Question: Where should I buy my chicken products? You may have local options. And a good place to look for local options would be eatwild.com. I'm assuming it's still up. That was a great database and probably still is a great database of pasture-raised products of any type. Not just chicken. And then of course, there are the mail order companies that I have exclusive discounts with inside the Masterpass program, most of which sell chicken products. So, White Oak Pastures, North Star Bison who f...

Question: Why would blood glucose go up on a low-carb diet? When you're adapted to low insulin levels with lower GLUT expression, but you want to get glucose into muscle, you're going to need higher blood glucose levels to do it. I think elevated blood glucose is sufficiently known to be pathological that it would be unwise to assume the sort of more generous interpretation of that as a physiological response. I think it would be a much better approach to do what you need to do to get your blood...

Question: Why do thyroid levels drop on a low-carb diet? So insulin and leptin are both positive regulators of thyroid hormone, production, and conversion. And generally I do think there's probably a larger effect from thyroid production than peripheral conversion. I'm not too sure about that, but insulin does directly regulate thyroid. It has TSH-like effects on the thyroid gland. It doesn't replicate all of TSH's effects, but it does replicate a portion of them. So basically, more or less, hav...

Question: Is hydrogen sulfide produced in the gut a bad thing, and what to do about it?I agree that most people that have this problem have some kind of deranged sulfur metabolism, but I don't see why that makes it a physiological adaptation rather than a pathological condition. The correlation is probably a direct result of the predominance of sulfur-metabolizing bacteria in the gut, which is a bad thing that is actually causing the derangement of sulfur metabolism. Well, you could go the antib...

Question: What if low-carb makes me wake up to pee? I would start by looking at your blood sugar. So I do think it's possible that if your blood sugar. Second of all, it's stimulated by salt. So salt at night might help. Third of all, in order to make it you need copper, vitamin C, and zinc. And then, fourth of all, you need, going past that, I also suggest trying to get deeper sleep. You might want to look at the quality of your sleep. So, I do think generally carbs help people get better sleep...

Question: How does someone get arachidonic acid and choline without eggs and liver? So apart from liver and egg yolks, I think that it is very difficult to get enough arachidonic acid from food. Yes, GLA might help, but there's actually arachiodonic acid supplements. And for the vegans out there, I don't know if the production process is strictly vegan, but they are derived from a specific mushroom and you can get them on Amazon. So I think supplementing with arachidonic acid is probably the mos...

Question: Nutritional suggestions for SI joint pain and sulfur sensitivity? So certainly if it's autoimmunity, I'm thinking you might have problems with folate, where you might want to lower folate intake. You might benefit from having more A and D. You might benefit from removing hypothetically pro-inflammatory foods. Magnesium is important. Acid-base balance is important. Citrate is probably helpful. And then on the sulfur issue, molybdenum and manganese are both important for properly dealing...

Question: If it's easier to store fat than to convert carbs to fat, why is it easier to lose weight on low-carb? It's easier to store dietary fat as fat than it is to store dietary carbs. Why is it easier to lose weight on the keto diet than a higher carb diet assuming isocaloric? Well, I think there's an assumption that's not necessarily true there, but the ease with which you store something as fat is not really related to weight loss. So I think that's part of why that is true, or part of why...

Question: Long-term shortness of breath after COVID-19: do I need iron?I don't think there's any evidence that iron fuels COVID-19. And it's pretty clear that the systemic inflammation is driving dysregulation of iron in a way that hurts oxygen delivery. So it's very clear that low oxygen delivery is a major feature of COVID. And I think probably the bulk of that is due to clotting, but also inflammation. And if you look at the CRP levels in COVID, like going up to the hundreds. Normally, you wa...

Question: Are liposomal supplements really superior? I doubt it. So I think the evidence indicates that liposomes don't survive digestion unless they are pegylated, which means that they have polyethylene glycol that's attached to the liposome to protect them from digestion. There are a number of other such modifications that can be made, but I don't think that applies to most liposomal things on the market. So I'm generally very skeptical of the claims that liposomal will offer superior deliver...

Question: Why would I develop shortness of breath on a carnivore diet? That can happen in scurvy. So given that vitamin C is one of the higher-risk nutrients on a carnivore diet, that would be the first thing that I would look at. I'm glad it was short-lived. I think it's possible that there are vitamin C-sparing effects of a carnivore diet, but they take a little while to kick in. So as you transition, you had a temporary scurvy and then you had adaptations that mitigated that. Certainly it cou...

Question: Is it possible to meet all your nutritional needs on a carnivore diet? So the short answer to this question is yes, but the longer answer to this question, as I just went through, is it's quite complicated. I've said it with respect to carnivore diets. I think it's good to look at nutrition, kind of like an economic portfolio. If you are very, very expert, you can know what you're doing in limiting the asset classes you include in your portfolio. So, really know what you're doing. You ...

Question: Why are medium-chain fatty acids ketogenic even in the presence of carbs?It's all about the ratio. We know for a fact that MCT oil is ketogenic even in the presence of pasta, period, end of story. So, the question here is, biochemically, why is it happening? Well, they go into the mitochondria, even in the presence of insulin and a buildup of acetyl CoA over the incoming oxaloacetate. A high acetyl CoA-to-oxaloacetate ratio generates ketones. So the question is that basically this ques...

Question: What measurement of magnesium status is best to use for arrhythmias?I assume by "measure" you mean a measurement of nutritional status, in which case I think you want to look at the serum level. think that if you're trying to fix a problem with the serum level, you probably at some point want to look at the red blood cell level and the urine level. One of the ways that magnesium could impact the arrhythmias would be through influencing other minerals, and so I would not recommend just ...

Question: Is subclinical thiamine deficiency a contributor to many diseases?So in terms of like in terms of subclinical deficiency, is it common, does it exist? It is hard to answer because, as usual, most of the data that's clear is on severe deficiencies, but there are some studies. I wouldn't say that there's a huge body of literature. There are some studies suggesting that even if you take a group of people who have some blood sugar issues and they are not thiamine deficient by classical sta...
