Yes, your goal is okay but 5 kg= a bit over 10 lbs and that's a lot to lose in a month.  Better give it 2 or 3 months. 

If you're not doing a lot of exercise at this point in time it's best to look at one of the couch to programs on this site.  Pick whichever sport is most enjoyable to you since you don't have anything at this point in time.  Go easy, start with walking and add in jogging if you feel like it but slow and easy to introduce activity until you've adapted to it.

There is a weight loss board if that's all you want to look at.  This board is for the monthly challenges which are a lot of fun in themselves.  The April challenge is a multisport one (pick 2 or more things to challenge yourself in).  If you're pretty inactive right now I'd go easy like 30 min walking 3x/week and perhaps some core work with yoga or pilates once a week.  That would get you assigned to a team and meeting more folks on the boards. 

I took a quick glance at both options.  The Sprint 2x Balanced is pretty clear that if you cn do the minutes in the first week then you can do the program.  If you aren't able to do that much volume starting out then the couch to program works better.  I am pretty sure that if you can run 1.5K and swim 1K continuously you can do the first program.

Good luck and happy training!
