What's not often discussed, though, is the relationship between diet and stress. What you eat can affect your emotional well-being, as well as your physical fitness. For instance, too much caffeine can make you feel jittery and keep you from getting enough sleep. This can create a vicious cycle in which you're tired all of the time, so you drink more coffee, which makes you feel more on edge, and so on. Another problem is how much you eat when you're under stress.
Many people respond to stress by overeating.
Cut down on foods high in fat like eggs, butter, red meat and cheeses. They slow you down. Try to build your meals around complex carbohydrates like bread, rice, potatoes, pasta, fruit and vegetables. They give you long lasting energy. Cut back on foods high in sugar and salt like candy and potato chips.
