Good on you for losing 16kgs!! That is great!

IMO a kg a week when you have already lost a fair amount of weight is a big ask. I know you have a goal but it is better to aim for a loss of around 500g per week. When you lose larger amounts over a short period of time you are more likely to put that weight back on very easily.

Personally I would just keep doing what you are doing and tho it may take longer than you ideally, want the result will be better in the long term.

Sorry if this is not what you want to hear

Keep up the great work.
