Now I don't have anything against big booties, but when it comes to fitting into your skinny jeans, sometimes a big butt just ain't your friend. What most people don't realize is that before you get that big butt, you've probably developed a broken gut. And I'm not talking about your muffin tops or your waistline fat. I'm talking about what's inside your gut.
Particularly, hormone imbalances in your gut.
So…do you have hormone imbalances?
Maybe you have no clue. That's OK. Let's simply find out with a few more questions…
Do you have trouble falling asleep at night?
Do you spend more time daydreaming about Duck Dynasty than you do focusing on your work?
Do you get sick if anyone sneezes within a one mile radius?
Do you snap when you're stuck in traffic, the internet is slow, or someone smiles wrong at you?
Do you have trouble recovering from that workout you did…a week ago?
If you answered yes to any of those questions, you probably have a bit of hormonal funkiness going on. Today, in this guest post from Dr. Tim Jackson, who is the mastermind behind the “Heal Your Hormones Bootcamp” you're going to learn why (among other things) hormone issues can even cause some serious problems with fat loss, and what you can do about it.
Where Do Hormone Imbalances Come From?
We now live in a world where hormone imbalances run rampant in individuals as young as their early 20’s. While everyone realizes the decline of sex hormones and possibly thyroid hormones as they enter their 40s and 50s, few people understand the ubiquitous nature of endocrine disruption in people as young as 20 and 30 years old.
The decreased sex hormone production that happens in older individuals is well documented and is due in part to decreased output from the ovaries and testes. But what accounts for the relatively recent (within the past 20-30 years) decline in sex and other hormones in increasingly younger populations? The problem is multifaceted and contains several layers.
For one, we are essentially cave men and women walking around with electronic devices: in other words, we are not adequately equipped to deal with the thousands of endocrine-disrupting chemicals like BPAs, BHC, PCBs, etc. that are rampant in our food supply, air, and water. Both external stress (such as relationship or financial stress) and internal stress (like viruses, heavy metals and blood sugar swings) contribute to hormonal disruptions. Dietary contaminants, such as GMOs, antibiotics, and synthetic chemicals, also contribute to hormonal disturbances.
But one lesser-known mechanism behind hormonal imbalances is poor digestive health.
How Your Gut Hormones Break
Let’s unravel this digestion thing because it is severely misunderstood – and you cannot have optimal health or even good hormones without good digestion. Every nutrient in the body must pass through the gut. If any type of malabsorption or dysbiosis exists, all of the cells in the body will become deprived of nutrients needed for basic daily functions, like magnesium, zinc, and all of the B vitamins.
Vitamins, minerals and the component parts of fats, proteins and carbohydrates are needed to make your cells run efficiently, particularly the cells of the thyroid, adrenal glands, testes, ovaries, etc.
So…decreased nutrient levels equals impaired hormone production.
You with me so far?
So, what causes this malabsorption or dysbiosis? Malabsorption can be caused from decreased hydrochloric acid (stomach acid) production, insufficient bile salts, or decreased enzyme levels. Dysbiosis occurs when the ratio of good to bad bacteria in the colon is altered, resulting from antibiotics or over-consumption of carbohydrates.
Both these issues can impact your hormones on several levels.
Consider this: roughly 20% of T4 gets converted to T3 (your active, metabolism-boosting thyroid hormone) by good bacteria in the digestive tract. So if a dysbiosis is present, there is an increased likelihood that some of your T4 will not be converted efficiently into T3. Instead, more reverse T3 will be produced, which binds to T3 receptors but does not induce any of the good actions of T3. What a waste.
Secondly, most toxins in the body are conjugated and excreted with bile via bowel movements. An enzyme known as beta-glucuronidase is elevated in people with dysbiosis. This leads to the de-conjugation of estrogen – meaning estrogen is not excreted with other toxins as nature intended. This allows estrogen to re-circulate throughout the body and wreak havoc.
Excessively elevated estrogen is pro-inflammatory and inhibits mitochondrial respiration, leading to decreased energy production and a decrease in overall tissue function. In addition, as an unpleasant double-whammy, elevated estrogen will prevent T4 from converting to T3.
So now you know…
…Gut dysbiosis and impaired liver health→Elevated estrogen→Increased thyroid binding globulin and decreased T4 to T3 conversion→Decreased free T3→Decreased metabolism…
Heard of Leaky Gut?
Another way poor digestive health impacts hormone levels is via added stress to the Phase I and Phase II liver detox pathways. Your liver uses two distinct phases to metabolize toxins, preparing them for exist out of the body. Phase I involves converting fat-soluble toxins into water-soluble substances, with highly reactive substances being created. These substances then enter Phase II detox, which works on neutralizing those reactive compounds.
Any sort of digestive issue, especially elevated levels of gram-negative bacteria like Pseudomonas Aeruginosa, will slow down the normal mechanisms of liver detox. Gram-negative bacteria have lipopolysaccharides, or LPS, as part of their outer wall. These LPS can be released from the bacteria and irritate the mucosal lining of the digestive tract. If this happens enough, the gut barrier is breached (“leaky gut”) and the LPS reach the bloodstream.
This LPS in the bloodstream creates an inflammatory response system-wide and contributes to decreased thyroid receptor sensitivity. In addition, once the liver absorbs the LPS, they slow down Phase I detox.
This is a big issue, because roughly 60% of T4 gets converted to T3 in the liver. The majority of our other hormones are also metabolized in the liver. If the liver pathways are over-burdened with LPS and toxins from the gut, hormone imbalances are inevitable. In addition, elevated levels of LPS can contribute to insulin resistance and the subsequent downstream hormonal alterations.
So now you know…
…Lipopolysaccharides from gut bacteria→ Impaired liver detox pathways→Hormone imbalances….
Where Pregnenolone Fits In
So far, we have discussed thyroid and estrogen levels. Now, it is time to shift gears and give something called pregnenolone a little love.
Pregnenolone, aka ‘the mother hormone’, serves as the steroid precursor to all of our sex hormones, cortisol and mineral corticoids. During times of both internal and external stress, our bodies will sacrifice the production of our sex hormones in favor of more cortisol.
Remember: you can live without estrogen, testosterone, progesterone, etc., but you cannot live without cortisol because it is critical to your day to day existence!
What constitutes a stressor?
In short, anything that creates inflammation in the body. Inflammatory sources will activate the adrenals to produce cortisol, our natural fire retardant. Gut infections (parasites, bacteria, yeast) all count as stressors to the body that will require the production of cortisol at the expense of the sex hormones. One can supplement with adaptogens, exogenous hormones, etc., but until you uncover the source of the stress, it is analogous to pouring water into a leaky bucket.
So the ultimate goal for optimal health and healthy weight loss is to eradicate any source of inflammation in the body.
To add insult to injury, once cortisol elevates past a certain level, it will contribute to a thinning of the mucosal lining in the digestive tract (making it even more ‘leaky’). This allows the passage of microbes and food particles that normally would remain in the GI tract into the blood stream, creating an inflammatory response and a vicious cycle.
In addition to thinning the gut mucosa, high cortisol levels lower secretory IgA, an important component for maintaining gut health and preventing GI infections. This is one of way in which high cortisol suppresses immune performance.
This is also why people who have completely normal guts can go through a period of stress in their life (e.g. death of a loved one, broken relationship, new stressful job or school, etc.) and suddenly have leaky guts, food allergies, skin problems and all sorts of new mysterious illnesses. It's all cortisol-gut related!
Gut, Thyroid & Sex Hormones Are All Connected
Optimal thyroid function is needed for the formation of the gut-associated lymphoid tissue, abbreviated “GALT”. GALT serves as the one of the body’s storage bins for T cells and B cells, two important types of immune cells. In addition, optimal thyroid levels are needed for the production of hydrochloric acid in the stomach. Without sufficient stomach acid, the entire digestive sequencing is disturbed: the release of bile from the gall bladder is decreased, the production of enzymes from the pancreas is decreased, etc. The altered pH status in the respective areas of the digestive tract impacts the microbiome, increasing the likelihood of a bacterial, fungal or parasitic infection.
In addition, sub-optimal thyroid function decreases both liver and gallbladder function. Testosterone also exerts influence on the microbiome of the GI tract. In rodent studies, increasing testosterone increased the level of good bacteria in the gut, possibly explaining why women are at an increased risk of some auto-immune disorders due to their lower levels of testosterone (in addition to the increasingly and disturbingly large number of the male population who now have plummeting testosterone levels).
Begin By Optimizing Digestion
Whether your goal is to play professional sports, lose a few pounds and shed that big butt, or be fully present for your family and friends, optimizing digestion provides the greatest health return on investment.
Things you can do to optimize digestion include:
–balancing stomach acid, which is commonly low (not high as the media would have you believe)…
-ensuring adequate bile and liver health by eating foods similar to those shown on the below image…
-addressing any bacterial, fungal or parasitic infections found via stool testing (e.g. the “GI Effects Chemistries Profile” panel through DirectLabs)
What About Hormone Replacement Therapy?
With integrative medicine and wellness becoming increasingly accepted, hormone replacement clinics are popping up all over the country. Many of these doctors and practitioners are new to the field and have likely only studied hormones alone and not their interactions with the other body systems. So if you opt for this solution – proceed with caution and try the other fixes first!
Even for those who require hormone replacement therapy, repairing your digestion will help you get the most out of your therapy by reducing inflammation and providing the cellular nutrition needed to deliver those hormones to the correct areas in the body.
Lastly, optimizing the GI tract reduces the risks of side effects from hormone replacement therapy- such as developing fat around the chest for men and the development of facial hair for women – by decreasing the workload on the liver, your body’s hormone processing center.
As you can see, shedding fat is about far more than simply killing time on a treadmill.
It's about fixing bacterial imbalances in your gut.
It's about decreasing stress.
If you want to shed that big butt, you have to first repair your broken gut. And now you know why, along with where to start. Leave your questions, comments and feedback for Dr. Tim Jackson, the Heal Your Hormones Bootcamp or for Ben Greenfield (editor of this post) below, and we promise to answer!
