Yes you should take carbs after workout.
No need for carbs except for breakfast, pre and post workout meals. If your first solid meal after workout takes place at 10 PM (two hours after your workout) then no problem at all, it should contain carbs, but avoid any carbs after that meal. I guess you wont have time to eat after that last meal.
Anyway it is very simple, carbs are +/- 1 hour around workout. That's it plus at breakfast.
For carbs always think about it as fuel. Work hard to earn your carbs and consider timing.
Again I see your 400g is very high even if you run, if we apply the math:
1 hour of running burns around 500 kcal if you run on high intensity
1 hour of brutal weight lifting with minimum rest between sets and high intensity (working above 75% of your 1RM) burns around 400 kcal
Total is 500 + 400 = 900 kcal
900 kcal = 225g of carbs!!!!!
I think you don't even burn half of those calories as you are still new to training. so no need for that massive amount of carbs. We need carbs as fuel and for its insulin-related action.
What are your states? weight, height, age, etc. How long do you train? What is your BF%?
