I would say eat the same whether you're training or not. (At least that's what I do).
Take your BMR at rest and active and average them.
(for me that's about 2800 cals/day). then add your surplus or take back your deficit.
Now, you can do 144 g of protein a day, but you might want to do a bit more. (still, let's say you keep it there for the time being).
144g x 4 cal/g = 576 cal (of 1882 you say you have available)
then we take in fats. I like taking in a LOT of fats (literally doing ~130 g/day, but that's a LOT, I just would rather have high fats than really high carbs)
Anyway, let's say you're taking in 85g of fat (which is what my mealplanner actually recommends for me, 6', 175 lbs)
85 g x 9 cal/g = 765 cal (of 1882)
at this point we only have carbs left. Let's take the 1882 - 576 - 765 = 541 calories left.
This is going to be
541 cal * (1/4) g/cal = 135.25 g of carbs.
So your totals come out to
144 g protein, 85 g fat, 135 g carbs
That's not bad at all. However, it's going to be hard for you to come all the way up from 60-70g of protein to 144. Take it slow if you need to, just get your body used to it and you'll do great!
For me, my totals are:
233 protein, 399 carbs, 82 fats
but I give myself some leiniency and try to hit anywhere between that and
308 protein, 307 carbs, 85 fats. It is hard for me to eat 400 g of carbs every day. Sometimes damn near impossible. However, I can always chug down a double scoop of 30/8/3 per scoop protein and call it a day.
as long as I hit my caloric intake goal every day, I'm happy. I also like hitting my protein macro every single day. But I will vary my carbs/fats as long as the overall calories stay the same, but I like to eat really clean (my fats come from nuts, avocado and meats mostly and then a little bit in my coffee for creamer)
Even then, still monitor your bodyfat % guesstimate and your weight. you will absolutely know when you're dropping bf%, it's just one of those things when you look in the mirror and just feel it. It also helps to keep a "before" picture of yourself as a reminder for motivation and comparison. I know I've been eating at ~300-400 daily calory surplus, but I still lost about 2 lbs over the last two weeks so I might have to up my calories even more because BMRs are just a "guesstimate" and the math can't know how your specific body deals with the different macros and how effective it is when processing them but it's always a good place to start!
