Blood Sugar, Inflammation, and Fertility: What Preconception Health Really Requires
One of the most overlooked factors in preconception health is high blood sugar.
Chronically elevated or unstable blood sugar contributes to inflammation at the cellular level, which directly impacts egg quality, sperm quality, and early embryo development.
How Blood Sugar Impacts Reproductive Health
Here’s the basic physiology:
Carbohydrates break down into glucose
Glucose enters the bloodstream
Insulin moves glucose into cells for energy
Problems arise when this system becomes a rollercoaster, repeated spikes followed by crashes.
Research links dysregulated blood sugar with:
Reduced fertility
Increased pregnancy complications
Poorer embryo outcomes

What Influences Blood Sugar Balance
Blood sugar is affected by:
What you eat
When you eat
How foods are combined
Movement
Stress
Sleep
Hormones
Certain medications
This is why preconception care cannot focus on food alone.
A Practical Target (Without Extremes)
For many people in preconception, a general target of ~15–30% of intake from carbohydrates can support blood sugar balance, but restriction is not the goal.
Research shows that telling people not to eat certain foods often backfires, increasing fixation and intake rather than reducing it.
Instead, a nutrition-by-addition approach is more effective.
Give Carbs a Friend
Rather than “fewer carbs,” teach:
Protein
Fat
Fiber
This slows glucose absorption and stabilizes blood sugar.
Simple tools:
Plate method:
½ plate vegetables (with fat)
¼ protein
¼ carbohydrate
Savory breakfasts instead of sweet-only meals
Pairing sweets with protein, fat, and fiber
Visual tracking works better than calculations:
Photos of meals
No macros required
