Study Confirms: Excessive Green Tea Consumption (1-2L) May Reduce Your Thyroid Function (T3, T4) by Almost 50%

Written by | published on

If you drink green tea 24/7 you don't have to wonder if your thyroid is sluggish and your belly growing. I've alluded to the anti-thyroid effects of green tea extracts in previous articles. That simply drinking green tea (albeit excessively) would trigger the exact same effects, though, is news. News I got from a very recent study from the  Zagazig University Faculty of Medicine  in Egypt. The authors, Abulfadle K. A., Bakhaat G. A., Shaik R. and Tantry B. A., studied the effect of excessive green tea intake on body weight and serum thyroid hormones in male mice and compared their results to what happens if the rodents are fed only fluoride and caffeine. Overtraining puts you at a similar risk of low thyroid levels as tons of green tea Female Athletes' Body Comp Suf- fers From Dieting Athlete's Triad is not a female exclusive phen.

Thyroid Issues? Low Energy Intake Triggers Low T3 / High rT3 Syndrome in Exercising Women >19kcal/kg LBM Avail. Energy Required. Low Carbing Worsens the Impact of ED

It's not your thyroid, but your behavior that's to blame for your low T3 levels, the fatigue and being "unable to lose weight". If you exercised less and ate more, you could fix it without medical intervention or thyroid madness using Lugol's or other junk ;-) It's something I am facing on a daily basis - on Facebook, in Emails and private messages: Women with self-induced thyroid issue who wonder that their body does everything to conserve lean and fat mass. Women who are working out on a daily basis, dieting like crazy and (in their words) "still not losing weight". It does not take a thyroid expert to identify the reason for their problems: They are training too much and eating too little. Just like the 27 women in seminal experiment that was conducted at the Ohio University in the early 1990s. A study I am going to elaborate on in today's SuppVersity article, although I personally believe it shouldn't take experimental evidence t...

Overtraining, Undereating & Self-Inflicted Hypothyrodism: Thresholds for Low T3 and High Reverse T3 Levels at 8% & 15% Reduced Energy Intake + Exercise After Only 4 Days!

This is not a "woman thing" only and your T3 levels are not the only thing that's going to "fall flat" if you starve yourself through your workouts! Yep, low libido => low total testosterone => low free testosterone => hypogonadism, that's what we are talking about, guys. While I did promise to summarize some of the things, I said about creatine kinase, ALT, AST & Co on the last installment of the SuppVersity Science Round-Up on the Super Human Radio Network (I will do that in a future blogpost), today's SuppVersity article will focus on a single and in my experience often misinterpreted and / or overlooked symptom of overtraining that I personally have encountered numerous times in both male and female trainees: Self-induced hypothyrodism , low T3- or the euthyroid sick syndrome are just a couple of names that have been used in the science and laypress to describe this peculiar result of the way trainees deliberately ruin their metab...

(Mis-)Managing Hypothyroidism: 7% Reduction in Energy Expenditure & Fat Oxidation in Patients on Levothyroxine (T4) Mono Therapy. Plus: Alternative Desiccated Thyroid?

The thyroid is a real diva. You better treat her with utmost care ( learn more ) I guess, ... no, I know that a couple of you have to deal with all sorts of thyroid problems. I know you won't like to hear that, but if you read the SuppVersity Athlete's Triad Series you should know that there is more than just the remote possibility, that food and rest would be everything to "heal" your underactive ductless gland (=thyroid). Good indicators are you train everyday, (1) you eat a high protein, low carb, low to at best medium fat diet with a constant caloric deficit, and (b) your TSH level is low to normal, your free T4 level is low to normal but your free T3 level is sub-par. In consequence you will feel sluggish, look sluggish, train sluggish and won't achieve either your fat loss, performance or muscle building goals. If that's you, there is need for meditation, not medication, for stress management, not pills. In fact, throwing the "inactive"...

Science Round-Up Seconds: Vitamin E Succinate, How It's Extracted from Barley Leaves, Kills Cancer, Ramps up Growth Hormone & Spikes Prolactin. Plus: Testostosterone & Thyroid Hormone Decline Due To Plyometrics & HIIT

Regardless of all the hypocritical hoopla around his persona, Lance Armstrong has always been able to push himself like no one else. No wonder that intense plyometrics were part of his regimen. If the SuppVersity Science Round Up was a meal, I guess you could say that Carl Lanore and I were sort of gluttonous, yesterday ( click here to download the podcast, if you have not already done so). We almost raced from one topic to another and therefore all the good stuff from the list is gone already and I am a bit pressed on time to get some "private life" in, so that I am not psyched about the idea of writing about auxiliary stuff. Against that background and in view of the fact that I felt that the pace of yesterday's show did not really leave enough room for some important details, I will stick to rehashing and expanding on the stories about Vitamin E succcinate and the detrimental effects of beating the crap out of yourself doing plyometrics or crazy HIIT workouts (...

Thyrotoxins: Soy, Hormonal Contraceptives, Gut Bacteria or Simply Inflammation - Ladies (and Gents), You've Got the Choice, Hypothyroidism Lies Just Beyond the Corner.

Image 1: Thyroid for energy para- thyroid for bone metabolism. I don't know about you, but sometimes I get the feeling I am not doing enough for the female readers of this blog. And, while even this blogpost is not exclusively addressed to the ladies, the majority of hypothyroid patients are women. Part of the explanation for this phenomenon can be found in the title of this blogpost, already. Both, soy, as well as hormonal contraceptives are "ladylike" , these days. Accordingly, overcolonization of Bifidobacterium and Lactobacillus , or inflammation is all that remains for "real men" (who obviously do not take synthetic gestagens and probably refrain from consuming soy products) to catch up on their female fellow sufferers. But before I totally confuse you, let's take a look at the most recent scientific results. Still ahead of print is a paper by Claudia Lorenz and colleagues ( Lorenz. 2011 ) in wh...
