Good Luck Anthony! 85 lbs in 5 months is going to be a difficult task. You need to be careful about losing weight that fast, it can cause all sorts of health problems.
I know that Paul lost like 80lbs just but cutting out soda out of his diet, so that's deffinately a good place to start. Also, negative calerie foods is a good thing (carrots, celery, etc...) Even walking on the treadmill or elliptical is good, working out period allows your metabolism to raise which will allow you to burn fat even while sitting still...
Again, good luck man!
