    For the Obsessive compulsive disorder crew.....
    Whether BCAA's like Xtend or EAA like Purple Wraath?

    Andrew? :dunno:

    What about so called non protein amino acids?
    Still the same?

    Not sure why I ever thought otherwise though.

    all amino acids have about 4 calories per gram, though dont think a lot of research has been done on calorie utilization of the non protein amino's.

    here's a question for you...

    what about calorie utilization? if you have 4 calories of protein and 4 of carb does the body get to use all 4 of both types or does it take a bit more energy to convert the protein than carbs?

    I always thought protein supposedly took abit more energy to utilize.
    In for answer.

    The thermic effect of food (TEF) depends on which type of macronutrient you eat. It's basically energy that's used to process it. It's about 20% for protein which is higher than carbs and way higher than fat. TEF accounts for about 10% of our daily energy expenditure. So basically, you'd be wasting 20 cals to process 100 cals worth of protein.

    calorie utilization of certain non protein aminos likely varies because of the way that they are metabolized (since many of them act as specific substrates-particularly if demand is high for those substrates or they are depleted). Some of them also may increase energy utilization and demand by increasing catecholamine levels.

    another instance is beta-alanine, its impact on cellular metabolism and glucose utilization likely offsets any calories that it contributes.

    proteins are still 4 calories per gram and agree that they generally require greater energy output for utilization.

    note- fats are around 7-11 cals per gram (this actually varies a lot- some supersaturates may be as high as 14 cals), but certain fatty acids like DHA can have significant impacts on metabolism. So while they may contribute those cals, their impacts may cause utilization of greater amounts of calories through impacts on PPAR activity.

    So would you include BCAA or EAA in your total protein intake?

    I would think, you could actually consume less protein per day, if you were good about taking bcaa's throughout the day.
