I relate @OP . Since I predominantly quit drinking three years ago I've stopped going to the pub with friends as I used to. I still chill with people, though whilst they're getting drunk I just drink water. Perhaps that's something to consider. Some conversations tend to be better with booze or weed or whatever else and if you're not on the substance they may be a bit boring or difficult to relate to. But my friends and I still mostly have the same senses of humour and i still enjoy just sitting around chatting and having a laugh. Perhaps in my case, it's become clear that we still relate to one another and make one another laugh. Perhaps if you convinced your old friends that were the case then they'd be happy to have you around, even if you're not drinking.
My eating routine, particularly on the days when I go see them on short notice having intermittent fasted all morning, can be troublesome. However me popping out for half an hour for something to eat is rarely an issue. As for you, your friends and any wings or burgers etc they want to get, perhaps you could try incorporating some iifym on those days. That's what I do now. Tbh I genuinely prefer eating healthy over eating junk but some occasional chicken wings aren't that bad. White bread won't wreak your metabolism either. Incorporating 50g of poorly sourced carbs and fat into a healthy diet isn't difficult and the worst case scenario is that (assuming you're cutting or recomping as I am), you'll 'only' be at a 100-300 calorie deficit or maintenance for the day. In the grand scheme of things that translates to me gaining a teensy tiny bit more muscle (smaller deficit thus more retained) and having to diet for an extra day. It's not that bad
On the topic of clubbing. We have the same definition of 'clubbing'. Some of my friends like going to clubs where folks seem to just go to drink, sing along to songs and possibly get laid. Singing along to songs is more fun when you're drunk and so given I don't drink, i can feel a bit out of place after an hour or so. When I'm lean I model and people often tell me I dress well. I turn up, dance a bit and 8s 'magically' appear around me and want to talk. But truth be told I'm not one of the hornier people in this world. I'm into hip hop and trap alongside techno and house but I prefer clubs where clubs spin house and techno. Going to clubs people go to to drink, sing along to songs and possibly get laid, when you're not in the mood is a bit off.
For this, you may just need to find some new friends. On the brightside though, finding new friends could be fun. Most of my old friends are into mostly the same music as me but they don't like clubbing as much as I do. So I've been making new friends who like clubbing more than my old friends. When my old friends and I want to go to the same night, sik. Though I'll also go with my new friends. I'm keen on the two groups meeting one another
What I'm saying is, perhaps you could still chill with your old friends whilst making new friends.
What do you do for work btw?
I try not to mention fitness related things around the friends of mine who aren't into fitness, which is 95% of them, but that's alright because we talk about other things. It'd help you to remind your old friends of your similarities as opposed to reminding them of your differences. Also, try not to slam unfit people. When a person's buddies aren't fit, they probably won't like being around someone who slams unfit people. I'm being frank here but the above is what my life's taught me
