The Effects of Beverages on Food Liking

Withdrawn before enrolling · Not applicable

Conditions studied: Obesity

In brief

The use of non-nutritive sweeteners (NNS) in replacement of nutritive sweeteners (NS) could be a potential weight loss strategy as it may reduce energy intake. One concern with the replacement of NS with NNS is the risk of caloric compensation after consumption of NNS. Most studies have examined the effect of NNS foods and beverages on energy intake in the short-term (one-day or less), with results suggesting lack of compensation in the very short-term (less than one day), and then compensation, or over compensation, when the NNS products are consumed on one day with measures of energy intake taken over 1 to 2 days (Anton et al., 2010; Lavin et al., 1997; Overduin et al., 2016; Appleton et al., 2007; Piernas et al., 2013). Given these mixed results, it is still not clear if NNS foods and beverages are a beneficial strategy for decreasing energy intake. However most studies have been in lab-based settings, in which participants are consuming provided food at specific times. No study has reported on the effect of NNS foods or beverages consumed over several days and energy intake on these days when participants are in free-living situations. Therefore, the purpose of this investigation is to evaluate how NNS beverage consumption affects energy intake in free-living situations over a span of three days. Through a 3x4 mixed design, participants will be randomized into one of three groups: NNS beverage, NS beverage, or carbonated water (control). Participants will be encouraged to go about their normal daily activities and not change any other aspect except for drink consumption. One baseline and three, 24-hour dietary recalls will be collected over the course of the study to analyze energy intake. The specific aim of this investigation is to determine if caloric compensation occurs during 3-day exposure to NNS beverages.

Who can join

Age: 18 and older, up to 35. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• The eligible age range of participants will be 18-35 years. The age range for eligible participants was set because research has shown taste sensitivity declines after the age of 60. In 2001, Mojet and colleagues used sucrose and aspartame to test taste threshold sensitivity in young adults age 19-33 years and elderly adults age 60-75 years. Results showed a decrease in threshold and taste in the elderly adults (Mojet, et al., 2001). Sensitivity to the five basic tastes, sweet, salty, sour, bitter, and umami, begins to decline after the age of 60 ("Aging changes in the senses," n.d.).
• Individuals with overweight or class I obesity - Body mass index (BMI) range 25-34.9 kg/m2
• Does not participate in more than 100 minutes of structured, moderate- to high-intensity physical activity weekly
• Consumes > 36oz of NS beverages daily as assessed by the Beverage Questionnaire (BEVQ)-15 (Hedrick, et al., 2012) - NS beverages include: 100% fruit juice, sweetened juice beverages, energy and sports drinks, sweetened tea or coffee, and soft drinks.
• Willing to substitute NS beverages for NNS beverages or carbonated water for a three-day period
• Able to complete all study days consecutively, with all study days following usual schedules and activities (i.e. not traveling)
• Report a favorable preference for the beverages involved in the study, with participants rating each beverage item ≥3 on a 5-point Likert scale during the phone screen
• Reports a usual wake up time of 10:00a.m or earlier on Mondays through Fridays.
• Reports no known allergic reaction to metal

You may not qualify if…

• Report of current dieting or dieting within the past month
• Report of known reactions to sugar or NNS
