The Study
1912-LB: Effect of a Four-Week Low-AGE Diet on Liver Insulin Sensitivity, Visceral Adiposity, and Inflammation in Young Adults with Prediabetes—A Randomized Controlled Trial
This study gave two groups of young people different diets for four weeks and saw what happened to their bodies. It shows that one diet seemed to help their blood sugar and fat levels get better, but it doesn't prove the diet will stop them from getting diabetes later.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
This study tested if eating food cooked at low temperatures (less grilled, fried, or processed) helps young people with prediabetes feel better and lower their risk of diabetes.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — these changes are meaningful because they target early signs of diabetes (liver resistance and belly fat) without needing to lose weight or eat fewer calories.
- 2After 4 weeks, people on the low-AGE diet had 15% better liver insulin sensitivity, 8–10% less belly fat, 15–20% less inflammation, and less AGEs in their skin — but their pancreas didn't make more insulin.

When you cook food at high heat—like grilling or frying—it creates harmful compounds called AGEs, which can trigger your body’s inflammation system, making you more prone to chronic swelling and related health issues.
Young adults with prediabetes who follow a low-dAGE diet for four weeks, limiting intake to 16 mg per day or less, show a 15.2% increase in liver insulin sensitivity and a 12.7% decrease in liver insulin resistance.
In young adults with prediabetes, eating a diet low in advanced glycation end products for four weeks leads to an 8–10% reduction in visceral fat, even when total calorie intake remains unchanged.
Young adults with prediabetes who follow a low-dAGE diet for four weeks experience a 15–20% reduction in serum C-reactive protein levels, regardless of changes in body weight or fat mass.
In young adults with prediabetes, a four-week low-dAGE diet does not change pancreatic beta-cell function, as measured by the disposition index, even if insulin sensitivity improves.
Cooking carbohydrate- and protein-rich foods at high temperatures produces compounds called advanced glycation end products that trigger systemic inflammation.
