Congrats. What this means is your metabolism is in overdrive and starting to burn off all your excess fat. Drink a lot of water with your meals. Also you should be eating about every 2-3 hrs anyway so it's not that far off. If you need to start eating slower digesting foods with complex carbs.. Oatmeal,rice,pasta,potato etc. Just watch the calories since they normally have a bit higher calories. Add 10% calories to your meals see if that helps lots of little things.
Just if you want to burn a lot of fat yet. Just focus on drinking water and eating 0 foods.. Like vegetables. If you aren't to tired or worried about losing weight just up your food intake til you are comfortable. You can also just suffer and know that all your hard work is paying off
