body's preferred source of fuel

[110%]

i always thought the body's preferred macronutrient for energy was fat, then carbs, then protein, but i saw soemone say carbs was a coupld thread downs. so what is the answer, just lookin for knowledge here?

Carbs, then Protien, then Fat I believe.

when muscles are a rest they use FFA's. during exercise mainly glycogen. depending on diet and type of exercise the ratios of each can be changed. there is always some slight energy derieved from stored proteins (LBM). that expenditure can be increased as well from high cortisol levels ,resulting from high volume training and very high intensity cardio...

Ditto to LAM.

Hey doesn't our body convert any macronutrient into glucose anyway? So I guess the prefered source would be simple sugars, cause they need the least processing?

It all depends if your trying to lose weight or gain weight

I think that I run best on fat from meat. I buy the cheap grund beef and use the Foreman's grill and eat meat and fatfilled cheese most of the time and I get a lot of energy. If I eat the same amount of cals in bread or carbs I get fat and tired. I dont eat meat exclusively though I have carbs sometimes and it works well. But mostly meat. I think thats how people were made to eat-meat with occasional carbs like apples and oranges.

It depends what and how much you eat...the bodies preferred source of fuel is glucose. In fact the brain and red blood cells can not use fatty acids for fuel. But the brain can use ketones.

CytoMel is absolutely right and everyone could benefit from living on mainly meat. Fat is our preffered fuel for most activities and provides 90% of our energy at rest.

Actually I believe alcohol is the preferred source LOL. Your body will burn alcohol calories before any other calories can be used.

In animal studies we use the word 'preferred' to mean whatever the animal will eat first, or in preference to other foods that are offered at the same time. Using this criteria, glucose is unquestionably the preferred fuel in humans (after alcohol) whether they are in ketosis or not, and whether they are underfed or overfed. Your body MUST deal with blood glucose in a timely and efficient manner or else you will be very ill/dead. All other macronutrients can wait to be dealt with to a certain extent.

for a simple answer, carbs/fats/protein in that order.

Thanks and I like diet posts and agree with almost all of your diet plan too.

I differ a tad in that I like a small amount of occasional carbs- 100 grams or so after training and occasionally I like to drink and party. Then I get right back on the meat wagon.

PwB could you give me your source for this 90% number.
