That's the problem I don't always have left overs.

For breakfast I usually eat about 4 eggs scrambled with some kind of meat and spinach.

would it be perfectly normal to eat eggs again for lunch or almost all day? I feel like I may be eating to much eggs?

Cook more at breakfast and dinner. More often than not my lunch is leftover eggs from breakfast with leftover meat from the night before. You don't have to have leftovers just by accident.

Research / Re: Hunting for hippo and horse 1.78 million years ago

Things like this make me even more convinced we may well have been the apex predator even then.

Unless of course hippos were a lot smaller and more even tempered back then.

One that I haven't seen discussed here is this:  evolution is only rapid when the organism is poorly adapted to the environment, such that selection pressure is strong.  If the organism is perfectly adapted, obviously there's no evolutionary pressure to change.  The fact that evolution has been rapid since the invention of agriculture is actually just another form of proof that we're poorly adapted to agriculture.

To argue that we're now well adapted to agricultural foods, they would have to argue that evolution was fast 10,000 years ago, but has slowed down again.  The evidence is against that.  In fact, evolution seems to have become, if anything, even more rapid since the industrial revolution.

In that article Zuk is quoted as saying 10 thousand years is 'plenty of time' for humanity to select out an genetic issue with digesting grains and it might well be if certain conditions were met, but that does not mean that it did indeed happen, and interventional dietary studies show strong evidence that it did not.

The problem with that theory is that we didn't have a gene for problems with digesting grains that could have been selected out; rather, we would have had to have had a preexisting a gene to tolerate digesting grains.  From the continued prevalence of various forms of leaky gut, diabetes, etc., we didn't have such a gene - or more accurately, we didn't have the full suite of genes that would have been required.

Absolutely. I fell into the trap of looking at the question from her angle :(

But we've definitely discussed speed of evolution and evolutionary pressure before, in fact  I mention it just two posts above yours...

I was talking to Mark Sisson via email; he's just ordered the book.  It'll be fun to read his scathing review when he's done.

I think I'll avoid paying for a collection of content stolen from me  ;)

Just email her marlene.zuk@ucr.edu and ask for a copy. If she's used content from this forum, it is the least she could do.

I don't know why there seems to be such a widespread hard on for proving the Paleo diet wrong, despite interventional studies invariably showing an immediate and substantial benefit to health. No reliance needed on evolutionary theories, interventional studies show this way of eating is healthy.

In the article above there seems to be a complete ignorance of the idea of different levels of evolutionary pressure. With the grasshoppers example, the evolutionary pressure to be silent would be very strong, because if one was not silent, one would get eaten, quite possibly before breeding.

The evolutionary pressure to be able to eat grains without causing health issues would not be all that strong as the health problems caused tend to be cumulative, starting off quite mild but increasing as time goes on to be felt in full force later on in life, past the age at which one would usually have had children.

In that article Zuk is quoted as saying 10 thousand years is 'plenty of time' for humanity to select out an genetic issue with digesting grains and it might well be if certain conditions were met, but that does not mean that it did indeed happen, and interventional dietary studies show strong evidence that it did not.

Research / Re: New Euro study attacks red meat
« on: March 09, 2013, 07:40:22 AM »
Actually reading it, the study found that fresh meat was not associated with increased mortality, but processed/fermented meat was.

I did find the full study, will post the link when I can find it again.

HUGE HUGE HUGE issue, is this was done via dietary journals, and yet they decided not to include grain intake in their data.

They had the info, they had to have, but did not include it in their correlations. That is about as bad as science can get.

The idea that someone has come in and selectively quoted certain members without permission then turned it into a book to be sold at profit pisses me off quite a bit.

Diet and nutrition / Re: Am I being too demanding?

Losing a pound every 2 days seems like reasonable weight loss to me. But the best thing you can do is post a detailed day by day food diary, there might be something in there slowing things down.

Not so far as I remember.  If someone had asked offhandedly in a post here if they could quote me, I might have said "sure" without thinking anything of it.

Still if you are quoted you could/should demand a copy(free) to confirm you have been quoted correctly.

I'm assuming that you did not give permission to be quoted in her book? :)

Seems quite a facetious way to write a book, quoting forum posts and 'debunking' them. If she'd like to see how a real science writer goes about their business, she should read Good Calories, Bad Calories.

As to your other question http://www.copyrightaid.co.uk/forum/topic27.htm would seem to suggest that the forum posts are owned by the site owner and of course the original poster, and she has no right to use them with commercial intent without express permission, which is exactly what she is doing if she is selling a book.

That is great to hear!

Thinking back, the  eczema on my hands did get slightly worse when I first started Paleo, then disappeared forever (fingers crossed).

I've also heard from recovering alcoholics that some get very dry cracked skin for a week or so after they quit, then things improve.

The benefits of reduced sodium chloride consumption have long been accepted, but some experts say this should be taken with a grain of, well, salt. Mark Whittaker meets those shaking up accepted medical thought.
Any diabetic with high blood pressure who walks into George Jerums' Melbourne clinic will get the standard advice: if their salt intake is high, they should halve it. This is despite the fact that when Professor Jerums and his former PhD student, Dr Elif Ekinci, studied the salt intake of 638 elderly type-2 diabetics who went through his clinic at Heidelberg's Austin Health, they found that those who ate less salt were significantly more likely to die.
What we found was the people with the lowest sodium intake had the worst cardiovascular outcomes. 

After 10 years, it emerged that for every extra 2.3 grams of sodium (equal to about a teaspoon of salt) in their urine over a day, their risk of dying fell by 28 per cent. Even though those who ate more salt tended to be fatter, fewer died from "all causes" and, contrary to what we've been told about the dangers of salt to the heart, fewer died from heart disease and stroke.

We put salt licks out for the cattle every now and then. They don't last long.
