I'm in a similar situation, I go on holiday a lot and as I'm at maintenance I eat what I want, gain a few pounds then it used to drop straight back off once back on plan but since Sept my weight has gone up a couple of pounds every time I've stopped keto, for my holidays but after reviewing how I'm eating I seem to be having more "baking" type dishes, nuts, almond flour etc so at the moment I'm going back to basics meat & veg to see if the pounds will start moving again but it is hard to give up the fathead pizza and 90 second bread.
Fingers crossed the scale starts moving again as I'm away again in April!! I wish I could stay on keto but I like my cocktails too much and hate keto hangovers!

Cutting out sweetened things, so no more baking with coconut, almond flour and sweetners, no more snacking on nuts because they're easy to overeat but trying to have lots of meat, chicken and fish, coupled with veg such as celeriac chips, sprouts and cauliflower are my go to's. It's difficult as I'm only 5'1 so can't eat all the fat laden stuff I see on FB groups.
I'm doing IF 16:8 as much as I can too, I find keeping busy helps, I don't " boredom" eat as I'm never bored as such but call it "unoccupied eating" sitting around on Sundays it's hard to IF but if I'm at work it's easy as I'm busy and as long as I drink water I don't get hungry, I make sure I keep my electrolytes up.
But I think the only thing we can do is take one day at a time and hope the weight starts dropping again at some point, another positive is we're not doing SW or WW where we would be starving all day, least we get to eat nice food and not feel totally deprived lol

Photos of the old you are great reference point, so are measures! I’ve been at a standstill weight wise for about 6 months, so I pulled out my “motivation photo” and old measurements to remind myself of the difference this woe has made... I’m just about to start mixing up my exercise to see if that will get things moving... I know that carbs don’t work for me, so something else is due for a change

I track my food pretty consistently so when I notice scale creep I am pretty sure I know what I have been doing to cause it. I've stalled now for quite a few months but my exercise has tapered off some due to work and school so come May I will probably start to lose more weight and tone up once school is done for the summer. I am just happy to maintain a 41 lb weight loss with everything that has been going on around me lately.

My best advice is to work through the weight loss stalls, heck don't even jump on the scale for a while and just concentrate on doing the things that helped you lose the first 20 lbs. Scale stress can be a vicious cycle where stress can derail your best efforts. Keep up the good work and remember this is for the long haul, that is what I tell myself to stay motivated.
