Doctor in the House – Watch Diabetes Not Being Reversed Using Low Carb on BBC, While LCHF'ers Freak Out.

This post is about Doctor in the House – Watch Diabetes Reversed Using Low Carb on BBC, While Old-School Dietitians Freak Out.
The YouTube videos may be gone, but the image lives on!
Available to view in the UK on iPlayer 'till 19.12.15 at http://www.bbc.co.uk/iplayer/episode/b06q6y95/doctor-in-the-house-episode-1

In Dr. Eenfeldt's blog post, he makes some schoolboy errors.

1. T2DM (type 2 diabetes mellitus) Reversed with LCHF (low-carb, high-fat) diet. Uh, nope!
a) Sandeep's HbA1c fell from 9.0 to 7.0, which is an improvement but by no means a reversal, as Dr. Chatterjee agrees in https://twitter.com/drchatterjeeuk/status/669875378568171520.
b) Sandeep has T2DM, not T1DM. See When the only tool in the box is a hammer...
Sandeep's BG (blood glucose) went down on LCHF, but what about his dyseverything elseaemia? *sound of crickets chirping*

2. Old-school dietitians freak out. Uh, nope!
In BDA alarmed by controversial and potentially dangerous advice in BBC’s ‘Doctor in the House’, Dr. Duane Mellor sounds pretty cool, calm & collected (though I expect that he sustained injuries from all of the eyeball rolling, as he had to refute for the umpteenth time yet another load of LCHF bullshit).

3. He plays the Shill Gambit card.

Oh, the comments! In typical echo-chamber fashion, LCHF commenters praise Eenfeldt's flawed points. I wonder how long my comment will stay up for?

My comments on the programme (c/p'ed from Facebook):-
"6 minutes in. I think that Priti is deficient in Magnesium (Mg), from her stress levels, anxiety, headaches and difficulty in getting to sleep. Blood tests are useless, as they don't correlate with Mg stores. Need CSF (cerebrospinal fluid) test (lumbar puncture - very painful).

12 minutes in. Priti's blood test results normal. Sandeep has hypovitaminosis D, which is a cause of IR (insulin resistance, it's what caused mine). This important fact is not mentioned. unsure emoticon See http://www.ajcn.org/content/79/5/820.full.pdf

16 minutes in. Talked about sugar in foods & drinks but ignored the large amount of cheese that Sandeep ate earlier. Cheese is *very* energy-dense. Sandeep has been in positive Energy Balance for *way* too long.

24 minutes in. Priti's getting sugar cravings in the morning. Lack of Magnesium also causes IR & poor BG regulation. See http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4549665/

29 minutes in. HIIT (high-intensity interval training) for Sandeep is good for increasing his IS, but little use for reducing his VAT (visceral adipose tissue). You can't out-run your fork.

33 minutes in. Walking for Priti to lose weight? You can't out-walk your fork. If 1,000 steps takes 10 minutes and burns an extra 40kcals, then 10,000 steps takes 100 minutes and burns an extra 400kcals = one chocolate bar.

33:47 minutes in. Sareena has had a full-time job working indoors for the last year. Less sun exposure = falling Vitamin D3 level = deteriorating immune system, deteriorating mood & deteriorating IS. See http://nigeepoo.blogspot.co.uk/2008/12/vitamin-d.html

I don't think that I can watch much more of this programme!"

followed by:-
"In conclusion:-
1. Anyone who suffers from chronic anxiety is probably deficient in Mg.

2. Anyone who lives in the UK (United Kingdom :-D) and has coloured skin and/or works indoors is probably deficient in Vitamin D3.

3. ~85% of people who have T2DM have excessive VAT. Asians who were skinny in early adulthood have limited SAT (sub-cutaneous adipose tissue) hyperplasia, resulting in small skin-folds but large bellies. A LCHF diet is not suitable for over-fat people with T2DM. It should be a LCLF diet i.e. a low-calorie diet, to deplete over-full cells. Calories count.

4. You can't out-walk/run your fork.

5. Dr Chatterjee has a strong bias. This is not a good trait for someone who's supposed to be practising Evidence Based Medicine."

It's interesting that Priti is fatter than Sandeep, yet Priti doesn't have T2DM and Sandeep does. Priti was most likely fatter than Sandeep in their respective childhoods, for whatever reasons. Priti had more SAT hyperplasia than Sandeep, so she has more storage capacity for dietary fat than Sandeep does. Priti can gain more SAT, which protects her from developing T2DM. Sandeep can't, so he gains VAT, which has limited storage capacity and is more metabolically-active than SAT.

Cow's milk, Constipation, Ischaemic Heart Disease & Type 1 Diabetes.

Hat-tip to Jamie Scott and https://twitter.com/_Jamie_Scott/status/503383804686262272 , which led to A1 threat to NZ dairy.
From http://en.wikipedia.org/wiki/Milk

There are a few problems with feeding cow's milk to baby humans.

1. It contains bovine beta casein A1. During digestion, this is broken down into a 7-amino acid peptide chain beta-casomorphin7 (BCM7), which appears to cause issues (e.g. increased gut permeability) increasing the RR of diseases like Type 1 Diabetes and Ischaemic Heart Disease. See http://www.ncbi.nlm.nih.gov/pubmed/?term=A1[All%20Fields]%20AND%20%22beta-casein%22[All%20Fields]%20AND%20%22humans%22[MeSH%20Terms]%20AND%20%28hasabstract[text]%20AND%20%22humans%22[MeSH%20Terms]%29 A solution is to use A2 milk, or goat's milk which is apparently naturally A2. See also Further research for consideration in 'the A2 milk case'.


2. It's much higher in protein (4g/100mL) than human breast milk (1.1g/100mL), as baby cows are supposed to grow very rapidly, unlike baby humans. As 80% of the protein in milk is casein, and casein is joined to calcium as calcium caseinate, this increases the calcium intake, and too much calcium relative to magnesium is constipating. A solution is to increase magnesium intake, or dilute 1 part cow's milk with ~3 parts water & add some coconut oil, to get the fat content back up to 4.4g/100mL.

Depression: The similarity between magnesium and ketamine in inducing amnesia for bad memories.

Here's a 2D-skeletal model of the ketamine molecule.
From http://commons.wikimedia.org/wiki/Main_Page

Thanks to Emily Deans for bringing Ketamine, magnesium and major depression – From pharmacology to pathophysiology and back to my attention some time ago, in a Tweet.

"The link to the pathophysiology of depression is not clear. An overlooked connection is the role of magnesium, which acts as physiological NMDA-receptor antagonist:

1. There is overlap between the actions of ketamine with that of high doses of magnesium in animal models, finally leading to synaptic sprouting.

2. Magnesium and ketamine lead to synaptic strengthening, as measured by an increase in slow wave sleep in humans.

3. Pathophysiological mechanisms, which have been identified as risk factors for depression, lead to a reduction of (intracellular) magnesium. These are neuroendocrine changes (increased cortisol and aldosterone) and diabetes mellitus as well as Mg2+ deficiency.

4. Patients with therapy refractory depression appear to have lower CNS Mg2+ levels in comparison to health controls.

5. Experimental Mg2+ depletion leads to depression and anxiety-like behavior in animal models.

6. Ketamine, directly or indirectly via non-NMDA glutamate receptor activation, acts to increase brain Mg2+ levels. Similar effects have been observed with other classes of antidepressants.

7. Depressed patients with low Mg2+ levels tend to be therapy refractory. Accordingly, administration of Mg2+ either alone or in combination with standard antidepressants acts synergistically on depression like behavior in animal models.

I'm wondering whether the amnesia for vivid dreams (if you wake up in the middle of one) is mediated by magnesium, as amnesia is a ketamine-like effect.

Therefore, a deficiency in magnesium may cause bad memories to linger, increasing the risk factor for situational depression.

4g/day of Epsom Salts provides 400mg/day of Magnesium. Dissolve the Epsom Salts in warm water and add the solution to your drinks over a 24 hour period, to maximise absorption & minimise laxation.

Rigid diets & taking loadsa supplements to compensate for them.

I do not believe you want to be doing that!

This post was inspired by a recently-published study by Alan Aragon & Brad Schoenfeld, as bodybuilders are a group of people who often eat a rigid diet (some eat skinless chicken breasts, broccoli & brown rice for several meals each day).

See Nutrient timing revisited: is there a post-exercise anabolic window?
"Collectively, these data indicate an increased potential for dietary flexibility while maintaining the pursuit of optimal timing."

This post is also aimed at people who eat severely restricted diets in the (often mistaken) belief that something's making them ill.

People with type 1 diabetes who struggle to keep their blood glucose within reasonable limits (3 to 8mmol/L, or 24 to 144mg/dL) benefit from restricting their intake of high-GL carbohydrates, so this post is not aimed at them. See The problem with Diabetes.

People with type 2 diabetes who severely restrict their intake of carbohydrates must be in caloric deficit, otherwise the physiological insulin resistance caused by high serum NEFAs will mess up just about everything in their body if they are in caloric balance or caloric excess. I've read (so it could be false) that a certain non-skinny blogger who I'm in conflict with (who has type 2 diabetes and who eats a VLC diet) has heart problems and is taking medication(s) for high blood pressure. Hmmm.

People who suffer from gastrointestinal problems after eating gluten-containing foods, or mucus after eating casein-containing foods may have impaired gut integrity. See Gluten - more than just a pain in the guts?

Supplements that I consider of positive value are:-

Fish oils: If the diet is low in oily fish (tinned tuna is not an oily fish), there may be insufficient EPA & DHA (especially in men, children & post-menopausal women). Women of reproductive age can get away with taking flaxseed oil.

Magnesium: If the diet is low in veg/high in dairy, there may be too much Calcium relative to Magnesium.

Vitamin D3: If the lifestyle results in sun-avoidance, insufficiency in Vitamin D is highly likely.

Vitamin K2: If the diet is low in animal fats and/or fermented foods, insufficiency in Vitamin K2 is highly likely.

Supplements that I consider of negative value are:-

Vitamin A: If there's an insufficiency in Vitamin D, supplementing with Vitamin A/β-carotene may exacerbate it. As Vitamin D + Calcium may reduce cancer risk, supplementing with Vitamin A absent Vitamin D3 may increase cancer risk.

Vitamin E: If there's an insufficiency in γ-tocopherol, supplementing with α-tocopherol may exacerbate it. As γ-tocopherol may reduce CHD mortality risk, supplementing with α-tocopherol absent γ-tocopherol may increase CHD mortality risk. Most Vitamin E supplements contain α-tocopherol only. Some Vitamin E supplements contain mixed tocopherols and these are O.K.

I see stupid people - Part One: Live to take the p*ss.

This is a take on I See Weak People – Part Three: Live to add, not subtract.
Dunning-Kruger strikes again!
George Henderson recently said in a comment to flip:- "If you're one of the sensible ones, as Nigel seems to think you might be, it's easy to see why he won't post on "that" blog again.
Myself, I wonder how Nigel does it. Everywhere he goes he seems to start a fight these days. We are thinking of locking him inside when we go out in future."

How do I do it? Simples! I make sure that my brain is properly nourished with Vitamin D3 for razor-sharp wit & biting sarcasm, EPA & DHA for stable mood and Magnesium to stay cool, calm and collected when all around me are behaving like complete and utter tosspots & twats (UK usages and not meant affectionately!).

Metabolic Inflexibility: What it really means.

Here's a picture from Metabolic Flexibility and Insulin Resistance.

The Metabolically-Inflexible (MI) & Insulin Resistance

Here's another picture.
Fig 2. ● = Metabolically-Flexible (MF). ○ = Metabolically-Inflexible (MI).
Salient points:
1) Excess serum FFA a.k.a. NEFA is bad.
2) Respiratory Quotient (RQ) a.k.a. Respiratory Exchange Ratio (RER) changes due to dietary changes are more sluggish in the MI than in the MF.
3) Under Insulin Clamp conditions, RQ/RER is lower in the MI than in the MF, due to impairment of glucose oxidation and non-oxidative glucose disposal.

I have posted this because of Danny Roddy's post Is Supplemental Magnesium A Surrogate For Thyroid Hormone? , which leads onto A Bioenergetic View of High-Fat Diets.

In the first article, Danny Roddy writes:-
"Additionally, taking magnesium while actively engaging in a diet or lifestyle that reduces the respiratory quotient (e.g., high-fat diet, light deficiency, excessive exercise) seems pretty silly. For example, as a rule, diabetics have a reduced respiratory quotient (Simonson DC, et al. 1988), tend to have higher levels of free fatty acids or NEFA (Kahn SE, 2006), and are often deficient in magnesium (De Valk HW, 1999)."

The second sentence (diabetics have a reduced respiratory quotient...and are often deficient in magnesium) seems to contradict the first sentence (...taking magnesium while actively engaging in a diet or lifestyle that reduces the respiratory quotient seems pretty silly).

Simonson DC, et al. 1988 is Oxidative and non-oxidative glucose metabolism in non-obese type 2 (non-insulin-dependent) diabetic patients.
"In conclusion, during the postabsorptive state and under conditions of euglycaemic hyperinsulinaemia, impairment of glucose oxidation and non-oxidative glucose disposal both contribute to the insulin resistance observed in normal weight Type 2 diabetic patients. Since lipid oxidation was normal in this group of diabetic patients, excessive non-esterified fatty acid oxidation cannot explain the defects in glucose disposal."

Impaired glucose oxidation with normal lipid oxidation lowers RQ/RER. Therefore, lower RQ/RER must be bad, right? Wrong. From the above study:-
"...euglycaemic insulin clamp studies were performed..."
Remember Salient point 3)? Simonson DC, et al. 1988 is an insulin clamp study, the results of which don't apply to free-living people (who aren't insulin clamped).

See also Determinants of the variability in respiratory exchange ratio at rest and during exercise in trained athletes. RER/RQ increases & decreases with increases & decreases in exercise intensity. This is Metabolic Flexibility (MF). Sorry, Danny.

Cancer, part 2.

In cancer, I discussed omega-3 and methylglyoxal.
Methylglyoxal
This time, I'm just going to do a Research Review, by publishing a list of PubMed searches with the following Filters activated: Abstract available, published in the last 10 years, Humans.

Cancer AND "Dichloroacetic Acid".

Cancer AND "Magnesium".

Cancer AND "Methylglyoxal".

Cancer AND "Omega-3".

Cancer AND "Vitamin D3".

Cancer AND "Vitamin K2".

I added searches for Magnesium and Vitamin K2, as I supplement with those and want to see if they have a positive or negative effect on Cancer. I added Dichloroacetic Acid (DCA), as I've read about it.
