To beat mid-afternoon drowsiness, make lunch your main meal, and eat it away from your desk. Choose foods with variety of bold flavours (like salty, savory miso soup with tangy teriyaki or a spicy bean burrito with salsa). Emphasize vegetables, beans, nuts, chicken, or fish, and go light on simple carbohydrates like white bread or white rice. End with a healthy sweet (like a small piece of dark chocolate or candied ginger). Follow this advise work-man promises that you’ll be more productive after lunch.
