I would hazard a guess that you inadvertently kicked yourself into ketosis. If you've been limiting your total carb intake to under 50g a day, it's possible this happened. There's a ton of good info on ketosis, a couple of great podcasts by Steve Gibson on it, and a good subreddit http://reddit.com/r/keto.
No, I wasn't in ketosis -- my carbs were well over what it would take to go into ketosis.
I was thinking part of it may have been the wheat/yeast throwing my intestinal microbes out of balance (http://www.nytimes.com/2013/03/28/health/studies-focus-on-gu...) and so when I cut it out, things returned to homeostasis.

Have you been tracking calorie intake, both before and after the diet change? That's the deciding factor for your weight. Metabolism, wheat/yeast sensitivity or even normal exercise only has a minor impact.
I would think dropping something as common as wheat would have significant impact on your diet, or?

This isn't entirely true. If you take in the same amount of calories but something changes your metabolism, you can switch from using all the calories and entering a deficit, or storing the calories as fat. This is partly what happens with ketosis. You can eat the same amount of calories overall, but with almost no carbohydrates, and this changes your metabolism. You will lose weight in keto without excercising more if you are so inclined. Like many things, it's a good rule of thumb to say that less calories == less weight, but it's a nuanced situation. That's not always true.
I'm not saying that metabolism has no effect, I'm saying the effect is small relative to calorie intake. I'm well aware of how a keto diet works, and that it can be useful for people looking to lose weight. It's no guarantee, though. There are actually people out there bulking on keto as well.
As for the parent poster, I haven't seen any evidence of calorie tracking. To me that means he doesn't really know how much he's eating, and I think you're just encouraging his flawed metabolism theory when you should know better.

That's really interesting. I've read about intestinal fauna having big impacts on how food is processed.
A simpler explanation is that his new diet contains less calories than the old one. Achieving ketosis by accident is pretty far fetched, even among ignorant people on some crazy food group diet.
Also probably less phytates and antinutrients from wheat. /r/Paleo is your friend too.
Yes, "Wheat Belly" does an excellent job of explaining exactly what modern wheat is and how it's different from the wheat of 10,000, 100 or even 50 years ago.
As for "Superwheat", well, note that 'super' refers to productivity, not to nutrition. Farmers will like the 30% yield increase, however you may not enjoy having "Superwheat" eviscerate your GI tract.

On other news, scientists developed 'super-tomato' - hard as concrete and with the same taste.
I can't wait for scientists to develop tomacco.
"The process required no genetic modification of the crops."
How did they create a new strain of wheat without modifying on the genetics of an existing strain? And given that it states that they cross-bread two strains, how did they prevent the resultant strain from not inheriting modified genes from the mixed parents?

"The scientists used cross-pollination and seed embryo transfer technology to transfer some of the resilience of the ancient ancestor of wheat into modern British varieties."
It's a ritual of appeasement for the idiot anti-GM brigade. The effect is the same, the circumlocution allows them to say "it's natural!"
As a proud member of the idiot brigade, I thank you for working overtime to understand my camp's objections to GM.
I'm ok with breeding. I probably don't even have a problem with transgenetics, but I'd want each effort vetted.
What I oppose, utterly, are two things.
1) GM foods engineered to enable ever greater use of pesticides.
2) GM foods engineered to create their own pesticides.
See, I've got this weird idea: first, do no harm.
Some people call it the precautionary principle. Also known as the Hippocratic Oath popular in the healthcare professions.
Now, I understand that it may not be possible to completely prove any particle thing completely safe. I get that. I'm not a zealot. And some things thought safe today could proof unsafe in the future. Or vice versa. Because science marches on, values change, and context matters.
But here's two things I do know. With absolute certainty. Based on readily available data:
1) The parties pushing GM are bad actors. Repeatedly. Monsanto, ADM, Cargill, etc are only too happy to poison people to make a buck.
2) The parties charged with safe guarding public health and the environment are completely enthrall to megacorps profiting from poisoning us.
These two points are not in dispute.
So while, in principle, further GM efforts may be all well and fine, in an ideal world, we, unfortunately, do not live a libertarian fruit cake free market utopia. And I prefer to judge things as they are, not by what they should be.

In my experience the people who are anti gm also say they won't eat food with chemicals. Basically they are clueless.
I'm sure many people understand this but I'm going to say it anyway:
People who are anti-GM are skeptical about scientists' ability to predict all the consequences of their meddling in living genes and chemical balance of nature components.
The nature had millions of years of coming up with sustainable balance between growth and death.
I hope no one will argue that many of the priorities in our current scientific environment are short term individual benefits, whether it is political, wealth or recognition.
This is the basis of anti-GM folk mistrust, and not inability to detect that everything is chemicals and cross-pollination is a gene modification as well.

A lot of our food is already 'unnatural' due to humankind practicing genetic modification for thousands of years using plant breeding techniques. If we follow the line of reasoning you present we should also stop all medical research because some companies prioritise monetary gain over the welfare of humankind. I wouldn't argue that it needs regulation to ensure it is used responsibly.

Huh?
Huh?
I don't know what your question is.
I think that particular subpopulation thinks gluten is a chemical that should be avoided so it won't make much difference for Weetabix
Yeah! Those idiots trying to get food on their plate that is healthy and without side-effects. What on earth are they thinking?
Do you really find it odd? Nowadays, if you're not a chemist, you have no idea what you're eating. So it is only natural that people react by avoiding everything that is unknown, unfamiliar, or even seems unnatural.
That's perfectly normal behaviour. What IS NOT normal behaviour is sticking your head in the sand when 1 in 2 get cancer.
Who do you think is looking out for your well being? The companies selling you these things?

Here's a hint for you. Natural does not mean healthy and without side effects. When you are eating a lifeform that contains myriads of chemicals in its purely natural makeup, you have no idea what you are eating. (Often, with herbal medicines, this proves to be an issue, and they get yanked off sale for side effects.) Ironically, it is precisely the synthetic chemicals that you can look up on wikipedia. And if you live long enough, immersed in this flow of entirely natural chemicals and radiation, yourself made of complicated and imperfect chemical reactions, you too will get cancer. (Actually, your body is cancering (deliberate verb coinage) all the time, and nearly always its repair mechanisms catch it early and stop it. It's that "nearly" that's the trouble.)
But hey, facts, harder to process than irrational fear of the new, and a crude prescientific search for "purity".

Natural doesn't even mean natural, especially in the US. Europe has a middle ground between natural and artificial flavorings called "nature identical", but in the US these can just be called natural.
Personally, I don't have a problem with this, but most people don't realize it or other things like how that 100% natural, not from concentrate orange juice is really made.
Also, for "organic" fruit and other foods, maybe that matters, but flavorings and other ingredients only have a requirement to be 95%+ organic content. One company I know of sells flavorings that are mostly organic water/alcohol/other diluents, but then the other 5% can be anything and you only need very small amounts of concentrated flavorings which can be anything "nature identical".

That is not a very convincing argument. We have evolved eating other lifeforms. That makes it much more likely that our bodies know how to handle the chemicals in plants and animals than the fancy colourings, preservatives and flavours in processed food.
Would you be confident foraging for food in our "natural" environment?
A great deal of plants, fungi, nuts, and fruits are highly toxic. Even staples like rice and fish have high levels of naturally occurring arsenic and lead; and most table spices are lethal in high quantities.
On top of that, there are countless carcinogens, allergens, pathogenic bacteria and parasites in the food chain.
There is a reason lifespan has been increasing.

No, that's true - natural doesn't mean healthy and without side effects. But it's at least relatively well understood. Perhaps not in exact chemical makeup but we've co-existed with most of what's in a supermarket long enough to know it's probably not going to cut our lifespans in half or anything.
Suddenly people are making extremely rapid changes to food and it's not unreasonable for people to be cautious about it.

Being anti-"GMO" is as ludicrously anti-scientific as saying that evolution is a lie, except that not believing in evolution doesn't affect anyone else, whereas opposing "GMO" food leads to starving children.

No thanks, I have done my homework. And I, unlike you it seems, know that it is not black and white. It's not all good or all bad and only a fool would try to write it off as such.
I know there are side effects when it comes to GMO, I don't need to be a chemist for that. What I also realise is that there really is no shortage of food on this planet, evidenced by the tons and tons that are discarded daily. There is however a logistics problem, but it will not be solved by GMO. Even IF such a thing was possible by creating crops that fare better in extreme climates, these companies who are behind GMO products have absolutely no interest in helping out poor African kids who are unable to pay for what Monsanto & Co have to offer.

I'd never heard of Lynas before. He strikes me as Bjørn Lomborg character.
I think all criticism should be seriously (honestly) addressed. No worldview is above reproach. I'd eagerly watch/read a debate between Lynas and the people he criticizes. In answering his criticisms, it'd help them to refine their arguments.
But before any of that happens, I'd want Lynas to address his apparent conflict of interest.

And what do you call someone who ignores all negative evidence?
I'd be okay with GMO apologists making an intellectually honest argument, listing the pros and cons, arguing that on the balance such and such makes sense.
Basically, the greatest good for the most people.
Alas, that takes some effort. It's easier to mock critics.

GMO have a bad reputation because the most popular strains, Monsanto's glyphosate resistant strains are indeed concerning from a toxicity, ecologic and economic standpoint.
GM is a wonderful technology, with applications not only in agriculture, but also health. Insulin is produced by genetically modified bacterias, and modified white blood cells are now experimentally used to treat cancer.
There are probably other uses, but I'm not aware of them.

Any food, be it natural or manmade, is made up of chemicals. You will need to avoid foods which contain water if you don't want chemicals in your food.

Or just avoid food entirely.

I'm not suggesting there aren't "bad foods" which need to be avoided. The rest is just a strawman.

"Non-hazardous in case of inhalation" ORLY?
Sorry, but here on HN, you can't defend irrationality or people simply being undereducated here. There's simply too large a crowd of people who think that anyone who makes any gut decision is a moron, and they're particularly active on threads like these, and will downvote you into oblivion.
Never mind that you were explicitly talking about the people who simply cannot know better yet try the best they can. They should know better, and if they don't they're morons.

Just explain to them that distilled water is inorganic and watch their brains hurt.
It's not quite the same effect. The ancestor gene has the benefit of having been field tested over time.
If we invent a new gene, the odds are higher that it has visible benefits but hidden downsides.
If we invent a new gene, the odds are higher that it has visible benefits but hidden downsides.
By no stretch of the imagination is a cross 'field-tested'. There is an entire relationship between genes in an organism, all working together, even cooperating between generations to ensure the population survives.
Cross-pollination can produce entirely unfit specimens, or strains that prosper in one clime but fail in another.
This can all have wonderful yield/resistance benefits for farmers. But it has always brought risk too. My father had whole hybrid crops fail when an unsuspected fungus deformed every cob.
Think of genetic modification (yes, even cross-pollination) as an accelerated, guided evolution. Except instead of trying millions of experiments, seed companies sell a dozen each year.
Each stalk in each wild generation is a cross; only a few have to survive to ensure the population survives.
Our vastly reduced commercial genetic diversity puts our food sources at risk. Yet we cannot use plain wild strains in the modern world; half of us would starve.

Is their any reason we cannot bread in genetic diversity? For example, if we cross polinate are artifical strains with wild strains, and then use standard artificial selection for the most high yielding strain, we should return to genetic diversity.
The only way I can see this not working is if the specific changes we made that yield improved output are the same ones that cause problems.
However, my understanding is that this is extremely unlikely, and the likely problem is that in order to get those changes we were only working with a small number of strains, so we lack genetic diversity across the entire genome.
There is still the economic problem that doing this is expensive, yet causes no benefit to anyone in particular. This seems to make it the perfect candidate for the government to step in and do it.

You evolved that idea very well; I could not be so articulate. The free market makes us all locally optimize our own outcome; who will choose possibly sub-optimal seed just to help out the community? A sucker, that's who.
The govt can help; or some other way of marketing variable-genetic seed that makes sense to the farmer. I don't see any other way.

Actually, I'm not sure that it isn't in a farmers own interest to invest in genetically diverse seeds. A farmers lively hood depends on the success of his crops, so diversifying them would make him more resistant to unexpected crop failures.
In this way, we could view diverse seeds as a type of insurance. However if a farmer takes this insurance, even if it is a net positive investment in the long term, he will not be able to sustain himself in the short term.
You typically need large entities (be them public or private) to make this type of long term investment. If it is not innitiated by the government, we might see Monsanto (or other large GM companies) make the investment. Because if one of Monsanto's crops fails catastrophically, they loose alot, however they have the capital to invest in making their crop resistent to mass failure by introducing genetic diversity.
Unfourtuantly companies also tend to focus short term.
If we're lucky, we will see localized mono-culture failures which will incentives all involved to invest in geneticly diverse crops.

I'm not that experienced in the subject, but do we really invent new genes. My understanding is that we take take existing genes from unrelated organisms. This is still substantually different from cross breading, as when we do it, the organisms to not need to be sexually compatible (or sexual), and we may insert them in ways that nature does not.

it's quite simple to be anti-GM today with the grip that Monsanto is trying to grab. Soon we'll hear it's "too big to fail"..
So, a politically correct way of saying genetic modification.
Will it have "supergluten" ? :)
I would be all for a GM strain of wheat that has more lysine in its gluten, making it a complete protein. The lack of complete plant proteins in this modern age of biological hacking is appalling (although I do get that it's because the vegetarian and anti-GM crowds overlap so much).
What do you mean by 'complete protein'. Based on your comment, and a quick Google, I am inferring that you are saying that plants do not produce enough of he Lysine Amino Acid.
Based on wikipedia`ing [1] it, Lysine is produced exlusivly in plants. Based on my own recollection of high school bio, most amino acid production happens in plants, and animals typically get amino acids through eating.

Awesome. More diabetes in less price.
What? What's the causal link between wheat and diabetes?
There is a pretty strong causal link between being overweight and diabetes. There is a strong causal link between over-consumption and being overweight. Wheat just happens to be a common source of very simple carbohydrates (in the American diet).
So while the GP seems to have been made in jest, it's coming from a place of truth.
So while the GP seems to have been made in jest, it's coming from a place of truth.
Now 99% of the world's wheat is the a descendant of this semi-dwarf strain. However, the chemicals used to process wheat today are potent, and the wheat we consume today is not like the wheat people consumed 100 years ago.
Last year I cut out wheat from my diet and dropped ~80 lbs -- I'm back down to 180. At first I thought it was exercise/sprints, and while I have no doubt this helped, I haven't been exercising much the last few months and I'm still dropping. Maybe it's the gluten in the wheat or maybe it's something else, but it definitely wasn't working for me.
While I haven't read it, evidently Dr. William Davis' book "Wheat Belly" explains this in detail (http://www.amazon.com/Wheat-Belly-Lose-Weight-Health/dp/1609...).
