Soda ban at work shrinks waistlines? new study investigates
NCT ID NCT05972109
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a two-part approach to help employees lose belly fat and improve insulin sensitivity: a workplace ban on sugary drinks and a single counseling session. Over 600 full-time employees who drank at least three sugary beverages a week took part. Researchers measured changes in waist circumference and insulin sensitivity over 12 months.
