From looking at the macronutrient ratios that you posted, you will have a metabolism very efficient at using glucose. The very large protein intake is almost certainly being partly converted to glucose for energy, as well. As you probably know, your glucose stores don't last very long. If they run out, as they would if you begin a fast, your body is used to breaking down protein for it's glucose. It will go right after your muscle tissue to provide this glucose.
If you are eating low carb, your body will become efficient at metabolizing ketones made from the breakdown of fats, and will try to conserve what glucose it has. Low carb diets are muscle sparing. You may need to get your protein intake a bit lower, though - your body may well not make the full conversion to burning ketones, since it can always get some glucose from the excessive protein.
Good to hear the walking is okay, it makes cutting down on cardio easier, just as long as I'm not 'sitting' all day long (work at a desk job at the moment). Aside from lifting I still need to do some sort of movement I find or else I get antsy and just feel lethargic.
That is an interesting point on the protein to glucose. I definitely know a lot of the protein I'm eating will be turning to glucose since I'm far exceeding my requirements. How come though, once the glucose runs out from the carbs the body wouldn't turn to fat stores rather than muscle? Plus, if I was eating in a surplus, shouldn't there be enough stores to last through the fast (and I am only fasting about 11-12 hours per day, so not totally a full on IF set-up).
I am going to reduce my carbs today though, cut out one of the bowls of oatmeal I normally eat before bed. Would it be okay to keep protein around 200 grams (100/meal) or is that still too high? (based on a 2000 calorie diet). Carbs would then be around 100 grams or so and the rest will be fat. Then as I need to add more calories I'll add in more fat to this. The protein I am eating though is very slow digesting (lots of cottage cheese) so maybe that will help things?
