The calorie burn is quite tricky to interpret. At its most basic, weight loss or gain is a function of calories in versus calories out. If you eat more than you burn during a day, you gain weight, and vice versa. But the problem is that you know only how many calories you burn over 20 minutes. What about the other 23 hours and 40 minutes!!! And also, you don't know with much accuracy how many calories you are eating per day. And then finally, if that wasn't enough, there is an issue about how accurate that value is anyway - it's just an estimate and it's possible that you could be burning 100 or as many as 200 Calories, in extreme cases. And so a lot of people try to lose weight by couning their calories, trying to take in fewer than they lose, but this is ultimately a defeating exercise. It just is not practical.
So my advice is to continue doing what you are, combine it with a decent, sensible eating plan and you should achieve results. But you should also focus on getting fitter, rather than weight loss. For example, in a month from now, you should be doing more than 8 km, in 20 minutes. You might even consider doing this session for 30 minutes, not just 20. That could also help you achieve results.
