What they do inside the body – and why removing them takes months
(Full English version – publication-ready)
Modern research clearly shows: trans fats are among the most harmful components of industrially processed foods. They do not behave like normal dietary fats – they act like chemical disruptors that interfere with the molecular structure of cells.
Studies confirm that the negative effects of trans fats do not disappear within days, but often persist for 4 to 12 months. Every portion counts.
Trans fats are unsaturated fatty acids whose natural “cis” chemical structure has been artificially converted into the unnatural “trans” configuration during industrial processing.
Research from Harvard, WHO, EFSA and major laboratories shows that trans fats:
Trans fats become part of the cell membrane and can remain there for months – this makes them particularly dangerous for long-term metabolic health.
Their biological half-life is exceptionally long:
| Location in the body | Typical retention time |
|---|---|
| Blood plasma | 2–4 weeks |
| Fat tissue | 4–12 months |
| Cell membranes of muscle & nerve cells | 12–18 months |
➡ The body removes trans fats almost as slowly as it renews its own cells.
Even tiny doses from fast food or margarine significantly prolong the recovery process.
Particularly helpful sources include:
Polyphenols stabilize cell membranes and support the replacement of damaged lipids.
These fats directly compete with trans fats and displace them from cell membranes.
3–5× per week, 40–60 minutes (walking, jogging, cycling, swimming) increases mitochondrial biogenesis and accelerates lipid turnover.
Scientifically shown to:
➝ activates heat shock proteins (HSP), supporting repair and membrane regeneration.
These averages come from EFSA / WHO / USDA data.
Why?
Sugar causes strong insulin spikes, insulin accelerates the absorption and storage of trans fats –
the combination greatly increases inflammation.
One pizza, one donut or one large portion of fries contains enough trans fats for the body to deal with their molecular consequences for 4–8 months.
Trans fats are not “just another food ingredient”. They are a structural metabolic toxin embedded in cell membranes, disrupting mitochondrial function, inflammation pathways and cellular signaling.
Their removal is slow – but possible with consistent nutrition, smart lifestyle strategies and periodic fasting-mimicking protocols.
