1. Convenience: Let's be honest, with most people working full-time, how can one expect to realistically eat 6-8 meals per day in this day and age? This is where the protein powders can certainly aid in permitting greater time-management and efficiency.
   
   
2. Caloric-Density: When loosing fat, one has to be in a caloric-deficit to deplete fat stores. And since in caloric deficit, protein needs are greater to prevent catabolism of endogenous protein (Lemon & Mullin, 1980).
   
   Most foods have hidden carbs and fats. A protein powder has some carbs and fats, but it is not hidden. Ultimately, it comes down to control over your food intake and with a protein powder, you know exactly what you are eating.
   
   
3. Supplement Science: Most research has shown that protein supplements improve strength, nitrogen balance and body composition. However, some research has shown protein supplement usage to be suggestive or inconclusive. Supplements merely add a small piece to the tip of the iceberg. However, this small advantage could be what makes all the difference.
   
   
4. Variety: Lets face it, eating loads of meat can be quite a monotonous experience. Protein powders today taste better and can provide a nice variety to one's protein source selection.
   
   
5. Window Of Opportunity: With bodybuilding, timing is critically important in terms of eating frequency, amount of carb, protein and fat intake with respect to timing of exercise, pre-workout meal timing, post-workout meal timing, etc.
