Lean bulk macros

Protein .8-1g, fat min .35g, carbs fall where they may. This is per lbs of LBM.

Cheers, h.

I want to gain some muscle but keep my current weight. How do I calculate my macros?

If you bulk, whether lean (meaning a smaller calorie surplus) or not, you're going to gain weight...hence "bulk"

It is LBM. Often one will see 'or mid range of ideal BMI', that is applicable for those overweight who have no idea if their LBM.

As @alexmose is looking at maintaining weight I am surmising a weight within the normal BMI range therefore an estemated LBM would be a better target.

Ie: I weigh 103 lbs and have a BMI of 20. Well within the BMI range. A visual guess would say I am between 21-24% bf.
That gives me a LBM of ~80lbs. I aim for 80-100g of protein a day.

If on the other hand I weighed 175 lbs and had no idea of LBM and hadn't worked out prior to starting my weight loss, a protein goal, mid range BMI, would give me a goal of about 110-115g protein.

Hope that helps.

Exactly. *MOST* people make the simple comment about 1g/lb (or some range...I typically state 0.8g-1.2g/lb) but the correct statement is - as middlehaitch stated - is /lbm (lean body mass).

Lean Body Mass is your "non-fat" weight!

So, to keep the math easy....if I am a 200lb dude and my body fat % is 10% then my LBM is 180lbs [200 lbs body weight minus (200lbs x 0.10 bf% = 20 lbs of body fat)]. Make sense?

Yes yes. So I hang out around 123 pounds. The last time I checked my bf % it was around 24% (it has likely lowered since, but I’m a pessimist so 24% is fine for me). So I want. AT LEAST 93g of protein per day, my fats around 33g, and my carbs....I guess not worry?

That sounds great!

Cheers, h.

By the initial post I took it she was recomping. h.

Yeah that makes sense. I always wondered if I needed to include body fat into it and that answers it. Thanks!

Just to be pedantic: It can be per pound LBM, per pound healthy goal weight, per kg of either . . . with different multiplier number to approximate the right actual total number of grams. And then opinions differ about what's the "right multiplier number".

There are unusual end cases for which it isn't true, but once one does the math, 0.6-0.8g protein per pound of healthy goal weight isn't going to yield a number of grams very far off from 0.8-1g per pound of lean body mass, for quite a range of people. Exactly the same, universally? No. But close enough, mostly.

Then, people disagree about what the right multipliers are (0.6., 0.8, 1.0, 1.2 most common); what the right weight units are (outfits like WHO and USDA have RDAs or whatever they call them that are more like half what you see recommended here or on bodybuilding sites, so the per-pound and per-kg distinctions get confused because those organizations' per kg recommendations are about the same multipliers numerically as others' per-pound multipliers; whether people's LBM estimates or source of estimates are accurate enough or not; . . . and more. It's like a religious war, almost, sometimes.

Personally, for protein I like 0.6-0.8g per pound of healthy goal weight, which is close to equivalent to 0.8-1.0g per pound of LBM for a lot of people, think WHO/USDA are lower than optimal given recent research especially for active people or people losing weight or vegetarian or aging.

But for protein, to avoid the whole weird multiplier argument, maybe try:

https://examine.com/nutrition/protein-intake-calculator/
https://examine.com/guides/protein-intake/

(Which also has pros and cons, but at least it's research-based, with clarity about which research is being used.)

Fats, I like 0.35-0.45g/pound of bodyweight, but keep waffling about whether that's pounds of current weight or goal weight 😆; women more likely better toward the higher end of that, men maybe OK lower, from what I've read.
