At clinic n weighing machine shows 91kg, at home it was 89.5 kg last night.. this is so sad

Stlll doing keto and IF?

Did the dietician go over your daily food intake? Did they make any suggestions?

Anything else that may be masking scale weight loss? Fluid retention? Been excercising a lot lately?

Do you know if you are losing inches/centimetres? If you aren't already may be useful to use body measurements they can be motivating when the scales aren't going down.
