Abstract

The possible effects on body weight of chewing gum on a regular schedule have not been tested in a randomized controlled trial (RCT). We conducted an 8-week RCT in 201 overweight and obese adults to test the hypothesis that receiving printed material on good nutrition and chewing gum for a minimum of 90 min/day (n = 102) would lead to greater weight loss than receiving printed nutrition information only (n = 99). Changes in BMI, waist circumference, and blood pressure were secondary outcomes. Adherence to the gum-chewing protocol in the intervention group was >95%. In the intention-to-treat analysis, there were virtually no changes in weight or BMI in either group between baseline and the end of the intervention at 8 weeks. Waist circumference decreased significantly in the intervention group between baseline and 8 weeks (mean ± SD change = -1.4 ± 5.3 cm; P = 0.0128); however, there was no significant difference in change in waist circumference comparing the groups. Similarly, systolic and diastolic blood pressure decreased significantly in the intervention group between baseline and 8 weeks (-3.0 ± 9.9 mm Hg; P = 0.0032 and -3.2 ± 7.3 mm Hg; P = 0.0001, respectively); however, there were no significant differences in the changes in systolic or diastolic blood pressure between the groups. Analyses including completers only produced essentially the same results. We conclude that chewing gum on a regular schedule for 8 weeks did not facilitate weight loss in these overweight and obese adults.​

והמחקר הכי מטומטם לשנת 2011, הוא ...

אני חושב שהוא זוכה בתואר המחקר הכי מטומטם בעשור. ואולי גם במאה. ואולי גם במילניום. ואולי גם מאז המהפכה התעשייתית.

 

[אבי כהן]

מטומטם כן, אבל לטעמי פחות מההוא הקודם שהבאת (עם ה "לא נגעתי, אחי")

ההוא מחקר של פסיכולוגי ספורט אז ניחא. אבל מי כל כך טיפש כדי לעשות מחקר שכזה?
אולי הם יעשו מחקר המשך עם סוכריות ללא סוכר.
