What 23,000 Adults Had to Say About Low-Calorie Sweeteners and Weight Loss
Research on regular users of low-calorie sweeteners has found they have better diets than
nonusers. If that isn’t incentive to use them, I don’t know what is! Of
course, adding a low-calorie sweetener to your coffee isn’t all it
takes to become healthy and thin, but studies show it can be part of a
healthy lifestyle for many people and helps them reach their goals. And
that’s exactly what the latest study by researchers Adam Drewnowski and Colin Rehm at the University of Washington found.
Since other research has reported an association between low-calorie sweeteners and obesity by simply looking at who was using them and their weight classification, Drewnowski and Rehm wanted to answer the question, “What came first, the weight gain or the use of low-calorie sweeteners?”
In their study, they went back 10 years to see peoples’ weight histories and their intent, or motivation, to lose weight during that time. What they found is the use of low-calorie sweeteners was common among people who were experiencing weight fluctuations and who were trying to return to a lower weight. In fact, nearly one-third of adults trying to lose or maintain weight used low-calorie sweetened products.
As anyone who has lost weight knows, it is easy to regain. When that starts to happen, there is a tendency to resume the weight loss strategies that helped in the past, like using low-calorie sweeteners. Even people experiencing weight gain for the first time and those with the early warning signs of diabetes may decide to use low-calorie sweeteners as a first step to reduce their caloric intake or added sugars in their diet. In both these examples, the low-calorie sweetener was selected after the problem of weight gain or prediabetes was identified, not the other way around.

Asking the Right Questions
Here’s how the study was done.
Information
was collected from more than 22,000 adults about their use of
low-calorie sweeteners in the past 24 hours, their intent to lose or
maintain weight over the past 12 months and their 10-year weight
history. Height and weight records were used to classify the
participants as normal weight, overweight or obese during the period
under investigation and a questionnaire was completed to determine if
they had been diagnosed with diabetes.
Drawing the Right Conclusions
What the researchers found was the use of low-calorie sweeteners was associated with self-reported intention
to lose weight during the previous 12 months, indicating it was a
strategy being selected to help with weight loss. They also found
those who reported they were trying to lose or maintain weight
during the past 12 months were much more likely to use low-calorie
sweeteners, and this was true for participants at any weight, not just
those who were overweight or obese. This finding provides the strongest
evidence yet that low-calorie sweeteners do not cause weight gain, but
are chosen to help prevent it.
They also found those who reported they were trying to lose or maintain weight during the past 12 months were much more likely to use low-calorie sweeteners.
A
final conclusion drawn from this research, based on the analysis of the
10-year weight change data, is that obese individuals may have switched
to diet beverages made with low-calorie sweeteners after they
gained weight. This supports the possibility that use of low-calorie
sweeteners may be a useful “marker” to identify people have experienced
weight gain and are trying to reduce it.
What Does This Mean For You?
We
now have better evidence than ever that low-calorie sweeteners are
deliberately chosen by individuals as a weight management strategy and
do not contribute to weight gain. Using low-calorie sweeteners in place
of sugar is a simple step anyone can take to help reduce their caloric
intake as part of a healthy lifestyle.
