Blood Sugar, Fertility, and the Missing Link Most Women Overlook

When you think about supporting your fertility, your mind might go to:

• ovulation tracking
• supplements
• hormone testing

But there’s one foundational piece that often gets overlooked:

Your blood sugar stability.

And according to registered dietician Katie Chapmon, this may be one of the biggest factors impacting fertility today.

I sat down with Katie on the Her Fertility Podcast to breakdown the science behind fertility nutrition and how to actually support your fertility through diet. 

LISTEN TO THE PODCAST

Why Blood Sugar Matters for Fertility

Every time you eat, your blood sugar rises and falls.

That’s normal.

But what we don’t want is a rollercoaster.

Instead, we want what Katie calls a “lazy river.”

A gentle rise.
A steady flow.
A gradual fall.

Because when blood sugar becomes unstable:

• insulin spikes
• cortisol increases
• reproductive hormones are impacted

And all of these hormones are connected.

Think of your hormones like a symphony, each one plays a role, but they have to work together to create harmony.

When one is off, the whole system feels it.

The Hidden Stressor in Your Fertility Journey

If you’ve been focusing on your nervous system (like we talk about often), here’s something important to understand:

Food can also be a stressor.

Not just what you eat, but:

• when you eat
• how often you eat
• how consistent your rhythm is

Your body thrives on predictability and safety.

And when your eating patterns are inconsistent, your body can interpret that as stress.

The Biggest Nutrition Pattern Affecting Fertility Right Now

One of the most common patterns Katie sees across both men and women in 2026 is:

Blood sugar dysregulation.

This can look like:

• skipping meals
• long gaps between eating
• inconsistent meal timing
• relying on quick carbs without support

Over time, this creates instability in the body — and fertility is highly sensitive to that instability.

Should You Be Fasting for Fertility?

This is where things get really important.

Intermittent fasting is often promoted as a way to “balance hormones.”

But for women trying to conceive, especially:

Fasting in the morning can actually work against you.

Why? Because it can:

• spike cortisol
• disrupt blood sugar early in the day
• signal stress to the body

Instead, Katie recommends:

Eating within 60–90 minutes of waking

This helps:

• stabilize blood sugar
• support hormone production
• create a sense of safety in the body

The Better Way to “Fast” for Hormone Support

If fasting is used at all, it’s more supportive at the end of the day, not the beginning.

This looks like:

• stopping food a few hours before bed
• allowing your body to rest overnight

Why this works:

• improves sleep quality
• supports overnight hormone regulation
• reduces digestive strain

3 Simple Ways to Support Your Fertility Through Nutrition

You don’t need a complicated plan to start seeing shifts.

Here are three foundational practices you can implement right away:

1. Eat Consistently

Aim to eat every 3–5 hours.

This creates a rhythm your body can trust.

Example:

• breakfast
• lunch
• snack
• dinner

Consistency is more powerful than perfection.

2. Build Colorful Plates

A simple rule:

Aim for 3–5 different colors on your plate.

Why? Because color = antioxidants
And antioxidants support egg and sperm quality

Think:

• greens
• reds
• oranges
• purples

The brighter, the better.

3. Never Eat Carbs Alone

Carbohydrates are not the enemy, they’re essential for fertility.

But they need support.

Always pair carbs with:

• protein
• healthy fat

Katie says it best: “Fruit needs a friend.”

Examples:

• apple + nut butter
• toast + eggs
• rice + fish

This helps stabilize blood sugar and prevent spikes.

What About Weight Loss and Fertility?

This is a nuanced conversation.

Yes, weight can impact fertility in some cases.

But how you approach weight loss matters deeply.

Extreme approaches:

• restrictive dieting
• over-exercising
• fasting

…can actually signal stress to the body and work against fertility.

Instead, the focus should be on:

• nutrient sufficiency
• consistent patterns
• long-term sustainability

Because your body needs to feel: safe enough to support life

Fertility Nutrition Is Not One-Size-Fits-All

One of the biggest misconceptions is that there is a “perfect fertility diet.”

But the truth is:

Nutrition must match your body and your goals.

What works for:

• weight loss
• athletic performance
• general health

…may not be what supports fertility.

This is why individualized support can be so powerful — it helps you identify:

• gaps
• patterns
• opportunities for support

that you might not see on your own.

The Bigger Picture: Stability = Safety

Whether we’re talking about:

• your nervous system
• your hormones
• your nutrition

The goal is the same:

Create stability

Because when your body feels stable, it feels safe.

And when your body feels safe…

It can prioritize fertility.

You Don’t Have to Figure This Out Alone

If you’ve been trying to piece everything together: nutrition, hormones, timing, and still feel like something is missing…

You’re not doing anything wrong.

You may just need a more personalized, whole-body approach.
