Surprising Findings
High fructose intake (24% of calories) for 7 days did not reduce insulin sensitivity or increase insulin levels.
Many assume fructose directly causes insulin resistance, especially in high-risk groups like obese teens. This result challenges that assumption — at least in the short term.
Practical Takeaways
Reducing sugary drinks may still be wise, but the main goal should be managing total calorie intake rather than fearing fructose alone.

Eating a lot of fructose for just one week might pack more fat into your liver and make it harder for your body to respond to insulin, even if you're otherwise healthy.
If obese teens eat more fructose for a week — like swapping some carbs for sugary foods — but don’t eat more calories overall, it doesn’t seem to change how their body handles sugar or fat, at least in the short term.
If obese teens eat a lot of fructose — up to a quarter of their daily calories — for a week, it won’t mess with their insulin as long as they don’t eat more calories than usual.
If obese teens eat way more fructose for a week — but don’t eat more total calories — it doesn’t seem to change their blood sugar, insulin, or cholesterol levels.
Eating a lot of fructose — up to a quarter of your daily calories — for a week doesn’t mess with your blood sugar or insulin levels if you're a healthy, obese teen and you're not eating extra calories.
