How will losing weight affect my nose filler?

I have an appointment scheduled for nose filler to correct a droopy nose tip. I am also in the process of losing weight - I plan to lose 10-15kg over the next few months. I will do this by mostly intermittent fasting and doing 48h water fasts, both which have worked for me in losing weight so I know I will be losing weight. Will this weight loss or fasting affect how quick my filler breaks down at all? As I am 1) losing weight and 2) skipping meals.
