I would never recommend training that way. You are misinformed about the best rep range for fat loss--high reps aren't necessarily better for fat loss because there's less metabolic impact with the lighter weights used.

Stick with the standard rep range (5-12 reps) and train a muscle group about every 3-5 days (more often if you are just a beginner). Fat loss comes through diet and adding a little extra cardio if needed.
