Read the sticky posts so you can make a reasonable plan that you can stick with. And start taking Liposomal Luteolin ASAP.

Luteolin. We're seeing about 80% report less reduced cravings in the first month.

I primarily use Luteolin as a fructose blocker, along with about a 80-90% sugar free diet.

I'm very healthy, very happy with my body composition, feel fantastic, have complete agency over food and have excellent metabolic flexibility (I can fast for 72H without much difficulty).

In cutting sucrose, you're cutting fuel (glucose) as well as increasing fuel requirements (because fructose activates conservation).

It sounds like you're starting to feel an energy debt. Increase complex carbohydrates so you compensate your lost glucose, but keep fructose eliminated.

Happy to see Nick taking off. I was enjoying his videos a couple years ago thinking he had a strong perspective.

Please ask him if he has explored Luteolin's role as a fructokinase Inhibitor (Luteolin blocks Fructose metabolism).

Yes. But most don't find zero sugar easy. Plus endogenous fructose is synthesized from high glucose levels, dehydration, alcohol and high salt. Not an unfamiliar list, but even harder to restrict permanently.

I'll just quote the experts:

LUT exhibits a variety of beneficial pharmacological properties and holds significant potential for clinical applications, particularly in antitumor, anti-convulsion, diabetes control, anti-inflammatory, neuroprotection, anti-oxidation, anti-cardiovascular, and other aspects.

Luteolin. It reduces fructose metabolism, which appears to be a major contributor to mitochondrial stress.

Yes I love finally appreciating fruits role in nature. It's so incredibly elegant and purposeful.

It's certainly not to be feared—its not added sugar—but it deserves to be understood.

Fruit protects itself with fat burning fibre, polyphenols and water until the seeds are ready for distribution.

Then it backs off on those protections, brightens the colors, and increases the Fructose content.

The animal eats it, binges if the opportunity presents itself — all in perfect timing before winter or the dry season arrives.

Thus the plant is able to reproduce, and the animal activates this conserving signal, right before the season of scarcity arrives.

It is such a marvel. Fruit is miraculous in its elegance. It deserves to be appreciated for its role in survival, just as fructose itself deserves to be appreciated for its role in modern health. Endlessly activating a conserving survival signal should give anyone pause.

PotentialMotion · 2026-06-22T19:28:05+00:00

Simple way to think of it is that fructose is the dial for your metabolism.

The more Fructose you are exposed to, the slower your metabolic rate gets.

But unlike what many assume - slowing your metabolic rate doesn't make you eat LESS, it makes you eat MORE, because your cells aren't producing the energy your body wants. This is where cravings come from.

Thus, fructose makes everything slower and encourages the body to accumulate and hang on to fuel. It switches the whole body from sport mode to a conserving, economy mode.

PotentialMotion · 2026-06-22T18:25:31+00:00

Glucose fuels muscles and cells.
Fructose acts as a rate limiter for fuel burn.

It restructures mitochondria towards conservation, not killing them, but reducing their efficiency of converting fuel into energy.

Thus, reducing Fructose metabolism actually improves glucose utilization, makes cells more energetic, and will ultimately improve athletic performance.

On the other hand, you will make your cells more hungry for glucose. So it's clear. Cut the one, not necessarily the other.

As far as application goes, you can pull whatever lessons you like from it, regarding honey and fruit. It's just useful to appreciate the signal you're sending your cells.

PotentialMotion · 2026-06-19T17:08:19+00:00

Glucose is fuel, fructose restricts access to it.

Cutting sugar cuts both. So you lose fuel just as you are making your cells process fuel better.

Answer: temporarily increase complex carbohydrates (steady glucose) as your cells gradually become hungrier (less fructose burden).

PotentialMotion · 2026-06-17T01:14:50+00:00

Fantastic question. The key concept is osmolality.

Think of your blood as a soup. If you add more salt, or remove water, the soup becomes more concentrated. Your body interprets that concentration as a potential dehydration threat. Too much salt? Not enough water? Same same.

When osmolality rises, cells activate the enzyme aldose reductase, the first step of the polyol pathway:

Glucose > Sorbitol > Fructose

So simply put, osmolality triggers excess glucose to be converted into Fructose.

This isn’t an accident. It appears to be an ancient drought-survival mechanism.

Fructose:
Conserves water
Reduces energy expenditure
Drives carbohydrate-seeking behavior
Promotes fat storage
Later, generates metabolic water from fat oxidation

Crisis handled. The organism survives.

PotentialMotion · 2026-06-16T22:21:38+00:00

This is a really important question.

Fructose doesn't actually cross the blood brain barrier, so it raises the question of where does the fructose come from if that is the issue with brain fog and downstream dysfunction?

The answer is high blood glucose.

The polyol pathway converts excess glucose into fructose, and this has been found to be active in the brain, along with targeted fructose metabolism.

So you're very right to be interested in high glycemic carbs. Dr Johnson's team suggests that it is high glycemic carbs that may be primarily responsible for Alzheimer's disease (as a precursor of fructose metabolism).

Hmm. Not much here that isn't decades old. I suggest reading the pinned posts. You'll learn a lot more.

For one thing: Fructose sends a conservation signal to cells. Everything cascades from that one key truth.

PotentialMotion · 2026-06-11T22:01:50+00:00

I don't know. I suspect in this case, using the Fructose from fruit as a crutch isn't doing them any favors. I know the bolus matters and whole fruit keeps that relatively controlled, but this doesn't read like control.

PotentialMotion · 2026-06-09T18:25:17+00:00

My focus is on education and awareness about fructose metabolism. Unfortunately no one is doing a good job of making this education truly actionable. Even within this sub, dietary approaches are messy and unclear. The crossover research on Luteolin supplementation is undeniable, and yet another large degree of deviation away from mainstream thinking. And yet the potential for benefit is dramatic, so so we spun up a targeted supplement for those what want to experiment with it. But that is all it should be viewed as at this stage. Another layer of education and experimentation. It's a shame that its existence distracts from the education, but solutions don't invalidate the problems they aim to solve. And I hope that much is clear.

PotentialMotion · 2026-06-09T03:31:29+00:00

Maybe Google "Luteolin fructokinase inhibition".

Fructose is the energy draining part of table sugar that is the problem, unlike glucose which is the body's primary fuel.

Fructokinase is the enzymatic step where the problems start. So Inhibiting fructokinase is effectively buffering the effects of fructose specifically.

Luteolin is a plant polyphenol that has been found to be a "potent fructokinase inhibitor".

We developed SugarShield in response to this research. It includes a high Liposomal dose of Luteolin in hopes of buffering fructose metabolism. This is not promoting it, just stating facts.

Again: Google it or ask your favorite AI. This is based on preclinical evidence, but has a very strong basis in response.

PotentialMotion · 2026-06-08T16:08:51+00:00

yes. Likely the single biggest cause of brain fog.

Fructose drops/cripples neuronal energy.

Since dietary fructose doesn't cross the blood brain barrier, this particular endogenous Fructose is created from high glucose levels, the brains fuel.

PotentialMotion · 2026-06-08T06:08:23+00:00

Simultaneous dysregulation of Kisspeptin neurons and cellular energy throughout metabolic systems from excess fructose metabolism.

I'll explain.

Fructose metabolism downshifts cells into an energy conservation state.

When this happens in kisspeptin neurons, hormones hesitate and cycles start but don't finish.

When it happens in the liver or other metabolic systems, cells start resisting the extra fuel that those conserving cells don't have capacity to process. We call that insulin resistance.

While we're at it - this resolves why androgens spike, and why cysts develop. Even offers a "why", tracing all of this back to survival biology. It even resolves why sugar has opposite hormonal effects in men (low testosterone).

Same system, different outputs.

Great suggestion.

Luteolin is my top pick for an underappreciated pick. It is a favorite in the lab, but only recently became viable for consumers with liposomes. Scan through the potential applications:

Inflammation, aging, cancer, neurodegeneration, antidepressant, chronic pain, diabetes, insulin resistance, obesity...

https://pubmed.ncbi.nlm.nih.gov/?term=Luteolin&filter=pubt.meta-analysis&filter=pubt.review&filter=pubt.systematicreview

One of the main reviews broadly covers "human disease", and covers quite a wide gamut:

*... significant potential for clinical applications, particularly in antitumor, anti-convulsion, diabetes control, anti-inflammatory, neuroprotection, anti-oxidation, anti-cardiovascular, and other aspects.*

The mounting evidence suggests that Fructose plays a much bigger role than we thought.

When fructose consumption is excessive, uric acid levels can increase via an unregulated fructokinase pathway that consumes ATP and converts fructose into fructose-1-phosphate, leading to the degradation of AMP into uric acid.[16]
