Many people believe that calorie intake is the key component of a healthy diet and the most important factor in determining overall body mass.  While that is absolutely true, I believe that attention must also be paid to the macronutrient content of a person’s diet (ratios of protein, carbohydrate and fat) in order to optimize body composition, energy, strength, and sexual function.  While each macronutrient is important, I believe that particular attention should be paid to protein consumption.
