If you pee gets more yellow in that time period (I think) its indicative of ketosis. If anyone is more knowledgeable than me please chime in.

I.. don't think that's true at all. Ketones in your urine is indicative of ketosis. Smell of alcohol on breath is indicative of ketosis. Urine color is not an indicator for ketosis, it's an indicator for hydration.

You are correct. Urine color is an indicator of hydration. But sugar in your urine will cause your urine to be cloudy and more opaque. I've noticed that when I'm in ketosis that my urine is super transparent (just looking at transparency/opaqueness, not at color).

The title is terrible, it should read ketosis/ketones may prevent, reverse age-related effects within the brain. "Low carb" as the title currently reads does not necessarily result in ketosis and your body/brain running on ketones, which appears to be the scope of this study. There is more to dietary ketosis than low carb, just as an example carnivore or paleo diets are low carb, but those will generally not result i…

Everyone I know who is on a carnivore diet has a high enough fat:protein ratio to stay in ketosis most of/all the time. The value of that seems to be pretty common wisdom among carnivores.

It is possible, I have done it myself eating a lot of eggs and fatty red meat. Also, in my case I was also already in ketosis for an extended period of time, meaning my microbiome and cells were primed for ketosis.

That said I have also done carnivore and also not been in ketosis, which I think is probably the norm for most people on carnivore because the protein/fat ratios aren't right.

The commonality in ketosis carnivore and non-ketosis carnivore is removal of refined sugar/carbs which means no insulin spikes, which means steady levels of energy without crashing.

>Who are the stakeholders in "low carb"? Arguably the meat industry, since most low carb people eat more meat. Yes, vegetarian is possible, but I don't know any vegetarian low carbers, while I know a lot of vegetarians and a lot of low carbers eating bacon for breakfast, lunch and dinner. The meat industry probably has a similarly big lobby as the sugar industry. I've dropped 8Kg in the last half year by going mostly…

As always, the "truth" is a moving target and is going to be highly variable depending on circumstance. You should do what works best for you. If that's practicing vegetarianism, awesome. If that's being mostly a carnivore and eating chicken and bacon every meal, go for it. Somewhere in the middle works too (mostly vegetarian, occasional meat, majority of protein sourced from eggs and whey protein). But refined sugar…

>majority of protein sourced from eggs and whey protein).

Why eggs and not fungus and seeds (including nuts, legume pulses (beans, lentils, peas)? Hell what about gluten.

Because I like cheesy eggs and protein shakes. Again, I don't fault anyone who decides to adhere to a vegan diet.

Sugar, not fat is the killer. Incredible how for decades bad research and the likes of Ancel Keys and Phil Sokolof put the health of millions at risk.

I think this is mistaking correlation for causation. The problem with sugar is that it's often found in highly palatable foods that contain large quantities of fat and calories. If one monitors their caloric intake/outtake such that one is in a deficit or at maintenance not only do negative markers disappear, they improve. (Even on a high sugar diet.)

That's not to say: 'only eat lion candy bars and all is fine.' (One reason is that that would be too hard to adhere to since the volume of food is so low because they're so calorically dense. Low volume, even if calories are high, causes hunger. Another would be the lack of fiber, protein and micronutrients.)

But it does show that it's not sugar that's the problem but rather consistently being in a caloric surplus such that people become severely overweight.

Unfortunately, nutrition has become such a religious topic that it's become hard to have civil, scientific discussions. Instead, we stick to our tribe, demonize those who show flaws in our reasoning, and selectively search for research that aligns with what we already believe.

Noted that the underlying cause for the improvement comes from ketones. This should indicate that intermittent fasting would also show similar results. Low carb diet, keto diet, intermittent fasting, they're all just different ways to switch the fuel source from glucose to ketones.

> This should indicate that intermittent fasting I came to comment the same thing. First an aside that I agree with Peter Attia that IF is a confusing term, and instead Time Restricted Feeding (TRF) should be used. The current thought seems to be that many of the benefits from TRF (ie, skipping breakfast) come from causing the body to start generating ketones.

I'd be cautious if you're doing TRF by skipping breakfast.

>Interestingly, TRF improved weight loss and cardiometabolic endpoints—such as insulin levels, insulin sensitivity, and blood pressure—when participants ate early or in the middle of the day [18,19,41,42,43,44,45], but worsened cardiometabolic health or had null effects when participants ate late in the day [46,47,48].

IIRC subsequent studies have found that digestion interferes with sleep quality, which negates the benefits of TRF.

I was about to ask if intermittent fasting would have the same effects as I get the impression that its a healthier way of getting into ketosis. (When I look, I don't see negative effects associated with IF, and I do with keto diets. The research changes a lot and the conclusions don't seem definitive, but I thought someone on here might have an educated opinion on the matter).

Your body goes into ketosis when it "runs out" of blood-sugar for long enough. It usually takes me 2 - 3 days of staying below 30 net grams (i'm a larger guy, for many people it requires going below 20).

IF can be a part of that, in terms of helping you to control your eating and making the time-period at the end of those 2 - 3 days happen maybe a half-day sooner, but fundamentally it doesn't change carbs are carbs.

Also you might find the relationship almost works the other way. Ketosis makes IF much easier. I haven't eaten breakfast in years. I don't even really consider that an IF regimen as much as like... once you get rid of the habit for a month or two you completely don't miss it and forget why you bothered.

Would a time restricted feeding type of intermittent fasting, with a 16/8 schedule, really result in the production of ketones? I thought that it would take about a day and a half or longer to exhaust carbs and start the switch to ketones. Then it’s only the longer fasts (like 5/2 days) that could help.

I'm no expert, but from my vast knowledge gained through the internet[1], it seems that ketosis starts at around the 12 hour mark. But I think it would depend on how glucose saturated you already are.
