The Claim

Chronic use of low-calorie sweeteners in adults aged 60 and older is associated with a 0.80 kg/m² higher body mass index and a 2.6 cm larger waist circumference over a median follow-up of 10 years, after adjustment for diet quality, physical activity, smoking, and metabolic health.

In plain English

In adults aged 60 and older, long-term use of low-calorie sweeteners is linked to a 0.80 kg/m² increase in body mass index and a 2.6 cm increase in waist circumference over 10 years, even when accounting for diet, exercise, smoking, and metabolic health.

See the scientific wording

Chronic use of low-calorie sweeteners in adults aged 60 and older is associated with a 0.80 kg/m² higher body mass index and a 2.6 cm larger waist circumference over a median follow-up of 10 years, even after adjusting for diet quality, physical activity, smoking, and metabolic health, suggesting that these sweeteners may not support weight management in older populations.

Why this might work

When sweet tastes are detected but no calories follow, the brain reduces its reward response, causing the person to eat more food to feel satisfied. This extra eating, especially of calorie-dense foods, leads to fat building up around the organs in the abdomen.

  1. Study: Chronic Low-Calorie Sweetener Use and Risk of Abdominal Obesity among Older Adults: A Cohort Study

    This study found that older adults who regularly drank diet sodas or ate foods with artificial sweeteners tended to gain a little more weight and belly fat over 10 years than those who didn’t, even when they ate well and exercised. So, sweeteners might not help with weight loss after all.
