Weight Loss

Yaconz yacon syrup is one of the best dietary sources of fructooligosaccharides (FOS), a type of fructan. Fructans are a category of soluble dietary fibre. Because a large part of yacon syrup isn’t digested, it has only a third of the caloric value of sugar. For this reason, it can be used as a low-calorie alternative to sugar.

A 2009 study in Clinical Nutrition took a look at how daily consumption of syrup made from yacon root affected weight loss and blood sugar, and according to researchers,

“Daily intake of yacon syrup produced
a significant decrease in body weight, waist
circumference and body mass index.”

They also found that when the bacteria digest the fructans, they produce short-chain fatty acids (SCFA) that have powerful anti-obesity effects.

There is also some evidence that fructans can lower the hunger hormone ghrelin, helping reduce appetite.
