It is nothing to be concerned about. Step away from the scale and just focus on doing things right. I know that is easier said than done, but the scale isn't going to be a good representation of what is happening in your body right now.
As long as you are following the guidelines and doing the right things, you ARE burning fat, and your body composition IS changing for the better, even if it doesn't show up on the scale. There are many factors that make the scale go up or down in a given period of time. This will not be the last time you wonder what the heck is going on as you work toward your goal.
The best thing you can do is continue to make the right decisions and when you get back to eating regular food, focus on creating a new relationship with food and creating good habits that will help you maintain your coming success for the long term.
It's hard not to want things to happen very quickly, but for most of us on this road, there are multiple ups and downs with fast progress and slow progress, and it can come at any time. However, as long as you are maintaining a calorie deficit, choosing good foods, and maintaining hydration, your body will release fat over time. It will happen.
