While you may have to change things to get things moving, it's also possible your body may just need some time to heal.
There are a couple different strategies that are popular, especially Leptin Reset, IF, high-protein/moderate fat with calorie counting and calorie/carb cycling. If you feel you've healed completely and are still not seeing fat loss, you could try each of these until you find something that works for you(warning: people here often feel *very* strongly for and/or against these).
Also, what are you doing for exercise? Posting a couple day's food might also help.
