Concerning protein, here is one opinion:

Lyle, I follow you up to a point but what are you calling sufficient
protein? US RDA (or DRI or whatever it is these days)? WHO’s
recommendations? Some other amount?
For dieting: 0.8-1 g/lb LBM.
It’s been known for over 30 years that protein requirements go up when
calories go down which makes most of the standard recommendations (RDA,
probably WHO) too low (they are based on maintaining body protein under
normal dietary/non-stressed conditions).
The PSMF studies determiend taht you need 1.5 g/kg LBM (they actually
used ideal bodyweight as a proxy for lean body mass), or about 0.7 g/lb
to limit LBM losses (while still allowing a sufficient caloric deficit).
Of course, that’s in extreme obesity (the more bodyfat you have, the
less proetin you tend to lose). It’s also without activity.
For an active individual who is not extremely fat, .8-1 g/lb LBM would
be the minimum I would consider sufficient.

I would be more inclined to begin a personal evaluation of protein needs from
the perspective of athleticism, right from the start. Because, eventually, if
you read the D’Adamo and make sense of the mental/emotional neuro-physiological
implications of exercise and the type-o situation, you will see the importance
of such a lifestyle option.

**For dieting: 0.8-1 g/lb LBM.**
What is LBM? If it is “lean body mass”, then what does “0.8-1 g/lb LBM” mean?
This post flew right over my head!!
Thanks,

Hey Axel…look at me SnipSnip-ing my posts! Ain’t ya prouda me?
**In this instance the complete mass of your body at the earth’s gravitation
is divided into wither Lean body mass (anything that is not fat) and fat.
So the Lean Body Mass is is all the non-fat substance in your body. So if
you weigh 125 lbs and you are 20% body fat (25 lbs) then you are 80% Lean
Body Mass (100 lbs). In this case you multiply the Lean Body Mass by .8 to
1 gram and this person would want to eat 80 - 100 grams of protein per day
according to this estimate.
Does that help?**
