AI Overview Summary

Feeling tired after eating carbohydrates after 40 may be influenced by carbohydrate quality, portion size, low protein or fiber, poor sleep, stress, dehydration, long sitting, hormone changes, or reduced insulin sensitivity.

The best first step is usually not eliminating all carbohydrates. Combine a moderate whole-food carbohydrate portion with protein, vegetables, healthy fat, water, and a short walk when medically appropriate.
