Fasting numbers can be one of the hardest parts of gestational diabetes because they’re strongly influenced by pregnancy hormones and overnight insulin resistance. That means there’s only so much you can control with food and routine — and a “high” fasting number doesn’t mean you failed.



Strategies that may help:
- Check that you’re not fasting too long overnight — for many people, going much longer than 8–10 hours can backfire (follow your clinic’s guidance).
- Experiment with a bedtime snack. Tolerance varies a lot, so there’s no one “best” snack for everyone.
Examples (general ideas):
1. Greek yogurt + berries + a few nuts/seeds
2. Whole-grain toast or crackers + peanut/almond butter (or cheese)
3. Apple/pear + nut butter, or a small handful of nuts + a few berries

Avoid changing multiple variables at once; test one tweak for 2–3 nights to spot patterns.

- Consider adding evening movement (if approved by your provider) and prioritize sleep when possible.
- If fasting is consistently above target, bring logs to your provider—sometimes medication or additional support is needed.
