Hi Zvi from another UK member.
The fact that you have been the same weight for the last 2 months suggests to me that your body has got used to what you are feeding it and you are going to have to tweek things a bit to lose the remaining 5 kg.
Firstly, as already suggested I think the first thing you should do is increase your carbs to between 20 and 30 a day. I certainly lose better at a higher carb level and eat up to 50 g a day.
Secondly, the fact that you are in ketosis, however small, means that you are burning fat, however I suspect that your fat burning is coming mainly from the foods you are eating, rather than your body fat.
So, how many calories do you have each day? If you do not already do so why not use
Fitday to calculate your daily carb and calorie levels. There is also a useful thread about Fitday at the top of the newbies questions forum.
You should be eating around 10 times your bodies weight in calories. If you are eating much more then you are likely to be eating to much fat. I know that I do not lose weight if I eat over 2,000 calories a day and my current weight is 184 pounds.
However, do not be tempted to go the other way and do a low calorie version. That will not work either as your body will think you are trying to starve it and slow down so that you can not lose weight.
Thirdly, do you do any form of exercise? If you do then you should alter what you are doing to challenge your body more. If not, you should add some in whether it is a good brisk walk, gardening or something else.
I hope this helps and you are soon on your way to losing those last few pounds.
