extra hour of sleep reduces cortisol and helps hormone regulation.

→  Don’t restrict aggressively. Extreme calorie cuts spike cortisol and make everything worse. Small, sustainable deficit only.

→  When you crave something — manage it, don’t eliminate it. Eat it after a meal. Eat less of it. Move on.
