The idea of a "debate" around CICO is pretty ridiculous, in the sense that the role that thermodynamics plays in metabolism is well-established and agreed on by everyone

What we're actually seeing is a shift in emphasis away from calories in and more towards calories out
What I mean by this is that more and more nutritionists seems to be recognizing the error in the initial premise of the amount of calories eaten being the only significant factor in weight gain/loss

This is obvious in cases like hypothyroidism, etc, where metabolism is impaired
This isn't a new idea or mutually exclusive with CICO, just a shift in emphasis from one side of the equation to the other

I think most everyone would agree that the amount of food you eat matters, but also that lack of exercise, hormone imbalance, etc, can impair weight loss
A lot of this also has to do with diet politics, such as using an exception to CICO as justification for certain diets like keto, veganism, etc

At the end of the day though I have yet to find a single study showing weight loss in a caloric surplus from any of these diets
This study is an excellent example of this, it found that a ketogenic diet did not show increased weight loss over a high carb diet when the two groups were matched for calories and tracked for 12-months…
This is not to say that these diet don't work, but that when calories are matched the advantage they offer is being easier for some to follow

It's well-known that many of the foods in vegan or keto diets are highly satiating, so they make it easier to maintain a caloric deficit
Then even minor initial weight loss can improve hormone balance as a whole, since visceral fat is burned preferentially

This can improve things like insulin resistance via reduction in fat around the pancreas which impairs its function, other organs likely see similar effects
You don't need to follow any particular diet to achieve weight loss, but you can experiment and find what works for you

The basic principles of increase metabolism via balancing hormones, sun exposure, and exercise, and focusing on satiating whole foods, are the most crucial

The idea that free radicals = bad and antioxidants = good is a major oversimplification

When we talk about redox state it's not just about maintaining as little oxidation as possible, but rather keeping an appropriate balance in place between reduction and oxidation

Chemistry 101:

Put simply, oxidation refers to any chemical reaction involving the loss of an electron, when something is oxidized it just means that one of its electrons is transferred to another molecule
Reduction is the inverse of this, a molecule or atom gaining an electron from another molecule or atom

As you can see, it's impossible for reduction to occur without oxidation, and vice versa, hence the shorthand "redox" refers to this category of reactions

I've been digging more into the connections between the "big three" sex hormones (testosterone, estrogen, and progesterone), and glutamatergic disorders like epilepsy
Interestingly, androgens like testosterone and DHT are actually anticonvulsant, which seems counterintuitive since they increase force production

This seems to result from their conversion into the neurosteroids androsterone and 3a-androstenediol which increase GABA sensitivity
Progesterone is also anticonvulsant as a result increased neurosteroid production, most notably allopregnanolone, but to lesser extent other dihydroprogesterone derivatives

If I had a few million $ to allocate towards developing an herb into a medical therapy, conducting clinical trials on it, etc, I would choose bacopa

Specifically, the possible role of bacopa extracts in improving epilepsy long term
I've reviewed hundreds of rodent and human studies on various herbs and the potential benefits of bacopa in epilepsy have always stood out to me as being some of the most promising, yet the relevant human data seems to be totally lacking
When we consider the role that GABA/glutamate imbalances play in nearly every mental illness and neurodegenerative disorder, the potential applications of these herbs is extensive

N-acetylserotonin, the chemical byproduct of serotonin and precursor to melatonin, acts as an agonist of the TrkB receptor (the same receptor that BDNF activates)

This is another interesting pathway by which MAO inhibition may enhance the actions of neurotrophic factors
Increasing serotonin is also known to raise BDNF levels itself via activation of various serotonin receptors, we see this in SSRI's and other serotonergic supplements/drugs

This pathway could replicate a portion of these effects even if serotonin is not increased significantly
Mostly I find this interesting in the context of beta-carboline containing herbs which act as mild reversible MAO inhibitors, like ginseng or polygala

Most herbs with these properties behave well in rodent metrics of increasing neurogenesis

I think I've found the mechanism behind the reports psychedelics reversing anosmia in some cases, I'll post the studies below

There's a strong association in rodent studies between the neurogenesis growth factors NGF and BDNF in creating new olfactory neurons
Psychedelics are known to increase these growth factors to what seems to be a remarkable degree, perhaps even lasting months after exposure

It seems that the elevated level of these growth factors improves healing of this segment of the nervous system
Hypothetically you could use foods and herbs which are also known to increase BDNF and NGF instead if you aren't comfortable or able to use psychedelics

If anyone has tried this I'd love to hear your experience so far

Yep, though it is possible to reverse this

I had a client recently that mentioned he would feel sick for 2-3 days if he ate junk food after just a few months following my dietary framework, when he before used to eat these foods daily
The key is cutting out hyper-palatable processed foods

These include fried foods, processed grains, iron-fortified foods, and foods with a lot of added sugar

For some individuals cutting out (cow) dairy may be necessary as well
Interestingly I've seen kefir have a significant impact on both reversing food sensitivity and helping individuals rebalance after cutting out problem foods

I believe this has something to do with the interaction of probiotics like L. casei with regulatory T cells
