I'm obviously not your target response, but I would tell them that since they were a beginner that they should start and keep a food log to check the macronutrients and bring their diet in line with whatever goals they had in mind (a search would lead to some of Dr. Beradi's guidelines OR you can click on "ARTICLES" over there on the left hand side of the screen <--then click on "Diet Programs").
Since they don't know how their body responds to different types of weight training, I suggest that they find out. I would suggest that the person search for and obtain several of the methods and routines outlined on this site (Look over there at "ARTICLES" on the left hand side of the screen <--then click on "Training"). They would then perform a specific routine for a set length of time, record progress, and then switch to another routine and repeat.
