I'm kinda new to this and am a little unsure of this whole 'macros' thing. How do I determine the % of what my calories should come from for my fitness goals?
Thanks for any help,
Tom

    I would like some knowledge about that too. I have read and seen that protein should be approximately 1 g (some say 0.7-0.8g) of proteine per LBM and fat should be 0.35 g per LBM. Anybody with more knowledge who can confirm or invalidate?

    it all depends on your goals (lose weight, gain weight)

    mine for example are:

    1700 calories
    40% protein (170 g)
    35% carbs (149 g)
    25% fats (47 g)

    I was told to lose weight and have lean muscle mass to stick with 40% carbs,30% fat and 30% protein. Usually if I go over in any category it's protein.

    I'm experimenting with my macro percentages right now-playing around with 2,000-2,100 calories and F50/P25/C25 for percentages.

    I've heard similar to this as well. Set protein and fat based on your body, and then make up the rest with carbs. I have mine set to 40/30/30 carbs/protein/fat. 143g carbs, 48g fat, 107g protein. That's about 1g per pound of my lean body mass for protein, and about .45g fat per pound my lean body mass. The rest is carbs. I've seen good results with these macros, though sometimes I have a problem with going over on carbs.

    I used the Mifflin-St Jeor equation and found that my basal requirements are 709 cal per day, with my activity set at sedentary I get 850 cal per day. Yet I am told not to go under 1200, and when I do the very low calorie, high protein low carb, that is when I lose. I did Jenny Craig and could never get below 142 lbs, and it took me 3 1/2 years to lose the weight (35 lbs).

    This is the equation that I used:
    /Mifflin-St Jeor: Developed in the 1990s and more realistic in todays settings. It still doesn't take into consideration the differences as a consequence of high BF%. Thus, once again, it OVERESTIMATES NEEDS, ESPECIALLY IN THE OVERWEIGHT.
    MEN: BMR = [9.99 x weight (kg)] + [6.25 x height (cm)] - [4.92 x age (years)] + 5
    WOMEN: BMR = [9.99 x weight (kg)] + [6.25 x height (cm)] - [4.92 x age (years)] -161


    And this one supposedly OVERestimates my needs. Something isn't right.

    Pending any medical reasons to eat a particular way, I wouldn't stress it. I would focus on eating clean (i.e. half your plate filled with vegetables, a quarter filled with protein, a quarter with grains or starchy vegetables, and a sprinkling of quality oil).
