Why Healthy Fats Matter for Hormones (And Why Most Women Need More of Them, Not Less)
For decades, women have been taught to fear fat.
Low-fat yogurt.
Fat-free salad dressing.
Skip the egg yolks.
Avoid avocados.
Choose the "light" version.
Somewhere along the way, fat became the villain.
Yet in my practice as a Registered Holistic Nutritionist, one of the most common things I see in women struggling with fatigue, cravings, mood swings, stubborn weight gain, poor sleep, brain fog, irregular cycles, and hormone symptoms is not that they're eating too much fat...
It's that they're often not eating enough of the right kinds.
The problem usually isn't healthy fats themselves.
The problem is understanding:
how much your body actually needs
which fats support health and which don't
how to pair them with other nutrients
and how to use them strategically throughout the day
Because when it comes to hormones, healthy fats are not optional.
They're foundational.
First Things First: What Is a Macronutrient?
Before we talk about fats specifically, let's quickly talk about macronutrients.
The word macro simply means "large."
Macronutrients are the nutrients your body needs in large amounts to function properly and produce energy.
There are three macronutrients:
1. Protein
Your body's building material.
Protein helps build muscle, repair tissues, support your immune system, stabilize blood sugar, and produce neurotransmitters that affect mood and focus.
2. Carbohydrates
Your body's preferred energy source.
Carbohydrates fuel your brain, muscles, workouts, hormones, and nervous system.
3. Fat
Your body's long-lasting fuel source and hormone helper.
Healthy fats support everything from brain health and nutrient absorption to cell membranes and hormone production.
None of these are "bad."
Your body needs all three.
Think of them like the legs of a stool.
Remove one leg and the entire system becomes unstable.
So What Exactly Are Healthy Fats?
Healthy fats are primarily:
Monounsaturated fats
Polyunsaturated fats (including Omega-3 fats)
These are the fats that support hormone production, brain health, heart health, blood sugar regulation, and inflammation management.
Examples include:
🥑 Avocados
🫒 Olive oil
🥜 Nuts and nut butters
🌰 Seeds such as chia, flax, hemp, pumpkin, and sunflower
🐟 Fatty fish like salmon, sardines, and trout
🥚 Egg yolks
🫒 Olives
🥥 Coconut products in moderation
These fats provide your body with essential fatty acids that it cannot make on its own and therefore must obtain through food.
Why Do Hormones Need Fat?
Here's the simplest explanation:
Hormones are your body's chemical messengers.
They tell your body when to sleep, when to wake up, when to burn energy, when to feel hungry, when to feel full, and how to regulate mood, metabolism, fertility, stress, and reproduction.
Many of these hormones are built using cholesterol and dietary fats as raw materials. Dietary fat also plays an important role in hormone production and function throughout the body.
Imagine trying to build a house without bricks.
That's essentially what your body is trying to do when it's expected to produce hormones without enough healthy fats available.
Healthy Fats Are About Much More Than Hormones
Healthy fats help:
absorb vitamins A, D, E, and K
support brain function and memory
maintain healthy cell membranes
protect organs
regulate inflammation
support skin health
improve satiety and fullness after meals
stabilize blood sugar
reduce cravings between meals
Without enough dietary fat, your body struggles to absorb fat-soluble nutrients effectively.
A Salad Is a Perfect Example
Imagine eating:
spinach
carrots
peppers
cucumber
Sounds healthy, right?
But if that salad contains no fat at all, your body may struggle to absorb many of the nutrients it contains.
Add:
olive oil
avocado
pumpkin seeds
feta cheese
salmon
Suddenly that meal becomes far more nourishing and satisfying.
The healthy fats act almost like a "delivery vehicle" helping certain nutrients get where they need to go.
Why Many Women Accidentally Under-Eat Fat
Many women are doing things like:
choosing fat-free yogurt
avoiding egg yolks
eating dry salads
skipping nuts because they're "high calorie"
avoiding avocado because they're trying to lose weight
Then they wonder why they're:
hungry an hour later
craving sugar at night
struggling with energy crashes
constantly thinking about food
Fat slows digestion and increases satisfaction after meals, helping regulate hunger and fullness signals.
The Goal Is Balance, Not "More Fat"
This is where many people get confused.
Healthy fats are important.
That does not mean adding coconut oil to everything and eating handfuls of nuts all day.
Like most things in nutrition, more is not always better.
The goal is balance.
Think of healthy fats as supporting actors rather than the main character.
A Simple Formula That Works
At meals, aim for:
✅ Protein
✅ Fibre-rich carbohydrates
✅ Healthy fats
✅ Colourful produce
For example:
Breakfast
Greek yogurt + berries + chia seeds + walnuts
Lunch
Chicken salad with avocado and olive oil dressing
Snack
Apple with natural peanut butter
Dinner
Salmon with roasted vegetables and quinoa
Each meal contains all three macronutrients working together.
That combination often leads to:
better energy
improved fullness
fewer cravings
more stable blood sugar
better support for hormones
Easy Ways to Add Healthy Fats:
If you're unsure where to start:
Add hemp hearts to smoothies.
Put chia or flax into oatmeal or yogurt.
Use olive oil-based dressings.
Add avocado to sandwiches or salads.
Include nuts or seeds with snacks.
Eat fatty fish twice weekly if possible.
Stop throwing away your egg yolks.
Simple changes add up quickly.
The Bottom Line:
Healthy fats do not make women unhealthy.
Healthy fats do not automatically lead to weight gain.
Healthy fats are not the enemy.
For many women, the bigger issue is not eating too much fat.
It's not eating enough of the right fats, at the right times, paired with the right foods.
Your hormones are trying to send messages every single day.
Energy.
Mood.
Sleep.
Cravings.
Cycles.
Focus.
Metabolism.
Healthy fats help make sure those messages get delivered.
And that is something worth nourishing.
