Go gradually, buy a log to record all food intake, supp intake, weight training, and cardio.
Try to only alter one aspect at a time. For example, don't cut carbs to 50 grams a day and include 1 hour of cardio a day all in week 10, that will destroy muscle tissue. Try cycling carb intake, focus on carbs for breakfast and post training only. Still keep veggies in diet(fibrous only). Try to avoid fruit.
Frequent meals is very key, shoot for 8 per day. Use real food as much as possible and try to limit yourself to about 6 different foods total so you can figure out exactly how they will alter your physique. (this is a crucial step in the final weeks.) For example, chicken, egg whites, oats, yams, broccoli, lettuce. Just make meals out of those foods.
These are very general tips obviously, hopefully of some use though!! Good luck!
Pain is temporary, pride is forever!!! remind yourself of that during the next 10 weeks.
