Strength / Weight Training

I read an interesting article about only consuming protein before lunch as the effects of the protein work best after a workout. And subsequent protein didnt really do a lot

You're not there yet, this may be relevant to elite/trained people to a marginal extent but for someone who is just starting 5x5 you're over thinking it.
My advice would be to look at your daily and weekly totals - as long as you're not doing anything silly like eating all your food on the 7th day you really won't notice much of a difference when you consume your protein.

The first few months of your 5x5 gains are going to be CNS adaptations, you're 14 stone so you have the muscle mass there to cover the first few months of progression, your body is just learning how to use it. Once CNS is firing optimally you'll start adding muscle and need extra protein but at the moment your body isn't thinking "oh shit, I better put on some muscle size"
Lift, eat donuts and pizza 🍩
Starting to bulk now is good, means you'll be ready to cut come early spring ready for summer hols guns out.
