I saw that you had 3 days of weights, so here is my suggestion.
Try 4 days of weight training with these splits:
Monday: shoulders and triceps
Tuesday: back
Wednesday: Rest Day
Thursday: Leg Day (no skipping this one!!)
Friday: chest and biceps
Throw some abs in there (though not everyday).

To avoid plateau'ing, have a training buddy so you can lift heavy and have someone to spot you to give the full contraction. Also, make sure that you mix up your workouts...don't do the exact same chest and bicep exercises every single week.

And: eat clean. If you clean up your diet, the weight comes off very quickly. Buy yourself a lunch cooler, tupperwares and tote your pre-made homemade meals around. If you don't know what I mean by eating clean, befriend a bodybuilder.
