Humans can produce all the glucose they need when in nutritional ketosis or starvation ketosis. https://en.wikipedia.org/wiki/Gluconeogenesis

but does that make it the "default energy System"?

My assumption there is that compliance for meds is probably better than compliance for huge lifestyle changes (such as diet). And that most people that the doctor sees in your BILs situation wouldn't stick to a ketogenic diet, and would need to go onto meds at some point in the future anyway. Asi…

> My assumption there is that compliance for meds is probably better than compliance for huge lifestyle changes (such as diet). This is probably true, but I'd like to see statistics. Compliance with med schedules is pretty terrible, too; that's why all of your antibiotics have a label telling you to actually finish your course.

According to the highlights of this 2011 study[0], compliance is around 50% for drugs. I don't know if this is higher or lower than i was expecting to be honest...

>You don't need drugs, expensive treatments, nothing, only a good diet. Moms on facebook keep telling me this but my physician disagree! Do you have an essential oil for this?

I realized that that statement can be misinterpreted. I'm not talking about not using drugs or going to a doctor when it's needed. I'm saying a good diet can prevent a lot of bad stuff and sometimes even reverse things like diabetes.

I fully agree with you, I was being snarky.

Weight loss comes from having a calorie deficit, not from keto. You can gain weight on keto if you eat more calories. You can achieve the same weight loss by just eating fewer total calories, without cutting carbs as well.

This is well understood by now. The issue is that most people aren't actually going to track their calories- they eat when they're hungry. If you adjust your diet- you can satiate your appetite on a lower number of calories. The idea is that meats, vegetables, and fats help you meet your nutritional goals on a fewer amount of calories when compared to carbs- because carbs are empty calories.

> The idea is that meats, vegetables, and fats help you meet your nutritional goals on a fewer amount of calories when compared to carbs- because carbs are empty calories.

A minor correction: carbs are not necessarily empty calories. If you consider only sugary soda, then yes. There’s no one verb either. There are simple carbs, complex carbs, etc. The best kind of carbs are from whole foods (not refined where fiber and other nutrients are removed).

>It takes a LOT of effort and discipline That's the whole point, low-carb takes less effort and discipline for the same result

> low-carb takes less effort and discipline for the same result

For which group of people and what cultural background?

Any advice on diet that tends towards “this works for all or most” is very likely riddled with personal bias.

Keto is the primary energy system. Consider when you don’t eat (fasting) your body goes into Ketosis. In other words it’s the default energy system. You literally have to introduce Specific foods that knock you out of Ketosis...it just so happens now a days those are the primary foods people eat. Foods that spike insulin and knock you out of Ketosis really wouldn’t have been available in a constant supply to keep peo…

Even in the environment of evolutionary adaptedness, prolonged fasting is not the default. If you're going to argue that metabolism under abnormal conditions defines the primary energy system, alcohol must be the primary energy system. It's used at higher priority than either carbs or fats.

Alcohol is an energy source just as much as carbs, fat and protein for sure...but the brain can’t run on alcohol, only ketones and glucose.

Your natural state is ketosis (that makes it the primary fuel source). And we are not talking about “prolonged fasting” or “abnormal conditions”, we are talking about natural states. So if you happen to kick yourself out of ketosis and start running primarily on glucose most people will burn through their glucose stores in just a few hours and their body will crash/shutdown to preserve the remaining glucose for the brain (think of marathon runners “hitting the wall” which doesn’t happen in ketosis, you basically have unlimited fat energy stores and your body will internally produce the limited glucose the brain needs)

> You can achieve the same weight loss by just eating fewer total calories, without cutting carbs as well. Achieve weight loss - yes, achieve the same weight loss - no. If you primarily want to lose fat rather than muscle, your insulin metabolism becomes an important variable.

This is a popular myth. There is simply no evidence to back to this claim. On the other hand there is a lot of evidence that preserving/increasing lean mass (non fat mass) depends only on protein and not fats/carbs. Check this article which summarizes multiple studies in this area - https://www.menshealth.com/health/a25924744/keto-diet-carbs-...

The brain doesn’t only run on glucose it certainly runs on ketones and ketones are much more efficient at crossing the blood brain barrier. Now when the brain is running off ketones it still needs some glucose, but the body accounts for that by being able to produce its own glucose and doesn’t need it from outside sources like carbs or sugar). Ketosis is the default energy System, in that all things being equal when…

> Source?

More interesting, however, is the fact that ketones can provide as much as 70% of the brain's energy needs, more efficiently than glucose. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3219306/

You are ignoring the most important part, humans don’t need outside sources of carbs/sugar (glucose) to power the brain, the body will produce the required glucose internally. So humans can live without carbs/sugar but the same can’t be said without fats.

And no ketosis is not a state of starvation, it’s not clear why you keep saying that, it’s a metabolic state that the body only gets thrown out of when insulin is spiked.

Again it is the default the body only gets knocked out of when introduced to certain foods in certain quantities, which would not have been available pre-ag.

Our bodies are primate bodies. Primates are frugavorian omnivores (get most calories from fruit, and eat very little animal tissue (mostly insects)). Fruit contain mostly carbs: short carbs a.k.a. sugars. We're optimized for eating lots of sugar. Primates have a hard time producing fat from carbs (a process called lipogenesis), just a few calorie% per day. This, combined with the tiny bits of fat in fruits/insects, w…

I was vegetarian for 10 years and tried a beef only diet for my immune problems.

I was told that I would have trouble digesting meat again but to my surprise, it was much easier than usual, and I felt great the whole day (also actually felt full for like 6-8 hours after a meal).

Then gradually reintroducing foods one by one helped me pinpoint the culprits.

“Nonhuman” primates, it says. It’s pretty clear that humans haven’t eaten a primarily fruit based diet in a very long time. It’s likely that moving away from that diet predated changes that made us human.

you could certainly make the argument that most humans haven't a primarily fruit based diet for a while (although evolutionarily it really hasn't been that long) but that doesn't change the fact they are our closest ancestors and the way our bodies are built STILL very much mirror those of primates which means they, in many ways, still work as theirs did. It's not like we have evolved entirely different digestive sys…

Gorillas digestion is based primarily on fermentation of plant fiber, which is why they have a huge gut. Humans have an acidic stomach environment which doesn’t digest fiber at all. A small amount of fermentation happens in the human gut, but it can only produce a few calories a day.

Evolution has changed us considerably in the last couple million years.

We may be closely related genetically to gorillas, but our digestion is probably closer now to a dog’s than a gorilla’s.
