Study Overview
Brief Summary
The goal of this pilot study is to identify the role of satiety on responses to alcohol drinking using human subject laboratory methods. Satiety will be manipulated over two sessions using a dietary supplement (fiber+green tea) or a calorically matched placebo. Responses to an acute alcohol challenge are measured.
Detailed Description
Participants will receive a beverage containing either a dietary supplement (10g Fibersol®-2 mixed with water and aspartame sweetener for taste + 725mg decaffeinated green tea extract capsule) or a calorically matched placebo supplement (Aspartame sweetener mixed with water + aspartame capsule) counterbalanced at two separate visits. Forty-five minutes after the dietary supplement, a priming drink (calculated to achieve 0.03g/dL Blood Alcohol Concentration; BAC) is administered. Response to alcohol is measured using standardized questionnaires and a cognitive task. Then over a 2-hour period, additional mini-drinks are administered. Responses to standardized questionnaires are collected after each drink.

Outcomes
Primary Outcomes
Change in Alcohol Specific Satiety Score
Time Frame: baseline to 60 minutes
The Alcohol-specific Satiety Questionnaire is a 16-item instrument designed to measure satiety to alcohol's effects. Ratings are made from Not at all; 0 to Extremely; 10, yielding total scores from 0 to 160 with higher values representing greater alcohol-specific satiety.
Secondary Outcomes
- Change in Positive Affect Based on Subjective Effects of Alcohol Scale Score(baseline to 60 minutes)
- Change in Subjective Stimulation (Biphasic Alcohol Effects Scale)(baseline to 60 minutes)
- Change in Alcohol Urge Questionnaire Score(baseline to 60 minutes)
- Change in Attention Bias to Alcohol Score(30 minutes after alcohol administration)
- Change in Alcohol Demand Score(baseline to 60 minutes)
