If you feel wired, shaky, or on edge like clockwork most days, it’s worth looking at what’s happening to your blood sugar before you assume it’s purely psychological.
When blood glucose drops too fast, your body treats it as a threat. It releases adrenaline and cortisol to push glucose back up. Those are the same hormones involved in a stress response, which is why a glucose crash and an anxiety spike can feel identical: racing heart, shaky hands, a sense of dread, trouble concentrating.
This doesn’t mean all anxiety is a blood sugar problem. Anxiety is complex, and psychological, situational, and neurological factors matter too. But if your “anxiety” shows up reliably a few hours after a carb-heavy, protein-light meal, or after skipping lunch, or after your third coffee on an empty stomach, that’s not a coincidence.
Five things that will help:
→ Anchor meals with protein, not just carbs. Aim for 30g+ at breakfast, this is where most people underdo it.
→ Don’t skip meals when you’re already stressed. Undereating raises stress hormones on its own. Add a glucose dip and you’ve stacked two triggers.
→ Never eat carbs alone. Pair them with protein, fat, or fibre to slow the release and flatten the crash.
→ Watch caffeine on an empty stomach. It raises stress hormones by itself, which is fine unless it isn’t. Combined with low blood sugar, you get a physiological anxiety response with no obvious cause.
→ Walk after you eat, not instead of eating. It helps glucose move into muscle and blunts both the spike and the crash.
