Falls under #1 but starts invoking specific foods in such a way that ultimately ends up confusing people in my experience. Better phrased as a reminder that drinks have calories, including alcohol and soda.

Sure, but it's not all about the calories. Alcohol and sugar makes the body store excess water. You swell up. Makes it hard to show of muscle.

Very true, I shy away from that specifically because it starts veering into pure bodybuilding practice — the rationale for that leads to the conclusion of avoiding hydrating as much as possible (which sounds silly, but I saw it with a couple clients, and am not ashamed to admit I get a little giddy when I realize I'll claim a pound back the next morning weigh-in when i realize I'm dehydrated at night)

Makes it easier, sure, but not absolutely necessary.

I regularly have alcohol when I'm cutting weight. It just gets counted towards my calorie budget.

I do find non-diet soda to be completely wasted calories though. Just not worth it.

i did get a 6pack with 1 glass of red 4 days a week. i also ate about 1800 calories a day and was working out 1 hour daily soooo ymmv
