There is no reason you should have to give up ice cream. One scoop every other day isn’t going to affect your weight loss at all.
Hell, I love ice cream too and back when I first started IF I was eating a scoop nearly every day.
As long as you stay under your TDEE, you’ll be fine
I do find greek yogurt (I use plain, but could use anything), mixed with frozen berries is great. I make it with my lunch, stir it up and by the time I’m done lunch, the berries have thawed a bit and the yogurt around them is frozen and its like a tart (would change if you used a sweeter yogurt) ice cream. Its a good protein/low cal option, but feels desserty
Find sugar free cones, buy 1 pint of keto enlightened ice cream and make a double scoop for yourself and one other person…
Split the total calories in half, even if it’s like only 2g carbs per serving or per pint
But the best method is really buying all types of fruit, I found also sweet potatoes basically taste like candy.. so I’m pretty happy giving up ice cream. I used to go through a pint a day this past winter
