    new article by Lyle.

    basically it introduces a new (at least to me) formula - the body can sustain a deficit of 31 calories per pound of fat you have, per day. Any deficit greater than that should, in theory, result in lbm loss.

    good read, at least.

    That formula matches what I have found much more closely. When I used the cosgrove formula it was telling me that I should be cutting at 2400 calories, with that lyle formula I get 1800 calories, which is almost exactly what I have been cutting on (and having good success).

    Very cool read, thanks for posting ;)

    i'm curious to see the reasoning behind all these seemingly random coefficients, do you have anything more detailed on this?

    The value for A is likely to be somewhere around 2000, what is the point of adding 66 to it :confused:

    According the Alwyn Cosgrove formula I should be around 2,571.

    In my personal experience with cutting, there is just too high of calories to be able lose bodyfat consistantly. At that level I am sure I could easily sustain and ever build LBM, but certainly not be cutting fat the way I should be. I have gone as low as 1,600 cal's and found that I was loosing LBM and strength, and at 1,900-2,100 I seem to sustain LBM pretty well and lose body fat at a pretty consistant rate of 1.5lbs per week while still sustaining LBM and strength.

    However, when my cut is over, 2,500 is where I plan to be to sustain my current level (not losing anymore weight, but also not gaining anymore) before I move into a bulk.

    Yep go figure I am losing body fat. weight is the same holding steady at 190-195 starting to see my six back (it's been a long while:bowdown: ). 3200cals work out 6xs a week doing cardio 4xs and weights 6xs. Plus because of work I have to walk 2miles a day in addtion to my work outs.

    So I burn oh around 3000+ cals in day just from working out, work commuting to work.

    Cool. Gotta love research that ends with a formula:




    66 + (6.23 x 225) + (12.7 x 75) - (6.8 x 28) =

    66 + 1401.75 + 952.5 - 190.4 = 2229.85

    2229.85 x 1.4 = 3121.79

    3121.79 x .2 = 624.358

    3121.79 - 624.358 = 2497.432

    rouding to closest 100 = 2500


    That's a doable number.

    just so you know, that formula i posted up is not related to the article in the 1st post.

    i just put it up there as i was looking at it today and it related to the post so thought it would be a good comparison.

    :coolugh:

    Ah - thanks.

    I think me cutting at around 2100 is a bit more efficient...

    i dont think this got enough exposure. there is some interesting new stuff in this article, and instead every gets caught up in plugging their numbers into some completely unrelated formula that has nothing to do with the topic at hand - how big of a deficit can you be in, while not losing muscle mass.

    i realize it's 4 pages of reading :noes: but since this is something that just about everyone is concerned with when dieting, i think it's worth it.

    2123 - I can bulk with that :mamoru:

    lyle's works better for me. I can go as low as 1200 on my cut which is what I've been doing and it's working great.

    no i haven't... $75 is a bit much to me for a workout manual.

    There is an article in the May '06 Men's Fitness by Cosgrove that is an excerpt from the Human Inferno product...

    talks about training, diet, and gives that formula that i posted.
