You'll see it on the page there. The authors advocate a high fat, low carb
diet. They claim that 100g of carbs is about right for most people, with 50
being around right for weight loss and 150 approximately right for weight
gain (pregnancy and muscle gain).

The more people I see reporting their Atkins CCLL and CCLM the more I
think those are the most common values. It also roughly agrees with
Eades. I like the fully custom Atkins approach but that's more work
than most are willing to put in so a median-or-average based system
works well.

Curiously, they are ok with rice & tubers
but not with cereal grains and legumes.

This seems a little arbitrary but not bad. The best known tuber is
potato which is in the nightshade family. The objections to nightshades
parallel the objections to legumes - Not available in paleolithic times.

Poopoo on Veggie oils, too.

There's been discussion of this topic on sci.life-extension recently.

They
are not for overeating protein, either. According to them, anything will
become toxic in the body at large enough dosage.

In the 1980s Scarsdale and other low carb, low fat, high protein diets
ended up problematic by building toxicity from excess protein.
Sometimes a macronutrient of calories, sometimes worse.

They tend to think in
terms of calories from the various macronutrients rather than grams.
Different, but ok.

It still works better than percentages.

PS. I happened to go in a Cracker Barrel this morning. They still have low
carb labeled meals on their menu. I found that surprising!

Cracker Barrel - Where yankees can get country ham. Yum. American
salted proscuitto, sorta-kinda.
