Here's the thing. First, don't look at exercise as a weight loss tool, it's not. It's great for health and has many other benefits, but it's not that instrumental for weight loss. Keep doing it, but you don't need to do it every day, especially when you are eating very low calories. Speaking of calories, what you are eating is very, very low, and I would double check with a dietician. The combination of very low calories and exercising every day can slow your metabolism down, but that being said, I GUARANTEE that even when the scale is not moving or even when it moves up, you ARE losing fat and your body composition IS changing.
You may talk to your dietician about upping your calories a bit. You may want to choose different foods. You might not be eating bad foods, but they might not be right for your body. It's a great misnomer that the post surgery diet will be effective for every single person out there. We have to adjust and tweek to find the right balance.
Many people go through periods like this and then continue to lose. Some people lose consistently until their reach their goal, others are all over the place. There really isn't a "normal" way that it all happens. Averages are misleading. Stick to making good food choices, stay hydrated and if you are going to exercise, consider resistance exercise more often than cardio to help maintain muscle mass and metabolism.
Your body is changing for the better, no matter what the scale reads. Step away from the scale for a while and just focus on food, nutrition, hydration and activity. Work toward new lifelong habits that will carry you over after you reach your goals.
