I found an study on the effects of low-carbohydrate diets on metabolism through my university's article database. When you search for something, it brings up a list of the titles of the articles, a short synopsis of the study, and it tells you whether it's peer reviewed or not. Well, the article I chose was labeled as peer reviewed, but I'm wondering what in the actual article will tell me that it is indeed peer reviewed? Is there any keywords or anything that will tell me? Thanks.
