Myth: 

Three square meals per day is the golden rule of good health.

Actually, 5 or 6 meals daily, spaced out 2-3 hours apart, is the best strategy.

Rather than just eat by the clock or when you are hungry, you should attempt to consume all your meals in a 15-18 hour period. This allows you to maintain a consistent level of energy and blood sugar.

Each meal should contain the proper ratio of protein, carbohydrates, and fats. Base your meals on what you will be doing for the next three hours. For example, you will be expending more calories during a workout than watching television, so your pre-workout  nutrition would have more calories than your last meal of the day.

And don't forget training is an important part of health!
