Artificial Sweeteners Linked Directly to Obesity

Brian Turner

Posted on April 09 2018

More than 66 percent of Americans are obese or overweight. Many use calorie-free artificial sweeteners to help them lose weight. Diet sodas, for example, have been around since the early 1960s, yet obesity rates have exploded since then. Several recent studies have shown a link between obesity and being overweight, and the use of non-nutritive sugar substitutes. But, these studies didn’t show that these products caused the problem. An Israeli study showed that artificial sweeteners increased insulin resistance and changed the composition of intestinal bacteria that promoted obesity. This study was the first to demonstrate that non-caloric artificial sweeteners are directly linked to obesity. (Nature, 514:181-186)
