A study in the American Journal of Clinical Nutrition revealed that high consumption of added starches, sugars, and refined grains was associated with a greater risk of sleep deprivation in postmenopausal women.

Of course, not all carbs are equal, and natural, unprocessed carbs don’t have the same glycemic load on the body. Even so, healthier carbs like sweet potatoes and beans also impact your blood sugar, and eating too many of them could also leave you feeling a little tired.
Food allergies have also been shown to promote post-meal tiredness, so it’s important to differentiate between food allergies and carb crashes .
