I mean it’s close to doable but you’d be pushing what’s healthy in terms of weight loss. The problem with rapid weight loss is mainly yo-yo dieting. You usually use a fad/crash diet that isn’t sustainable long term and then gain it back. Lifting + some cardio is the best bang for buck in terms of calories burnt for most in terms of time/effort.

The boozing is a problem for a couple reasons (beyond the obvious reasons, but I’ll spare you the sermon there). One beer is ~112cal. Maintenance for me was -2200cal back in the day. Drinking ten beers, which back when I was boozing was enough to get a buzz going. That’s 1120cal, eating at a loss for me was 1600-1700cal if I recall. So one night’s buzz undoes 2 days dieting, at least.

If you then eat to account for it, you run the risk of getting most your calories from booze, which can be incredibly harmful for you long term, I.e. deadly I’m pretty sure.
