It’s individual. I drink much coffee (all day) and I need to drink most of them black. After only 8 years on low-carb and training myself to it, I finally can do that with the right band if it’s very weak… Sweetener was easier to skip, it only took a few years to gradually lower the amount but I had no problems with xylitol and later erythritol, actually. Some people do. Not the same but sometimes helps if I just drink tea instead of coffee, that’s nicer without adding stuff, I learned that tea usually should be consumed without anything decades ago.
And there is always water. If we can’t drink coffee without a ton of cream and we can’t afford a ton of cream, coffee is out. Life is hard sometimes
I am a hopeless coffee addict so I learned to drink black coffee, I do IF anyway so cream should be out (sometimes I don’t care and use a few drops but I like to keep that close to my eating window).
I can’t afford much cream as it has very much fat that doesn’t satiate me at all. It seems cream and added fat satiate most people well, their attitude is different, of course. If you can afford the calories and macros and you consume it when it’s okay for you (not in the middle of a planned fast, for example), you may use lots of cream. But there is always a limit. To me, 10ml heavy cream is a good day (and it’s enough for quite a few coffee for me. unless whipped. I probably could drink a coffee with 100ml whipped cream just fine
I don’t do that, I put an egg and a little cream into my coffee if I want it more substantial). 20ml is okay but I shouldn’t go beyond, usually. But if I manage to get satiated with little enough food on some day, I can afford more, not like it has much sense, I could eat some proper satiating food with it, not risking getting hungry earlier the next day. Occasional bigger comsumption is fine too if you can balance it out with stricter days. So try out things and you will see. But overeating from cream surely won’t help with fat-loss and gain is possible. So some moderation should be used.
Sugar is the worst idea. One on keto should never add plain sugar to anything - well except if someone NEED sweetening and hate all the sweeteners and they do what they are doing? But sugar in every coffee sounds one of the worst ideas ever. Even on simple low-carb with a more generous carb limit. Even my health conscious high-carber SO avoids plain sugar… There are usually way better options without a big (or in lucky cases, any) sacrifice.
2lbs is nothing, one can gain that in an hour and lose it too… Our bodyweight fluctuates.
