It’s important not to overeat at lunch. Eating too much increases your blood sugar and can cause a depletion in your energy.
Steer clear of foods rich in carbohydrates and protein, as they are notorious for making you feel drowsy. Some of these foods include pasta, salmon, rice, cheese, chicken, sugar, and eggs. Be sure to eat plenty of healthy snacks during the day to keep yourself fueled and avoid eating a too-big lunch.
