I think that article has some ok basic information but it lacks any kind of detail. Instead of saying the average person burns 1800-2200 calories a day put in something that shows how to calculate you maintenance calories. If I only ate 2700 calories a day I would not gain any weight at all. As a matter of fact I eat almost twice that any calories and I only weight 179 pounds. Also, the 2 grams of protein per pound of body weight should say 1-2 grams of protein per body of lean body mass. IE you don't need to feed your fat protein. Also, you don't mention much in the way of what exercises are good for mass. You need to add the words squats, deadlifts, cleans, bench, rows and pull ups somewhere in that article. Maybe elaborate on the progressive overload and how to properly periodize a workout. There's a few suggestions for ya, good luck with your writing.
