Hi Green,

Welcome to the forum. Dental school? I hear that's a b!tch to get into.

There's nothing wrong with the foods you're eating. What you'll need to do is keep track of how much you're eating as well. Three meals a day and a small 4th before bed is fine at this point. Shoot for 3000 cals a day, spread out over your three meals relatively evenly, and monitor your weight. If you're not gaining 1-2 lbs per week at the moment, up your cals to 3500. If that doesn't get it moving, up it to 4000. At some point, you'll want to start spliting meals up and and eating 4 or even 5 meals a day instead of 3. Don't forget your small extra before bed. You should be able to gain 1-2 lbs per week for 12 weeks or so without much concern.

At this point I'd forget the supplements totally. Weight gainers are usually convenient but expensive, and Glutamine is well-hyped but that's it. Creatine, well, at least learn how to gain weight without it before you add it to the mix. You may find, like I have, that Creatine doesn't help over a solid anabolic caloric surplus.

Protien powder is a good choice, however. It's convenient and cheaper per gram than other sources. Use it pre and post workout if you want, or when there's just no time to prepare something to eat.

That's my advice anyway. Hope it helps.

Cheers,
Jeff
