The Study
The Effectiveness of High Protein and Low Carbohydrate Diet on Reducing Pro-Inflamatory Activity in Rattus Norvegicus using PCOS Model
This study tested a special diet on a few rats that were made to act like they have PCOS. It found that the rats' inflammation markers went down, but that doesn't mean the same diet will work for people. It's like testing a new toy on a robot dog — it might work for the robot, but not for a real dog.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Scientists gave rats with PCOS-like symptoms either normal food or a low-carb, high-protein diet to see if it reduced inflammation markers.

Key takeaways
Summary
Based on the study abstract and findings.
- 1This was seen only in rats with a lab-induced condition; it’s unknown if this applies to humans with PCOS.
- 2Rats on the low-carb, high-protein diet had about 55 units lower AGEs and 55 ng/mL lower IL-6 than rats on normal food.

Consuming carbohydrates raises blood sugar, which can cause sugars to attach to proteins in cells, triggering widespread inflammation in the body.
In rats with a form of PCOS induced by testosterone and insulin resistance, a diet lower in carbohydrates and higher in protein for 20 days was linked to lower levels of two inflammatory markers, interleukin-6 and Advanced Glycation End Products, compared to a standard diet. It is not known whether this applies to humans with PCOS.
In rats with a condition mimicking PCOS and insulin resistance, a diet lower in carbohydrates and higher in protein for 20 days lowered levels of the inflammatory marker interleukin-6 compared to a standard diet.
In rats with a form of polycystic ovary syndrome induced by testosterone and insulin resistance, a diet lower in carbohydrates and higher in protein for 20 days lowered levels of Advanced Glycation End Products in the blood compared to a standard diet.
In rats with a laboratory-induced form of PCOS, the level of a specific inflammatory marker called IL-6 in the blood was not higher than in rats without PCOS, when both groups ate the same diet.
In rats with a lab-induced form of PCOS, blood levels of Advanced Glycation End Products (AGEs) were similar to those in healthy rats, indicating that the PCOS induction method did not increase AGEs under these conditions.
