Iscariot, as usual, is giving great advice. While I love the delicious taste of meat, you can make the necessary choices being a vegetarian to accomplish all of your bodily goals, it just takes some more/less work depending on what it is.
Thanks, Badandy. And yeah, by Gandalf's beard I wish I fell into the "less work" category.
As for the whole "normal" thing: is it really something you'd want to do? I mean, the numbers on "overweight" and "obese" in America and Canada are pretty crap.
And unfortunately Hummer didn't give his weight, so there's another deficit of data.
Well you do on some things. Telling you to lower your cholesterol is a hell of a lot easier than telling a meat eater to lower their cholesterol. Unfortunately, for the original poster, saying "You need to gain muscle mass" is harder than usual.
Well there are meat-eaters who are not overweight or obese, as you know. It's more of a lifestyle choice. For example, I will eat a cheeseburger (not McDonalds) at a restaurant with some fresh fries (not cooked with preservatives) and then go play two and a half hours of basketball the same day. The next day, I'll eat a turkey/ham/cheese sandwich and lift weights. Someone else however, who would still be classified as a meat eater, would eat at McDonalds and supersize their fries. They will go home and watch reality TV without getting physical exercise then complain about how them being fat and unhealthy is not their fault. We are both meat eaters, but it can be done in a better way.
From reading his posts, I'm assuming he does not get enough calories, which is a very bad thing if you are underweight.
Honestly, you're going to have to consider non-creepy, ethically-produced animal products (not necessarily byproducts), such as eggs and milk. They CAN be produced ethically--I grew up on a farm. Otherwise, you're probably not going to be able to consume the massive amounts of protein and get the full amino acid sets you'll need to synthesize quickly in order to build muscle or do a bulking- or cutting-cycle (a necessary process to gain mass). :\
But soy protein is a start... there's egg albumin protein protein as well if you can't handle whey.. but honestly real food is better. And real food you can buy from local farms where they have freerange chickens that you can SEE are freerange and healthy; same with milk; or if you are near a fish-producing area, maybe look into pescatarianism (you could totally bodybuild with only fish+plants).
Real food is always > than supplements.
