Artificial sweeteners can make you gain those extra kilos

A wide-ranging review has found that long term use of the sweeteners - including aspartame, sucralose and stevia - may have negative effects on our metabolism and appetite, as well as our gut bacteria.

After looking at two types of scientific research, the authors conclude that there is no solid evidence that sweeteners like aspartame and sucralose help people manage their weight.

Seven of these studies were randomized controlled trials, considered to be the gold standard in clinical research, which included 1003 people followed for 6 months on average.

And while the longitudinal studies point to an association, they aren't able to determine cause and effect.

But surely a diet pop is a wiser choice than regular pop? The group represents the low- and reduced-calorie food and beverage industry.

Such strategies should address not only dietary preferences, but also physical activity and medical considerations, Rankin added.

The results of the study showed that sweeteners may help with weight loss if they become a one-to-one replacement for sugary drinks or food. BMI is a measurement of body fat, based on height and weight.

NIH pediatric endocrinologist Dr. Kristina Rother, who wasn't involved in the study, said it is a strong piece of work that highlights the need for more and better-designed studies on low-calorie sweeteners. "Everyone is told don't eat sugar, period". But they did not find concrete proof of causation.

One school holds that the sweeteners might influence dieters' behavior in unhealthy ways.

Numerous clinical trials this study drew on didn't align closely with the way people consume such sweeteners in the real world - for instance, trials generally give subjects diet soda or sweetener capsules, while ignoring other sources, such as food.

There are a bunch of hypotheses for why artificial sweeteners may not promote weight loss or health. Some researchers also believe that sweeteners may interfere with the body's mechanisms for metabolizing sugar.

The study highlights the fact that more research needs to be conducted before "the long-term risks and benefits of these products are fully characterized".

"Obesity is a major public health challenge that contributes to type 2 diabetes and cardiovascular disease", Meghan B. Azad, PhD, from George & Fay Yee Center for Healthcare Innovation, University of Manitoba, Canada, and colleagues wrote.

Lauri Wright is an assistant professor of nutrition and dietetics with the University of North Florida.

"It's many factors together that make up a healthy diet and lifestyle".

USA consumption of artificial sweeteners has increased dramatically over the past 15 years. Artificial sweeteners were the product of the need to provide a sweet experience to the ones who were supposed to steer clear of natural sugar. In 1965, only three per cent of people were drinking diet soda. "I feel like they've been well-tested, and I don't worry about normal consumption".
