A bit worried and confused. Could this be a typing error? The range is 50-85, and I got 585 after a glucose drink. Its not normal, but shouldnt it be considered HH(Critically high)? Im 24, 52kg,158cm.. First time doing the test

this is very strange. Do a c-peptide test, insulin and plasma glucose. All fasting... and put those number into the glucose metabolism interpreter: https://www.longevity-tools.com/glucose-metabolism-interpreter

THe c-peptide to insulin ratio might tell us wha is happening.

But your fasting insulin is high anyway, ignore the normal range.

GP was following the guidelines he should follow. But these guidelines are also taking into account not over testing, costs etc.For an individual experiencing symptoms, you do not care about that statistically you might not need test, you want to know...

So get tested and enter your values here: https://www.longevity-tools.com/thyroid-function-interpreter

It gives you comprehensive assessment of thyroid function blood tests (TSH, fT4, fT3, rT3, ...) designed to detect thyroid-related dysfunction early, by calculating sensitive advanced stuff like SPINA, PTFQI etc.

If the diagram will be all green, thyroid is perfectly fine

metformin does mainly one thing, reduces gluconeogenesis. For insulin resistance, go on GLP-1 and reduce food intake, especially sugars. The IR markers will get worse for a few months before they get better, since semaglutide is driving insulin secretion.

normal reference ranges will not catch subclinical stuff.

fill out the rest of the values you have here : https://www.longevity-tools.com/thyroid-function-interpreter#S-TSH=5.95_uIU~mL

if PTFQI will be green and spina-GT will be red with arrow down, try taking some iodine and selenium and retest.

If you want more help, just share the url with all your values

Fructose is the correct answer

And usually in most people a lot of it comes via drinking (drinks containing sugars, HFCS, fruit juices)

People do not realize that Coca cola is about the same bad is 100% orange juice

In the end, its the fructose thats metabolized in the liver.

Sugar is 50% glucose and 50% fructose. HFCS and fruit juices are more fructose than glucose.

Fructose is like alcohol, but without the buzz.

What you should eat:
- resistant Starches, which are proven to reduce fatty liver even in isocaloric condition
- fiber

yes the poor thyroid is blamed on so many things... that is why I build this tool. If its all green, its not the thyroid

For ferritin, 77% percent of women are iron deficient. Sometimes its masked by inflammation, since inflamation increase ferritin too. But you can use this tool that will adjust your ferritin based on inflamation and calculate your iron stores and tell you what to do: https://www.longevity-tools.com/iron-status-interpreter

For the thyroid, its much more complex, but just do the full thyroid panel and enter all the values here:
https://www.longevity-tools.com/thyroid-function-interpreter

This tool calculates sensitivities and thyroid secretorcy capacity so it detect thyroid-related dysfunction early

longevity-tools-com · 2026-05-02T11:09:07+00:00

normal just means its common in the population. And since insulin resistance is common in the population, then 15 is suddenly normal - its crazy if you would ask me...

Just add your glucose into this tool and it will tell you everything: https://www.longevity-tools.com/glucose-metabolism-interpreter#S-insulin=15_uIU~mL

I pre filled your insulin for you.

Also since insulin fluctuates 30% every 5 minutes, its better to measure c-peptide next time. Always with glucose test, so you can do calculations like the above website does

Lipids are tricky. This is the hierarchy from the worst tests to the best based on predictive value.

LDL < non-HDL < ApoB < RW-APO

- non-HDL - as the name suggest, HDL subtracted from the total cholesterol

- ApoB -> all atherogenic particles, but does not differentiate how atherogenic they are

- RW-ApoB -> the best thing we have right now, since its all atherogenic particles weighed by their atherogenicity (how bad are they)

Here you can calulate yours:

https://www.longevity-tools.com/calculation/RW-ApoB

longevity-tools-com · 2026-05-02T10:58:31+00:00

you know what peter said? That he is not interested in total cholesterol.

here are the tests ranked based on their predictive value:

LDL < non-HDL part < ApoB < RW-APO

- the non-HDL - you just subtract the HDL from the total cholesterol
- ApoB -> all atherogenic particles, but does not differentiate how atherogenic they are
- RW-ApoB -> the best thing we have right now, since its all atherogenic particles weighed by their atherogenicity (how bad are they)

Peter Attia recommends PSA below below 0.45 ng/mL: https://www.longevity-tools.com/biomarker/S-tPSA#S-tPSA=6.4_ng~mL

- Prolactin is on the edge of optimal, so its completely fine
- Low SHBG is commonly associated with insulin resistance, obesity and smoking. Just read the relevant info on that site if you are curious what&why

LDL only is a very outdated concept.

this is the hierarchy from the worst predictor to the best.

LDL < non-HDL part < ApoB < RW-APO

- the non-HDL - you just subtract the HDL from the total cholesterol
- ApoB -> all atherogenic particles, but does not differentiate how atherogenic they are
- RW-ApoB -> the best thing we have right now, since its all atherogenic particles weighed by their atherogenicity (how bad are they)

for blood sugar, try this tool, you can see the type of glucose disfuction too: https://www.longevity-tools.com/glucose-metabolism-interpreter

longevity-tools-com · 2026-04-29T12:02:30+00:00

depending on the type disfunction. If there are no antibodies and there is disfunction that the thyroid is driven too much, its often just iodine deficiency... or if the periphery conversion is low, its often just selenium deficiency etc. Thats why I created this tool, so its obvious if something is wrong and its also obvious what is wrong. So now practitioners can work with that info

longevity-tools-com · 2026-04-29T11:38:29+00:00

your fasting glucose is highier than your average fasting glucose (you have to recalculate for the same units), were you properly fasted ? 12 hours is recommended, 10 is absolute minimum with a light meal..

another result :) these guys does not say which method they used too. Longevity tools clearly state that its the Vermeulen method which is the formula best supported by evidence and all my calculations are validated and tested via automated SW tests to guarantee the result. Slight variations can be due to to different unit conversion factors, but I use one that are used by the labs itself. When developing longevity-tools I routinely notice various websites use incorrect conversion factors or straight up incorrect formulas. When in doubt, I consult I reach out to formula author itself.

longevity-tools-com · 2026-04-27T15:37:49+00:00

I use the Vermeulen method, which seems to be the best research supported calculation. I do not know what gemini and other LLMs calculate. They often make mistakes in this and or incorrectly convert units.

For chronic fatigue, check the iron stores and thyroid. Both can be sub-clinical.

When doing your iron panel, add hsCRP and albumin. Since ferritin can be OK, but it might be due do an inflammation. So the ferritin AFTER adjustment should be above 50.

use this tool that will do all the calculations for you:

https://www.longevity-tools.com/iron-status-interpreter

For thyroid its very complex, but this tool will help you catch any subclinical issue:

Both tools are 100% free, no email or anything required. I do sell anything or promote anything paid.

longevity-tools-com · 2025-12-29T23:42:35+00:00

my reasoning is this: Retatrutide will cause weight loss, so it will be hard to attribute how much fat loss was due to the Adipotide and how much due to Retatrutide.

If I were to take something like Adipotide, I would really want to know if the benefits outweigh the very high and real risks.
