Is One Approach Better?

Hi, everyone this is my first post here and I was hoping I could get some help. I have been lifting for a couple of years but only for the past year have I been serious. 

My question is what would be the best approach for losing 15 lbs? would split w/o like push pull work or would a full body approach be better? As for diet I will be following t-dawg 2.0.

Any advice is appreciated

In response to your question, I find full body easier to decrease body fat due to the high metabolic cost of these workouts.
Incline treadmill walking, sprints or circuits on days off…

Either way, STRICT adhearance to diet is the most important factor in weight loss if you are training 3-4 times a week…

a couple more questions when doing a push pull leg work out how many exercises should I do? the same with full body how many exercises is best?

Do you mean doing push’s, pulls and legs in the one workout?
Or
Push’s and legs in one workout and pulls and legs in the next workout?
