Q: Being Indian, i dont eat meat every second day or so. Should i experiment with mass gainer shakes?

A: I would avoid commercial mass gainer shakes. Check out http://www.mikesfitness.com/content/protein-supplements for my reasons -- it basically comes down to the fact that most of the calories in commercial weight gainers are simple sugars which are rarely if ever a good thing (only exception might be right after weight training and even then I don't think they're the best choice).

As long as you are able to get enough protein (about 1 gram of protein per pound of bodyweight daily is a good goal) through regular foods, even vegetarian ones, that's good enough. If you are unable to eat that much protein daily, then I would recommend supplementing with whey protein shakes as opposed to mass gainers. Whey protein will have almost all calories come from protein with only a tiny bit from carbs and fats. On the other hand virtually all mass gainers have 60% or more of calories come from carbs and in virtually all cases those carbs are pure junk sugars. They are often advertised as "complex carbs" but if you look at the ingredient list you'll probably see maltodextrose or maltodextrin -- these are technically "complex carbs" but in reality your body absorbs them just as quickly as simple carbs with all the same negative consequences.

So, bottom line, if you get enough protein from regular foods that's all you need. If not, consider supplementing with pure whey protein. If you want to make your own weight gainer shake, here's an idea: http://www.mikesfitness.com/content/node/20023 -- obviously this recipe has a massive amount of calories, so you can change it as appropriate for you. I would definitely avoid commercial mass gainers.
