The liver has 2 main functions, cleaning your blood is its primary function, and lipid movement is its secondary process. If you drink enough water and stay away from the alcohol (beer and liquor) you loose fat that much faster.

I am not a fan of high reps to 'tone'. I feel over 12 reps becomes useless and your lifting becomes a poor cardio session. I would stick with trying to lift heavy, cut rest times, and add an intense cardio session after your lift. Like 45 mins at 70-80% of your maximum heart rate. If you can, do interval sprints instead for 20 mins.

Tabata is the only exception for higher reps in my book. Try it for the next 4 weeks while dieting on a low carb diet. At day 15, mix in a high caloric day so your body doesn't shut down. Done right, that will get you cut and pumped for Blonde Box of Rocks and her friends.

Losing fat is about a negative caloric intake, just make sure at the end of the day you've taken in less than maintenance (use a rough estimation like 11xyour body weight) and you will lose weight.
