Last 3 weeks of insanity Need some Support

Managed to lose the weight that I put on from the holiday in a week yaayy, but disappointed I haven't lost any more I guess looking at the positive I have 3 weeks to lose 7kg (around 13lb) that's my aim for the end of round 1 of insanity...please keep me motivated guys!!

Im not just doing insanity I do a bit of other exercises throughout the week and figured I can lose 2kg in a week (I hope that's not unhealthy!) If my aim is ridiculesly high please let me know and help me get through my first round!
