(Hang on, no way the rubbish I wrote below is right, I only ate 1.5kg of bread in total, that's about 150g of protein in total, how did I get 749 below.... I am not good at maths, let me think about it)
I could have just fooled myself somehow, I really didn't stick to it long enough to draw any firm conclusions, but assuming I didn't:
I think even if I went from just beef+potatoes to just beef+bread that would be quite a hike in protein terms
say 3000kcal/day so 21000 in a week
of which 2730 come from 1kg of beef 237g protein, leaves 18270 to be made up from
potatoes = 18270*0.022 = 401g
or
bread = 18270*0.041 = 749g
as opposed to
cream = 18270*0.0032 = 58
So ex150-cream is about 295g protein/week
ex150-potatoes is about 638g protein/week
ex150-bread is about 986g protein/week
And the minimum protein requirement for someone with shall we guess 80kg of lean mass is about 7*0.8*80=448g/week.
the pure cream version would leave me protein deficient by about 153g/week (probably why I can't keep it up for too long without longing for a pizza!)
the pure potato version leaves me about 200g of spare protein to get rid of
the pure bread version would leave me about 538 g of spare protein to get rid of
Tripling the amount of protein that needs to be destroyed might have quite a significant effect if PUFAs liberated from body fat need to go down the same path.
But in fact the version with chips also had lots of fruit and cream and butter
whereas the version with bread was mainly just beef and veg stew with toast and butter and veg
So I reckon I probably went from roughly in balance to 'oops I have to destroy half-a-kilo of protein' every week. That's much more than the amount of PUFA I need to destroy even if I'm losing a kilo of fat a a week.
Also the numbers in my comment above don't seem to make much sense! I'm still trying to debug them. I wish I was better at maths. I feel a post coming on.
Not sure, I've never actually eaten just beef and potatoes, there's always loads of butter and cream in various forms involved. We might not be too different. In fact since you're both a larger and a younger man than I am I'd expect you to need more protein.
I don't do much intentional exercise these days but I tend to cycle and walk everywhere (say half an hour's moderate exercise every day)? Is that more or less than you?
Protein yes but I do want to point out, wheat itself bothers some people more than others. The same amount of additional protein from beef vs bread affects me differently
It could be that bread (or wheat more specifically) is bad/inflammatory. Lots of people think this.
For example potatoes have nearly the same amount of protein as bread, and you were eating loads of those?
You could try to recreate it by eating a similar amount of e.g. white rice.

From the bags of the actual things I was eating:
----------------------------------------------------------
Tesco Maris Piper Potatoes have 1.8g protein / 100 g, and that's 81kcal
Jason's Sourdough Bread has 9.7g protein / 100g and that's 237kcal
Sainsbury's 80/20 beef is 23.7g protein / 100g and that's 273kcal
Sainsbury's Sour cream is irritatingly given per 100ml at 2.3g/100ml and 171kcal
Tesco's Double Cream is 1.5 and 467, again per 100ml
Waitrose Essential Salted Dairy Butter 0.5g protein per 100g, 737kcal
Tesco Valencia Orange Juice Ice Lollies 0.7g protein, 92kcal
Haagen Dasz Vanilla Ice Cream 4.3g protein 250kcal per 100g
-----------------------------------------------------
So in order of proteinaceousness
Beef 23.7/273=0.087
Bread 9.7/237=0.041
Potatoes 1.8/81=0.022
Ice Cream 4.3/250=0.017
Sour Cream 2.3/171=0.013
Lollies 0.7/92 =0.0076
Double Cream 1.5/467=0.0032
Butter 0.5/737=0.00067

Yea could really be the protein then. Really hard to control & normalize for it, since it's in almost everything, like PUFA haha.
Presumably your cutoff is between 90 and 140g a day then, whereas mine is presumably between 40 and 90.

Probably more. I take occasional walks, but they're not really exercise and not every day.

Yes, could easily be something bread-specific.
Haha had the same thought
