Artificial sweeteners induce glucose intolerance by altering the gut microbiota. Nature, 514(7521), 181–186
saccharin, sucralose, aspartame, and acesulfame-K disrupt the gut microbiome by reducing beneficial bacteria such as Lactobacillus and Bifidobacterium
gut dysbiosis messes with production of short-chain fatty acids, which are critical for healthy lipid and glucose metabolism

our genetics are very stable. we don't produce mutants and evolve into new species rapidly.
if you see a disease like cancer incidence increasing it isn't because of genetics. people frequently say they just got unlucky when they get cancer.
we give ourselves cancer.
cancer grows in metabolic dysfunction. we eat ourselves into cancer. we sit ourselves into cancer. we hide inside the caves of our house into cancer.
for most cancers, unfortunately we only have ourselves to blame and that is incredibly uncomfortable to think about and why we spend so much time and money finding molecular markers for malignancy that get turned on during our times of metabolic dysfunction.
you've probably had your HDL cholesterol measured. your doctor told you higher is better. 60, 70, 80 — good numbers.
here's the problem: HDL cholesterol concentration is a poor proxy for HDL function.
HDL's job is reverse cholesterol transport — pulling cholesterol out of peripheral tissues and delivering it to the liver for excretion. That's the cardioprotective mechanism. But a high HDL-C number doesn't tell you whether your HDL is actually functioning.
Oxidation to apolipoprotein A-I (apo A-I), HDL's main protein, impairs its ability to interact with cholesterol transporters (ABCA1, ABCG1).
Dysfunctional HDL can actually promote atherosclerosis.
the studies bear this out: raising HDL-C with drugs doesn't reduce cardiovascular events. torcetrapib raised HDL-C significantly and increased mortality. niacin raises HDL-C but adds no cardiovascular benefit. because the number went up but the function didn't.
the emerging measurement is cholesterol efflux capacity (CEC) — how well does your HDL actually pull cholesterol out of cells? that predicts cardiovascular risk better than the raw number.
The same thing destroying the body: oxidative stress, chronic inflammation, insulin resistance are the same things impairing HDL function
if your HDL is 70 but you're metabolically inflamed, your HDL number is meaningless. more useful is you pCEC score (predicted cholesterol efflux capacity)

Your cells have an energy sensor called AMPK. When it's active, you burn fuel efficiently. When it's suppressed, you store fat and your liver pumps out glucose.
Uric acid suppresses AMPK. That means elevated uric acid isn't just a byproduct of metabolic disease — it may be driving it.
This is why high fructose corn syrup and fructose added into foods are uniquely damaging. Unlike glucose, which is metabolized in a tightly regulated way, fructose is processed by the liver roughly 10x faster, with no feedback controls slowing it down.
That rapid metabolism burns through ATP so quickly that the leftover byproducts get converted into uric acid. Worse, the uric acid then amplifies fructokinase — the very enzyme that processes fructose — creating a vicious cycle where each dose sensitizes your liver to the next one.
So the chain is: high fructose corn syrup → ATP depletion → uric acid → AMPK suppressed → insulin resistance, fat storage, and excess glucose production.
The problem was never the sugar per se. It's the uric acid it leaves behind.

the hardest thing to do is shatter your own ego
there are countless reports of people not burning at all or very little when cutting seed oils out of their diet. how could this be?
my hypothesis:
Linoleic acid (the main fatty acid in seed oils) is bacteriostatic and bactericidal (deadly) to small intestinal lactobacillus
Lactobacillus johnsonii helps stabilize the skin’s resilience to UV damage
so if disruption of gut flora by excessive pufa and linoleic acid causes a loss of the gut's protective effects on the skin, then seed oils could very well contribute to ease of sunburning

you may feel overwhelmed and just want some peace to sit and come up with something wonderful...but there's a better chance that the stress and chaos is what you need for your good idea to take shape
best way to get that chaos and questioning everyday is to just have some kids. soon you will have more ideas than you have time.


ketosis is a survival mechanism, it is not a physiologically normal way to live for weeks on end.
The only problem with peer review is the fact almost all studies keep their raw data private --the peer reviewers rarely see the data and when the study is published, the data remains private.
there's no need for peer review if every study just publishes raw data -- then anyone can evaluate whenever they want

creatine use for nicotine cessation:
Only have anecdotal evidence to support this in a handful of people who were all hooked on zyn pouches
Smokers had lower concentrations creatine in the medial prefrontal cortex compared to nonsmokers
https://pubmed.ncbi.nlm.nih.gov/33274546/
creatine supplementation increases brain levels
nicotine lowers brain creatine → low brain creatine may impair prefrontal function and self-regulation → creatine supplementation might restore those levels and support cognitive function during withdrawal
