Let’s say that you are a 200 pound individual, so you were at
2200 calories (bw*11)
And let’s say a protein intake of 1.5g/lbs so that’s
1.5*200*4=1200 calories from protein
Leaving you with 1000 non-protein calories.
You said your fat/carbs are 60/40* meaning that last week you had,
600 calories from fat, which is about 66-67g
400 calories from carbs, so 100g
You are now furthering your deficit by 200 calories, leaving you to take out 100 calories from fat and a 100 calories from carbs, meaning you’ll reduce your fat intake by about 11g and your carb intake by 25g.
So, taking this week’s caloric intake of 2000, we remove the protein calories (1200) leaving 800.
We now have 500 calories of fat, and 300 calories of carbs.
500/800=0.625 -> 62.5%
300/800=0.375 -> 37.5%
*but at this point in the deficit I’d urge a higher carb intake, since I’m assuming you’ve leaned out. Also don’t stay at the 10 multiplier too long.
