Guest guest Posted January 2, 2010 Report Share Posted January 2, 2010 I guess the old saying: " It's the exception that proves the rule " is right, and I'm the exception. ;-) When I told back in October that I intended to stay on Iodoral while doing my T3 therapy, she said she'd be very interested to know if it worked because she hasn't seen many people for whom that is true. Well, it worked, so she can now add me to the shortlist. I've continued to take a single 12.5 mg tab every morning. No HC or Isocort or Iron supplements either. Nothing but T3, and not all that much required for success. I never took over 75mcg and that was only for a few days. And my ferritin is only 47. Here are the stats from my latest labs: Began 's protocol on November 5, 2009 After ten days, reached 75mcg per day on November 15 -- became hyper, with 99+ temps and sweats, pulse in the 90's -- cycled down to zero in a week and then began again on November 23 using a modified protocol. Modified in this case means I began with 6.25 mcg and added more T3 very slowly, as Val recommends, and also that unlike 's recommendation did not take compounded time-release T3 but Cynomel. BLOOD TEST on Dec 4th: TC and LDL dropped 100 points! Triglycerides dropped from 67 to 42 HDL rose from 88 to 97 A1c dropped a bit to 5.0 APO B/APO a-1 = .56 -- HALF the *lowest* risk for CHD! FT3 = 404 (up from 291) RT3 = 10 (down from 25). Ratio = 40.4!!! (up from 11.64) T4 Total = 3.7 (4.5-12.5) FT4 = 1.0 (1.4-3.8) Sodium = 143 (128-145) Potassium = 4.9 (3.6-5.1) Ferritn = 47 (20-288) Iron = 67 (40-160) I reached a dose of 50mcg on 12/16. My temps reached 98.6 steady two days after that. By 12/25 my temps were 99.9 so I reduced my dose to 37.5 and have been there every since. My temps have been rock solid at 98.6 all day, every day for the last 3 weeks. No hypo symptoms at all, and it's clear from my blood tests, lack of symptoms and high energy that my T3 is reaching my cells. I've lost 2 inches from my waist and abs in this time -- mostly due to the excess cholesterol dump I think, since it binds to fatty acids and is excreted. Even more importantly, I've been doing deep, deep medical research these last two months and believe I have found the cause of my RT3 problem to begin with: Leptin Resistance. My blood test for that revealed that I am severely leptin resistant even though I'm no longer insulin resistant to any degree! I've decided to write about it here in the hopes that it will ring some bells for other members and perhaps help them as well. Leptin is the King of all the hormones. It manages and gives orders to them all, including, tellingly, insulin -- yet it takes orders from no hormones. It reigns supreme. It is created from your adipose fat cells, so the more stored fat you have, the more leptin you will produce. When you begin to eat, your leptin travels up through the bloodstream to the blood-brain barrier, where with the help of a protein gets folded into a three-dimensional shape that lets it slip through a precisely shaped keyhole to reach the hypothalamus. The leptin gives your brain a lot of information that will be used to determine how to *handle* your ingested energy: burn or store. And the brain has many tools at its disposal to make your metabolism do exactly what it wants, from making cells insulin resistant (thus storing more fat) to signaling T4 to stop converting into T3 and start converting to RT3. Or, to conversely, to have it make more T3 and 'turn up the heat' to burn more energy. YOU don't control this. Leptin and your brain does. But leptin does more. It signals the brain about how much energy *this* meal contains versus how much stored fat (the brain only sees 'energy' or 'not energy') you have. If the brain thinks it has sufficient energy it raises another hormone to send the signal for you to stop eating. That's when you get that " Can't eat another bite " feeling and you put down the fork, no matter how delicious the food. Doggy bags were created to deal with this hormone. And how it works is important, because that signal makes glucagon (which controls insulin rise) decrease via a hormone called amylin. And leptin does still more. It acts like an A1c test for fat, telling the brain not only about the meal you're eating now, but about how much energy you've eaten over the last several days. [Which explains why we see weight gains on the scale not the day after a binge, but 72 hours later]. This is the crucial information, because the brain doesn't like to make sudden changes. It gathers the leptin info over the course of a few days and only then decides what hormones to use to either burn off excess energy or RETAIN energy by changing your metabolism via your hormones and liver. Amazingly, leptin was only discovered in 1994! And it set off a true Gold Rush among Big Pharma because of how it was discovered: mice bred to be fat (no matter how little they ate) were discovered to have low levels of this hormone, yet when it was synthesized and injected into the mice, they overcame their fat genes and became skinny. Oh! Big Pharma thought -- the Holy Grail! We'll synthesize leptin, patent it, and have the Mother of all Blockbuster Drugs to sell, one that will reverse obesity with a single pill. They poured millions and millions into R & D, but when the first human trials were done, disaster loomed. Yes, the obese people injected with it did lose weight. For the first two weeks. Then they stopped losing, gained it all back, and put on a bit more for good measure. And this was true for all study subjects. Turns out, when they actually examined fat people, they had four to five times MORE leptin than thin people. WTF??? At this point, all R & D stopped, and some companies sold their leptin divisions. One company -- Amylin -- bought out the biggest, and more about them later. So, by 2000, what researchers knew is that obese people are not only often insulin resistant (which begins in the liver), and not only often thyroid resistant (which begins in the liver), but are almost all leptin resistant -- and in all three cases, the result is the same: the correct hormone is produced, but is blocked from reaching the cells, which in turn means that the correct signaling cannot get through. The actual process for this is that the leptin cannot be folded into the proper shape and thus cannot cross the blood-brain barrier. With little or no leptin reaching it, the brain believes the body is in danger of starvation regardless of actual calories consumed, and takes immediate steps to slow down the metabolism. So you get fat, which creates more pooled leptin and you become ever more leptin resistant. It's a vicious circle because for hormones, the ability to reach the cells with the right signal is everything. This was why, for instance, my cholesterol kept rising until it was sky-high: T3 carries the signal the liver needs to know there is sufficient cholesterol in the blood, but RT3 lacks that signal. As soon as cytomel allowed T3 to once again reach my cells, the correct signal reached the liver, which immediately dumped excess cholesterol out of my body. When leptin doesn't reach the brain, it's much, much worse. What it means, in essence, is that while I see a still-overweight woman when *I* look in the mirror, what my *brain* sees is a very thin woman on the edge of starvation. And it will do everything in its considerable power to conserve as much ingested and stored energy as possible. What this usually means is: 1: During a meal, the leptin that normally would go to the brain saying 'lots of energy here, boss' doesn't get through. So the brain never sends the hormonal system of 'you're full you idiot, so stop eating!' Thus, leptin resistant people are usually always hungry and always eating. 2: In order to conserve as much energy as possible in the easiest to store form (fat), the brain sends out a specific hormone that not only tells us to eat, but to eat lots and lots of carbs, particularly sweets. That's because the brain knows this will ultimately create insulin resistance, which means more triglycerides made in the liver, which means more stored fat. This is why most leptin resistant people say they 'crave' sweets. They do, but only because they are being ordered by the brain to crave them. But what happens when the brain is stored in a body that eats high fat, low carb, and is thus not only satisfied with less food, but with almost no sweets? I'll tell you what happens: the thwarted brain simply pulls another tool from the box for conserving energy: the thyroid hormones. By creating a RT3 imbalance, energy and fat are stored not burned, and the metabolism is slowed to such a state that no amount of exercise, no eating this or not eating that, no calorie reduction will overcome it. In fact, the more you do to lose weight, the more the leptin-deprived brain conserves energy. This finally explains the mystery of how morbidly obese patients can be locked into a hospital metabolic ward, fed 500 calories a day -- and gain weight. Mysterious no more. But what to do about it, that's the question. And for that, someone needed to show exactly how people become leptin resistant (and diabetic, too!). And finally, someone has. In a major study done at Boston Children's Hospital Research Center in 2008 and published in the January 2009 issue of " Cell Metabolism " as: " Endoplasmic Reticulum Stress Plays a Central Role in Development of Leptin Resistance " this mechanism was revealed. From the article: " The endoplasmic reticulum (ER) is a sophisticated luminal network in which protein synthesis, maturation, folding, and transport take place. Perturbation of these processes in several different pathological states creates a condition defined as ER stress and leads to activation of a complex signaling network termed the unfolded protein response (UPR). Previous studies have demonstrated that ER stress and activation of UPR signaling pathways play a dominant role in the development of obesity-induced insulin resistance and type 2 diabetes. Furthermore, reversal of ER stress with chemical chaperones—agents that have the ability to increase ER folding machinery—increases insulin sensitivity and reverses type 2 diabetes in obese mice. SUMMARY Leptin has not evolved as a therapeutic modality for the treatment of obesity due to the prevalence of leptin resistance in a majority of the obese population. Nevertheless, the molecular mechanisms of leptin resistance remain poorly understood. Here, we show that increased endoplasmic reticulum (ER) stress and activation of the unfolded protein response (UPR) in the hypothalamus of obese mice inhibits leptin receptor signaling. The genetic imposition of reduced ER capacity in mice results in severe leptin resistance and leads to a significant augmentation of obesity. Moreover, we show that chemical chaperones, 4-phenyl butyric acid (PBA), and tauroursodeoxycholic acid (TUDCA), which have the ability to decrease ER stress, act as leptin-sensitizing agents. Taken together, our results may provide the basis for a novel treatment of obesity. " To summarize the summary: the study proved that when something/s (still unknown but I believe was right about outside stress, like major surgery in my case, which is when my weight loss stopped after losing 65 pounds but 20 pounds from goal) stresses the ER in the brain, leptin resistance begins. The ER then activates the UPR (unfolded protein response), which means the leptin can no longer get through. And then all metabolic hell ensues. What is stunning about the study though, is that the researchers went further. Once they'd proved the faulty mechanism, they decided to test whether or not sending along a 'chaperone molecule' with the leptin would undo the UPR and let the leptin through. And they not only did it, they did it with two non-toxic drugs already approved by the FDA for treating other diseases! When they gave obese mice a ten-day 'pre-treatment' of 4-PBA the mice didn't lose weight or fat, but once leptin was added to the injections, those mice grew thin and *lean* with lots of lost body fat. And the mice stayed lean. When their hypothalamus' were harvested, it showed that indeed leptin signaling (leptin sensitivity) had been restored. The real eye-opener was with TUDCA though. Just treatment with it alone caused major weight and fat loss. And when leptin was added, just a fraction of the amount used with the 4-PBA was needed for even more drastic weight loss. Which was also stable. TUDCA is biologically identical to UDCA (sold as Actigall in this country), which is used to treat liver diseases. TUDCA was used by the researchers because it's an inject-able liquid, whereas the UDCA is taken orally. Isn't it amazing how everything metabolic somehow leads back to the brain's connection with the liver? And the 'U' in UDCA stands for 'urso' -- Bear in Latin -- because it comes from bear bile. The liver. And it's been used by Native Americans for centuries to treat illness. It is such an incredible substance that there are now clinical trials all over the world using TUDCA to treat Huntington's Disease, Cystic Fibrosis, and Altzheimer's. Researchers believe they are on the verge of major breakthrough's for all three, thanks to this simple substance. So, armed with this knowledge (and the fact that I had diagnosed my own RT3 and Cholesterol problem, and treated them both of them myself successfully), I met with my Endo. I was there for two hours. She did most of the question-asking, and I provided most of the answers. When we were done, she agreed that it was indeed likely that my RT3 problem was originally caused by my leptin resistance, and also with my hypothesis that if I did not treat and cure the original problem (LP), my brain would continue to be leptin-deprived, continue to think I'm skinny, and would only pull another metabolic trick out of its hat to retain my weight and fat. I believe this alone can explain why some people on T3 can lower RT3 and get T3 back into the cells but not lose weight. And why for many, RT3 and/or hypo symptoms return when they return to dessicated thyroid. She agreed to support my being an experiment of one, with help from the Doctor who is leading the UDCA Cystic Fibrosis study at the University of Michigan, whom I contacted and spoke to at length. Starting this week I will begin a 'pre-treatment' of Symlin (pramlintide acetate) injections with the two sample 'pens' my Endo gave me. Symlin is a synthetic form of Amylin, a sister hormone of leptin that plays a huge role in proper insulin use in the body as mentioned above, by signaling the liver to decrease production of glucagon. Type 1 Diabetics no longer make Amylin, and it is either low or missing or not working properly in Type 2's -- which is not surprising given that I believe this is their form of leptin resistance. How it works: " Symlin, by acting as an amylinomimetic agent, has the following effects: 1) modulation of gastric emptying; 2) prevention of the postprandial rise in plasma glucagon; and 3) satiety leading to decreased caloric intake and potential weight loss. " For me, the most important point is reduction of glucagon, which does not work properly in leptin resistant people. Symlin is made by the company Amylin, which was the company I mentioned earlier, that purchased the R & D and rights to patent leptin back in 2000. In fact, Symlin has been shown to cause rapid weight and fat loss in type 1 and type 2 diabetics who take it with their insulin (because I believe based on my research that it too restores leptin signaling; see the Holtof site for more info) -- and the company is currently in trials to convince the FDA to let them market it for weight loss. Followed, no doubt in my mind, by a form of leptin they are working to produce. If my hypothesis is correct, in two months Symlin will fully restore my amylin/leptin connection, after which I will begin supplementing with UDCA/Actigall. I fully expect to have my letpin resistance restored, my T3 problem permanently fixed, and my metabolism completely healed. I also expect to lose the 20 pounds I couldn't before, as well as the 10 I added back when my RT3 began to rise. And I fully expect my insulin sensitivity to grow even better, and my A1c to continue to fall. Knowing now what I know about the brilliance of our intricate hormonal and metabolic systems, and the ability of our brain to rule them *absolutely* despite any of our intentions or actions, I find the advice " To lose weight simply eat less and exercise more " akin to saying " To lose weight bury a chicken bone in the backyard at the full moon and say the following incantation. " Both will be equal in their efficacy. Same thing for " cut out dairy, don't eat grains, count calories, don't count them, eat this, don't eat that, " etc. etc. etc. A person with a perfectly healthy and functioning metabolism will not store excess energy (fat) in the first place. If they feast a day or so they might gain a pound or two, but a week of eating as usual will see that gone without them having to do anything, or eat anything, or not eat anything special. That's how we evolved, and that's how we're still built. Our ancestors never had to 'diet' and neither should we. Abuse or stress my make that metabolism non-functioning, but to cure it requires science, not anecdote or one food over another. My heart aches as I read the same posts over and over on all the various forums dealing with obesity, from calorie-counting forums to low-carb forums. Everywhere is anecdote and useless advice, and science nowhere to be found. I've written this very long post hoping that here at least, with Val and Nick, science will have a place and that their readers will now have a test -- leptin serum level -- to begin, and some solutions to follow. To a Happy and Healthy New Year for us all... Quote Link to comment Share on other sites More sharing options...
