You don't have that much to lose, I'm sure you will make it.
What I learned and works for me is eating a fruit every 2 hours to keep my metabolism going. What's funny is eating a lot makes you lose weight (the RIGHT foods, no McDonalds) because it tells your body it doesn't need the excess fat, that you have plenty of food so it burns it off.
If I may suggest, you should run for 30min-1hr daily (on top of your workouts). In my opinion, running/jogging with HIIT is the best cardio workout. Hope it works out for you.
