I've been bulking at 3500 calories with ~210g protein, rest carb/fat distribution and recently started a cut at 2750 calories ~210g protein, a lowered carb/fat distribution and cardio.

Should I still be pushing as hard as I do when bulking? Or will the muscle not fully repair if I'm doing it at a deficit? A content creator ate only protein for a week and lost an incredible amount of muscle doing so, though that's an extreme case. I'm still eating ~250g carbs and ~100g fat a day. Title.
