I would start out, at least for the first month or so, with full body, 2-3 X week. Get used to the feel of the motions. 1-2 sets to start with are just fine. I would advise circuit style, exercise 1 right after exerise 2, etc, at a fairly quick pace, as fat loss is your goal. When you do decide to add a seond set, go through the lineup once in a circuit, then rest, and go through the circuit again. After a month or so, you should be pretty well broken in, and can choose at that time whether to split or not, and to go with a "set" approach, that is staying with one exercise until all sets are complete. Just my recommendation. This is what they call a prep or adaptation phase in a periodized program. It breaks you in, gets you used to the movements, builds up work capacity, and aids in fat loss by emphasizing gh producion with the quicker rest breaks (try using 60 seconds or so between exercises).
