DIET & EXERCISE
The first step to putting on weight is eating more, lifting heavier weights to increase your muscle mass. The body works fairly simply, the amount of calories that are burned in relation to the amount of calories that are eaten affect weight. If a person eats more calories than they burn they will gain. If they burn more calories than they eat they will lose weight. For gainers the goal is to take in more calories and burn less.
While eating large amounts quickly seems like a great idea it might not be. When someone gets overfull they seem less willing to eat later, which will equate into less calories for the day. For individuals who get full quickly eating a smaller amount throughout the day is probably the safest bet.
A lot of weight lifters swear by things like whey powder and other shake formulas. Other find that it simply stores more water in the muscle, creating the appearance that one wants but it doesn't have a long term affect. If a quick result is what the lifter in question is after I suppose it's fine and it can be used to supplement a diet but don't expect it to create a long lasting effect.
