Effects of Dietary Fructose Restriction on Liver Fat, De Novo Lipogenesis, and Insulin Kinetics in Children With Obesity.

Randomized Controlled Trial
Human
2017 Sep

The study replaced sugar with starch in the diets of kids who usually ate a lot of sugar, and after 9 days their liver fat dropped—even though they didn’t lose weight. This supports the idea that cutting back on fructose quickly improves liver fat.

Isocaloric Fructose Restriction Reduces Serum d-Lactate Concentration in Children With Obesity and Metabolic Syndrome.

Randomized Controlled Trial
