Carb-Heavy Meals

Eating high-carb foods such as rice, pasta, and potatoes can make you feel sleepier than other types of food. Although carbohydrates are a vital source of energy, the amount and the kind of carb you consume also matters. For instance, eating too many simple carbs (such as those found in white bread and soda) can lead to a drastic spike in blood sugar. This can leave you feeling sluggish when your blood sugar levels come crashing back down.
