I don't need to be overly accurate on this in order to hit my goal.
As a general guide if you target 1.5g of protein per lb of body weight you will increase your muscle mass.
My previous experience tells me that if I can do this then the calories and everything else pretty much sort themselves out.
So the protein target will be around 330g per day. Ideally I'd like a split of around 35, 50, 15 for protein, carbs and fat.
Now I could plan my full day's intake meticulously. I've got plenty of time though so I'll sort it over the next few days.
I'll itemise every food item plus it's calories, protein, carbs and fat. I'll then adapt this every day until I hit the sort of figures I'm looking for.
7.00am - 4 weetabix + 200ml milk (338, 15.4, 61.4, 1.8
)
10.30am - Pro MR (255, 42, 18, 1.9)
12.30pm - Terrible lunch (800, 40, 70, 40) estimates. Won't be a problem tomorrow because I'll know what I have
4.00pm - Flapjack (287, 18.8, 37.4, 6.8
)
6.30pm - Pro MR (255, 42, 18, 1.9)
9.00pm - Dinner 150g chicken, 150 mixed veg, sweet chili sauce, 50g rice, 3 x pitta (1156, 60.8, 192, 13)
Now this little lot amounts to a total of 3000 cals, 219g of protein, 397g carbs and 65g of fat for a split of 32, 58, 10
So although at first glance it seems a reasonable amount of food I'm still well down on the intake I'm looking for. Obviously lunch was a guess and I'm still having one more meal but I still need to eat a lot more.
When I was big I was consuming around 5500 calories per day with 350g of protein.
I need to adjust today's intake to get a bit closer to my target which is similar to that. I'll be having one more meal tonight before bed but other than that it'll be supplements which push me towards the target.
I've made myself a little spreadsheet to work everything out and I can get somewhere near by adding the following:
Supper - 6 egg whites, 2 egg yolks, 4 slices bread (605, 46, 80.8, 9.6)
Pro mass shake - (391, 36.2, 55, 2.9)
Whey protein shake - (200, 39, 2.4, 3.

This gives 4300 cals, 340g protein, 535g carbs and 81g of fat for a split of 36, 55, 9
If I then change lunch to a more healthy 4 x slices bread + 150g chicken + salad I get:
4100 cals, 354g protein, 545g carbs, 46g fat for a split of 37, 58, 5
This shows what a huge change it can make just swapping 1 meal. I've suddenly gone from 9% of my daily intake being fat down to 5%
