Re: BMR Confusion

that BMR formula is a general one for folk laying in bed sleeping 24 hrs a day. if you know your lean body mass you can use the Katch McArdel forumla and be more accurate for your build. BMR = 370 + (21.6 X lean mass in kg)

Dr Atkins says that he tells tired folk to eat more foods and they are the only folk he tells to do that. So feed your hunger. since you have been doing Atkins a while you might also want to climb the OWL ladder and add more carbs cause as a vigorous exercisie your ketosis can handle morer carbs. i know when I was lifting and HIITing back in OWl I could easily handle over 100 net carbs a day and still lose.

Re: BMR Confusion

I was thinking to moving to about 40 carbs per day, all extra vegetables but was unsure.

2Big, one more question, what about protein. In the Bodybuilding/powerlifting world, they want me eating at least twice more protein than I am.

Of course since the peoples way of eating is totally different from mine, How should I handle the protien?

Keep it the same? add more since I am following such a heavy routine?

Re: BMR Confusion

the protien issue is going to sound strange but 10% is all the normal human body needs for repair and growth. at 30% we exceed the minimum amount. I know thay are telly you you will be eating your muscles for fuel but that just isn't true unless you are in starvation mode.

glucogenesis will use 3 sources as the building blocks to get to sugar when ATP ( the body energy units) is low and actually it is far more energy efficient for the liver to use the carbon back bone of the fats then the proteins. There should be a chart of all the pathways of glucogenesis here somewhere if it didn't get culled.
there is also a chart of energy production form the same size molecules based on carboins for carbohydrates and fats and we get way more ATP molecules carbon for carbon from fatty acids then carbohydrates or proteins.

the differentce is the fatty acids are not stored as glycogen in muscles with a P attatched to them for an added energy source. And I know you are going to have folk telling you that weightlifting muscles are different then running muscle fibers but there was a study done on training with different diets with actual muscle tissue biopsies done and it showed that even the lifting muscle cells adapted when feed low carb high fat diets to contain more fatty acids stored for fuel and more of the cellular components needed to burn fatty acids as fuel.
Muscles also store excess proteins inside their tissues in what are called free pool amino acids. If you have more protein then they can store the liver will convert them to sugar as the storage mechanism and that will evoke insulin production when the sugars are transported out of the liver in the blood stream.

Since you are cutting you do not want insulin running around burning off those sugars you need the hormone which is in a negative feed back cycle with insulin so fats are being used as fuels. As long as the ATP from the fats remains high in the cells you have fuel and the enzyme that breaks down the proteins remains in its unactiveated state.

One thing to note too is Lyle McDonald the guru of the muscles and the ketogenic plan said in a follow up paper that just 40 grams of carbs ( note that isn't net grams just 40 grams)were needed a day, not before or after working out just during the day, to keep muscle tissue growing and not being canibalized for fuel.

edited to add if you are doing creatine phosphate then you have the phosphogen energy needed for the anerobic part of your workout.
