Your vagus nerve is the one delivering messages from your gut to your brain.
He's responsible for parasympathetic nervous system activation. He's the one telling your brain that everything is ok, That the gut is digesting and your environment is beneficial. Sympathetic signals usually run thru the spinal chord. In a metabolic view it's quite parallel to oxidative metabolism with high thyroid and Androgens/Progesterone compared to stress metabolism driven by cortisol and serotonin.

Cortisol is making you GREEDY.
35 people were asked donate money inside an fMRI scan with or without a stressor. The higher their cortisol was the lower the donation they made.
49 obese people took 350mg magnesium every day and their cortisol dropped.
4-7 breaths per minute is a great way to stimulate the vagus nerve and activate the parasympathetic nervous…
He SOLVED his adderall addiction with BPC-157.
Too many people abuse amphetamine without addressing the root cause of their ADHD. Adderall doesn't give you dopamine. It BORROWS it. That's why the same dose that used to give you laser focus now barely gets you out of bed. Here's the part almost nobody talks about: your dopamine system isn't broken permanently. It's suppressed, and with the right strategy it can be reversed, full article below.
Another win for magnesium. 46 people with insomnia enrolled in this study.
Daily magnesium increased sleep quality and time while lowering cortisol levels.
If you're doing any form of exercise on a low carb diet, you're basically cortisol-maxxing.
low carb-black lines. high carb-gray lines.
16 overweight women with PCOS were put on ketogenic diet for 12 weeks, this is truly evil in my opinion but…
In this study 2000 IU vitamin D3 was given for 2 weeks to people to test if it lowers cortisol levels,
the results?
The effect of water VS. sugar VS. artificial sweetener on corticosterone levels after training.
75g of table sugar was given to 15 women, cortisol levels were measured, the results?
DHT is a powerful anti cortisol agent, improves sperm production, modulates CRH gene expression.
People with diabetes usually have sleep issues.
In this randomized controlled trial they gave 300 diabetics: 1) placebo. 2)250mg magnesium gluconate. 3)250mg potassium chloride. 4)magnesium and potassium. sleep quality, cortisol and melatonin levels were tested. the results?
They gave people 2000 IU vitamin D3 a day for 14 days to see if it lowers cortisol levels.
the results?
Cortisol causes depression, or at least is elevated in depressed people.
eating more sugar is a potential cure.
One of the main ways Endotoxin activates the HPA-axis is by increasing Nitric Oxide production which directly…
Yet another 2 studies showing low carb diets raise cortisol levels.
They also measured cortisol breakdown products and saw higher rate in the group that ate more carbs, Additionally, this group had higher levels of cortisone the inactive version and lower levels of cortisol compared to the low carb. The authors concluded "A low-carbohydrate diet alters cortisol metabolism independently of weight loss. In obese men, this enhances cortisol regeneration by 11B-HSD1 and reduces cortisol inactivation by A-ring reductases in liver without affecting sc adipose 11B-HSD1. Alterations in cortisol metabolism may be a consequence of macronutrient dietary content and may mediate effects of diet on metabolic health"
Obese young adults divided to 2 groups.
One group ate 310g of carbs, 45g fat,150p Second group ate 50g of carbs,133g fat,100p Guess which group lost more weight, Had Higher levels of T3 and lower Cortisol levels.
Low Carb diets (Less then 35% of the caloric intake) increase cortisol levels, In addition post-exercise…
This meta-analysis reviewed 27 studies with a total of 309 participants and shows a clear link between Carbs and cortisol. If you train regularly, Low carb is NOT a good strategy. If consuming less than 35% of the daily calories from carbs was enough to raise cortisol, Imagine what keto diet would do. PMID: 35254136
Cortisol causes a significant muscle mass loss.
Found to also be catabolic to the Thymus ,Heart, Liver and spleen, basically toxic to every part of our body. Vitamin D3 on the other hand is protective against cortisol, Completely blocked the atrophy of skeletal muscle mass, Thymus ,Heart ,Liver and spleen. dexamethasone (DEX) is a nasty synthetic glucocorticoid, God knows why but it's a standard protocol to be given to patients with inflammation, edema, certain cancers, autoimmune conditions, allergic reactions, asthma and COVD. Although that it was shown in multiple studies to suppress immunity, cause bone loss, atrophy of basically every tissue that contain amino acids. It comes with no surprise because Cortisol main rule is to maintain Blood Glucose levels during stress and it does so by tearing apart every tissue that contains amino-acid e.g., your brain, muscle, thymus etc. The hero of this study was Vitamin D3, We get it Easily from Cholesterol when we expose our skin to the sun, It completely blocked the nasty effects of DEX. "Vitamin D is considered to be a potent anti-catabolic compound [1,2]. Numerous studies suggest a positive role of vitamin D in sarcopenia prevention" Bad news for the Ice bath lovers, this study also showed that ice bath increase cortisol levels, extreme cold is a stressor so it will trigger cortisol. "As was expected, cold water immersion caused a significant induction of hypothalamic–pituitary–adrenal (HPA) axis activation and a cortisol surge into the blood" Main study PMID: 33799389 PMCID: PMC7998166 DOI: 10.3390/nu13030936 1.PMID: 32699341 2.PMID: 30529188 #vitaminD#cortisol#muscle#liverhealth#bioenergetics
The levels of 11b-HSD, The enzyme that converts the inactive Cortisone to the active Cortisol was measured in…
