Hi. I am also new to the site and have about 25kg to loose. If you are loosing weight and your body fat percentage is still high it could indicate that you are loosing lean muscle and not actual fat. To correct this you need to eat more protein at each meal. There are many sites that will help you calculate your daily protein needs.
You could also maybe have a look at the zone diet. It has a 40:30:30 ratio for each meal (Carbs: protein:fat). Also, you may want to look at doing some resistance training to build some lean muscle which in turn will burn body fat.
Hope this helps.
