    So I have been back in the gym after sometime, complete story here http://forums.offtopic.com/showthread.php?t=3650332. I havent been really going by the scale, just the mirror, as far as weight loss and muscle tone.

    Im still big and overweight but I feel my diet is lacking protein I need to build muscle. I eat lots of fish, cottage cheese, etc. to get my protein. By my calculations I am getting about 100g a day. "The rule" is to get 1 - 1.5g per lb you weigh. So I have been looking and researching soy protein. It seems to be the best "bang for the buck" and it being low cal can help in my weight loss.

    My prior weightloss was due to cutting the shit out of what I eat. Now I am more athletic than I could ever imagine, so I want to make sure I get my body in the right condition I need it to be for the things I am doing.

    Any help/suggestions?:sadwavey:

    Don't used soy protein. Do a little more research.

    i'm guessing my big concern is to still be able to lose weight while still building muscle.

    I do have chicken in my diet not as much as fish though.

    some people say soy raises estrogen and lowers testosterone. this makes building muscle and losing weight more difficult

    Contrary to popular belief here I for one do not believe that soy protein is going to cause estrogen spikes. That was what everyone said and for a while now (just under a year) a lot of info has been released saying that it's fine.

    I typically use whey, but I do have 4lbs of soy and I use it now and again. My majority of supplemental protein still comes from whey though.

    count soy protein as a carb. it is missing amino acids for synthesis to occur

    Soy is highly regarded because it is one of the ONLY plants that provides a complete protein. It has all the amino acids.

    science is still out on the estrogenic qualities of soy protein, some science says its fine, some say not so much.

    Personally, with all the other sources of protein out there, I'm going to err on the side of caution and leave it out of my diet when possible.

    EDIT: That being said, I won't not eat a food that has soy protein, but I won't actively seek out foods with it either.

    Is it in yet?
    Building muscle while on a calorie deficit isn't the easiest to begin with, i doubt any estrogen changes that might occur will matter.

    http://www.bodybuilding.com/store/soy.html

    "1. What is it and where does it come from?
    Soy protein is a complete protein that ranks right up there with the best in the Protein Digestibility Corrected Amino Acid Score (PDCAAS). Soy protein is generally very low in or free of fat, cholesterol, and lactose. "

    I'll bet there are TONS of vegetarians at that website. STFU moron.

    lol @ using a store site as a source... obviously they will say shit to make your dumbass buy it. use an independent study please

    "The experiments with delayed supplementation of lysine,
    methionine, and tryptophane are concordant in indicating that
    the essential amino acids have to be simultaneously present
    for protein synthesis. These findings show also that incom
    plete amino acid mixtures which by lack of an essential build
    ing stone cannot be used for protein synthesis, are not stored
    in the body but are further metabolized probably in an ir
    reversible manner. These results should be considered when
    amino acid mixtures for therapeutic feeding are prepared or
    administered. The practical consequences of these findings
    will be further investigated.
    This observation, that supplementing incomplete amino acid
    mixtures with the missing amino acid after a certain time
    interval does not promote growth, seems to constitute an
    important argument against the theory of step-by-step syn
    thesis of protein molecules with intermediate formation of
    peptides. These results and those published by Berg and Rose
    ('29) and by Elman ('39), suggest that the formation of pro
    tein molecules is a coordinated tissue function and can be
    accomplished only when all amino acids which take part in
    the formation are present at the same time.
    Two other papers may be cited in support of such a view
    point (Melnick et al., '46; Russell et al., '46). The first named
    by on February 25, 2008 jn.nutrition.org Downloaded from
    DELAYED AMINO ACID SUPPLEMENTATION 109
    authors explain the different biological values of raw and
    processed soy protein by the observation, "that during diges
    tion in vivo the methionine is released earlier from the heat
    processed soy meal than from the raw soy meal ... in the
    case of raw meal, absorption occurs so late in the intestinal
    transit that this amino acid, as well as the incompletely sup
    plemented amino acids, are not efficiently utilized for the
    synthesis of body protein."
