Gaining

Try losing ten pounds or so. People usually gain back more than they lost.

Don't give up keep trying, it will come. Someone said about losing ten pounds, I don't think you have to do that. You could try backing off on your intake for a few days to mess with your metabolism.

This works for me when I hit a plateau.
I do a drastic diet for a week, like the egg diet as it shocks my system. I then hit it hard with high calorie days and the weight goes without any problem.

Really makes me wonder if that someone actually tried it.

Once I tried mixing in maltodextrin powder.. whether it's pure maltodextrin or is mostly it (like a lot of weight gain powders are), it seems to clump up SO bad when mixed with dairy fat. Forget about ever being able to drink it. I had to throw out the mix.

So unless there's some trick to it that I don't know, I can't imagine that working out very well.
