Weight gainers are that they make meeting your calorie requirements much easier. If you're what's considered a 'hard gainer', someone who feels as though they have to eat and eat and eat in order to put on any muscle mass whatsoever, there's also a high chance that you're someone who feels as though if they have to look at another plate of food, you may just be viewing your last one shortly thereafter. Meeting the extreme calorie requirements that many men have proves to be incredibly trying and a weight gainer makes this far easier. If you consider the fact that there are weight gainers available that pack in over a thousand calories per shake you can quickly see how much more effectively you could reach your 4000+ calorie needs per day.

Specially Formulated Fats Help You Stay Leaner - A second big benefit to using a weight gainer is that many come with a particular type of dietary fat that helps to keep you leaner while you go about the muscle-building process.
