Well I'm glad he's taken my advice on board, as I always tell people to use lean weight when doing diet plans as that's what I strictly stick to and my gains have never failed me.
And THETRUTH I know what your saying but why are you set on 40%?
Let me use an example:
A 190 lb man at 20% BF,
Weighs in with 152lb LMBW,
Let's use 18 Kcals per pound of LMBW for example
So he needs daily, 2730.
I your saying eat 40% of calories from protein he would require 1,092 calories which is 273 grams of protein.
That is 1.7g every pound.
Now if we used TOTAL body weight then that figure would raise dramatically to 342 grams which is overkill that's is almost 2 times his lean mass. See what I'm getting at? That is why I'm so set on using lean weight. The diet must be looked at on a whole and adjusted throughout the cut to how you require.
So for cutting SOS I would first try 15kcals per lb of lean mass to get your calories for the day an adjust depending on your progress,
For example if you were at 20% BF you would need 2280 calrories per day, whereas a lean bulk at say 20kcals you would need around 3,040, so it's quite a difference.
But at 2280 call it 2300 you'd get
608 calls from your 152 grams of protein,
You still need 1692 calls
So if you had 30% of that as fats you would require 57grams a day which gives you 508 Kcals.
With 1184kcals left that is 294grams of carbs a day, if you start at this you can monitor and adjust accordingly, obviously I don't know your BF% though and you might have less than 152lb lbmi, so your calorie intake would reduce again.
