I lost a nice bit of weight at the start of the pandemic when I stopped drinking (primarily a beer drinker). It is really surprising how much of an effect it can have.
Personally, while tough to keep that as an average weight, I was successful doing this, primarily by going to one meal a day, and limiting calories (especially carbohydrates). Only issue is your body does end up burning fat, which makes your feel a bit more “oily”.

If you are on the heavier side and a heavy drinker and carb eater, going low carb/no alcohol you will lose easily 10 kilos in a month (mostly being water weight).
If you are a healthy weight and eating normally with a glass of wine here and there, 0.5-1kg is probably a good range (and probably around 70% of it being fat loss)
If you are lean, 0.25-0.5kg a week is a good goal (and probably 50% will be fat).
