"In 6 weeks, lose liver fat and boost your metabolism!"—granted, that sounds like we're trying to sell you an overpriced detox cure from a pyramid scheme. But don't worry—in this article, we simply want to share a genuinely fascinating study ;) And it actually showed exactly that!
Previously known by the acronym NAFLD (Non-Alcoholic Fatty Liver Disease), since 2023 it's been designated in medical circles as MASLD (Metabolic Dysfunction-associated Steatotic Liver Disease): good old fatty liver disease. Caused not, as the old name suggested, by excessive alcohol consumption, but rather by metabolic dysfunction, as the new name MASLD clearly indicates.
Fatty liver is diagnosed when more than 5% of liver cells have accumulated excess fat. This now affects a significant portion of the population—and Switzerland is no exception, with many people affected by MASLD and numbers rising. Even children are not spared from fatty liver disease today. More and more children and adolescents struggle with overweight, and about a third of them already have fatty liver disease (Source). Yet MASLD is largely preventable or manageable through lifestyle factors like diet and exercise. With the right interventions, most cases could be prevented or at least improved and even reversed.
According to Professor Schuppan and his team, quite a lot! They've been researching celiac disease as well as liver and small intestine disorders for years.
A new clinical study by Schuppan and colleagues from 2024 examined the effects of short-term gluten-free diet on metabolic dysfunction-associated fatty liver disease (Source). However, it wasn't primarily about eliminating gluten, but rather about reducing ATIs (Amylase-Trypsin Inhibitors)—proteins found in wheat that had already been shown in animal studies to cause inflammation and accelerate fatty liver progression.
These proteins serve plants as a defense against pests and are largely resistant to breakdown in the human digestive tract. They can stimulate immune receptors in the gut—specifically TLR4 receptors—triggering an inflammatory immune response. Additionally, ATIs appear to shift the microbiome toward an inflammation-promoting environment (Source).
Inflammation, in turn, promotes insulin resistance, and insulin resistance favors liver diseases like MASLD. A vicious cycle emerges.
The study participants, all of whom had fatty liver disease, were asked to avoid gluten-containing grains for 6 weeks.
The results after this short period were remarkable: the gluten-free (= ATI-free) diet led to significant improvements in liver and metabolic parameters as well as in symptom reports from patients.
Not only did participants lose significant amounts of liver fat as measured by ultrasound, but they also showed a slight decrease in BMI and an improvement in the HOMA Index, a marker of insulin resistance severity. According to the researchers, these positive changes are likely due to the reduced activation of the immune system in the gut from avoiding ATIs—in other words, less inflammation.
If you struggle with insulin resistance or already have fatty liver disease, it might be worth considering eliminating or at least reducing grain intake. Unlike celiac disease, where even tiny amounts can trigger a reaction, the effect of ATIs is dose-dependent. This means even a reduction in ATI consumption can have a very beneficial effect!
By the way: The magnitude of improvement in the study was comparable to some other highly effective interventions, such as exercise programs or even medications!
