Low-Carb Vegetables – the Best and the Worst

What low-carb vegetables are good? There’s a very simple rule:

  • Vegetables growing above ground are low carb and can be eaten freely.
  • Vegetables growing below ground contain more carbs, so you’ll have to be more careful with them (especially potatoes).

Like any rule it is not perfect, but these veggies are all fairly good, especially the ones to the left:

Above ground

Carbs per 100 grams (3.5 ounces)

Low-carb vegetables

Do you want to learn more about how to know what vegetables to eat, and which to avoid? We’ve made an entire page about it, check it out:

Low-Carb Vegetables – the Best and the Worst


Lettuce Three Times Worse for The Climate Than Bacon


There’s a lot of talk about meat being bad for the climate, due to production of greenhouse gases. But if you compare calorie for calorie it turns out that many vegetables are actually worse.

For example, growing lettuce produces three times more greenhouse gases than the same amount of bacon.

Scientific American: Lettuce Produces More Greenhouse Gas Emissions Than Bacon Does

While the threat of climate change is probably very real, there’s a big misunderstanding around meat. Greenhouse gases, like methane, from flatulence in cows are seen as a big threat. This not only sounds silly, it’s actually not a major problem.

The methane turns into carbon dioxide within 10 years or so in the atmosphere, and then it’s absorbed into the grass that other cows will eat. It’s all part of a cycle. The amount of carbon added to the atmosphere long term? ZERO.

Compare that to burning fossil fuels, like coal or oil. This means digging up stored carbon and adding it to the atmosphere. It will take millions of years to get rid of it. That is carbon we may be stuck with for the duration of civilization. This is the problem.

The solution to the climate problem is burning less fossil fuel. It will probably be possible to replace that soon, mostly with rapidly improving solar panels and batteries and electric vehicles.

The solution to the climate problem is not eating less meat. It’s not even to eat less lettuce. It’s all about not burning fossil fuels.

In Defense of Low Fat – Denise Minger vs. Dr. Fung

The “magic” theory, à la Minger

Is low fat a great idea? Do you have a few hours to spare? Then check out the new & massively long blog post by the always-entertaining, controversy-seeking and brilliant Denise Minger:

In Defense of Low Fat: A Call for Some Evolution of Thought (Part 1)

The post is a longer and more developed version of her 2014 AHS talk Lessons from the Vegans (worth watching, and it will only take you 30 minutes).

The general idea is that while low carb seems to work great for metabolic problems – like obesity and diabetes type 2 – so too can very low-fat plant-based diets sometimes work fine. Why is that? In Minger’s words it’s because of extreme low-fat “magic”, which presumably is another kind of magic than low-carb magic.

Interesting, but not necessarily true.

Dr. Fung’s reply

Enter Dr. Fung, with a much shorter but still interesting post on the controversy:

Dr. Fung: Thoughts on the Kempner Rice Diet [and the Minger post]

In Dr. Fung’s view the extreme low-fat diets (like the <10% fat rice diet) sometimes work well because you really eat the same amount of carbs but avoid everything else (almost no protein and no fat). This is because all reward from eating disappears, due to the extremely monotonous diet – people only eat when they are truly hungry. The rest of the time they are, in effect, fasting.

My comments and criticism

While I tend to agree with Dr. Fung about most things – and his comments here make a lot of sense – there are also interesting points in Minger’s long post. For example, that the “macronutrient swampland” of Western junk food – high carb, high fat – tend to be where we find massive food reward (think chocolate, ice cream or donuts), leading to overeating. It’s clear that whole-food plant-based diets avoid this problem.

I also have some criticism of Minger’s post. For example she spends tons of time attacking the idea that Ancel Keys started the low-fat movement. This feels very misleading. While it’s certainly true that he did not invent low fat, like Minger says, he was still the dominant figure transforming low fat – earlier a theory that not many people cared about – into officially accepted dogma. Quite a feat.

It’s like Dr. Robert Atkins and low carb. Dr. Atkins took a concept that had already been talked about and tested for over a hundred years – low-carb diets for weight loss – and made it famous and known by everyone. That’s why decades later the word Atkins is still synonymous with low carb. While Dr. Atkins did not invent low carb – not even close – he still had an important role to play. Nobody would seriously argue otherwise.

To summarise I find Minger’s post interesting and – as always – entertaining in her unique way. But I can’t help feel that she’s sometimes seeking controversy more than enlightenment. And there’s no magic in that.

The Acid-Alkaline Myth

If you eat meat, will your blood become acidic, leading to osteoporosis and cancer? This is what some people still believe.

However, as humans have been eating meat since about forever, it would be pretty weird if our bodies couldn’t handle it without breaking down!

The big Paleo star Chris Kresser gave a talk on the science behind the Acid-Alkaline theories at the recent Paleo f(x) conference. I did a brief video interview with him about it and you can see all of it above.

Can Giving Up Grains Cause Cancer?

Colin Campbell

Colin Campbell

Could giving up grains cause heart disease and cancer? This is what Colin Campbell claims in his new book The Low-Carb Fraud:

MailOnline: Are low-carb diets BAD for you? Nutrition expert claims giving up grains can lead to heart disease and cancer

Biochemist T Colin Campbell is the author behind the well-known vegan book The China Study and according to him, we should eat a low-fat vegan diet to keep us healthy.

There is a lack of evidence to support Campbell’s ideas. The book The China Study rests on an observational study – uncertain statistics – that doesn’t prove anything. Moreover, it has been demonstrated that the statistical data in the book were cherry-picked to fit the author’s preconceptions. Statistics that pointed strongly in the other direction were not included.

A new review of all relevant similar studies shows that Asians who eat more red meat on the contrary are healthier. They suffer less heart disease and less cancer. Not quite what Campbell managed to cherry pick from his one China study.

There may be good ethical reasons to be a vegan – it’s open for discussion. But those who fear animal foods for health reasons are afraid for no good reason. Continue Reading →


Asian Meat Eaters Are Healthier!

Red meat

Whooops! Asians eating more red meat get LESS cancer and heart disease, according to a new analysis of eight prospective studies.

Sorry T Colin Campbell and every vegan citing from his “China Study” book. Game over?

Dr McDougall in Shocking Vegan Interview


Let me start by saying this: Being a vegan is fine. I find the ethical arguments compelling and I’m impressed by people who manage to avoid animal products for ethical reasons. Also, I believe that most vegan food (supplemented by vitamin B12) is healthier than a standard Western diet.

That said, I was shocked when listening to a new interview with low-fat vegan advocate Dr John McDougall. A couple of days ago he was on Jimmy Moore’s podcast and, really, you have to hear it to believe it:

Can Vegetarian Diets Cause Mental Disorders?

Can vegetarian diets cause mental disorders, such as depression and anxiety? Some people believe so. And a new observational study shows that vegetarians do indeed have an elevated risk of such problems. Whether that’s really cause and effect is, as usual, impossible to know.
