NCT02134938

Brief Summary

The purpose of this study is to assess whether low caloric, low energy density, konjac food products are effective in appetite regulation when administered as caloric replacements. It is hypothesized that replacement of typical, balanced, vegetarian meals with konjac food products will have comparable satiety scores, decreased postprandial glucose response, and will not significantly affect subsequent food intake.

Outcome Measures

Primary Outcomes (1)

  • Subjective Satiety

    Subjects will record their subjective satiety ratings using a 100 mm visual analogue scale and these ratings will be combined into a total subjective appetite score using the formula (Q1+Q2+(100-Q3)+Q4)/4.

    12 hours for each of the 3 study visits.

Secondary Outcomes (6)

  • Ambulatory Blood Pressure

    Measured at the beginning of each of the 3 study visits and every 30 minutes thereafter until 10:00pm the same day.

  • Height and Weight

    Taken once at the beginning of each of the 3 clinical visits.

  • Blood Samples

    One sample taken immediately prior to (0min) eating each meal (Breakfast, Lunch, Snack and Dinner) and at 30, 60, 90 and 120 min after eating the Breakfast and Lunch meals for each of the 3 study visits (total of 12 blood samples per study visit).

  • Palatability Scores

    Measured immediately after eating and finishing (<15min after the first bite) each meal (Breakfast, Lunch, Snack and Dinner) for each of the 3 study visits.

  • Food Craving Rating

    Rated immediately prior (0min) to eating each meal (Breakfast, Lunch, Snack and Dinner) for each of the 3 study visits.

  • +1 more secondary outcomes
