Why meals make you tired
Large carb-heavy meals with little protein, eaten quickly, drive a big insulin response and trigger sleepiness via serotonin pathways.
Fixes
Protein first, vegetables second, carbs last. Walk 10 minutes after eating. Cap meal size. These three changes eliminate most post-meal crashes.
Frequently asked questions
- Is post-meal fatigue a diabetes sign?
- Sometimes — persistent reactive hypoglycemia warrants a glucose tolerance test.
- Does a small dessert help?
- Rarely. Sugar usually amplifies the crash 90 minutes later.
