La description
Inclusion Criteria:
- Individuals aged 18 to 60 years.
- Any sex, gender, or orientation.
- Self-reported good health.
- No medication use.
- No allergies or food sensitivities to any of the foods used in the study.
- No anticipated change in physical activity during the study period.
- Willingness to complete all planned study activities, including the screening visit and four test visits.
- At screening, participants must rate the selected high-palatability foods between 60 and 90 on a 100-unit visual analog scale, where 100 = extremely palatable.
- At screening, participants must rate the selected low-palatability foods between 10 and 40 on a 100-unit visual analog scale.
Exclusion Criteria:
- Younger than 18 years or older than 60 years.
- Current medication use.
- Allergies or food sensitivities to any study foods.
- Not meeting the required palatability rating ranges during screening.
- Anticipated change in physical activity during the study period.
- Not self-reporting good health.
- Unwillingness or inability to complete the planned study activities.

Expérimental: Palatable Ultra-Processed Food
Participants will consume a palatable ultra-processed test meal during one study visit.
The meal will be used to assess appetite sensations, palatability ratings, and gastrointestinal transit time.
|
Participants will consume a palatable ultra-processed test meal during one study visit.
The meal will consist of commonly available ultra-processed food items and will be used to assess appetite sensations, meal palatability, and gastrointestinal transit time.
|
|
Expérimental: Unpalatable Ultra-Processed Food
Participants will consume an unpalatable ultra-processed test meal during one study visit.
Palatability will be reduced by adding bitter melon powder.
The meal will be used to assess appetite sensations, palatability ratings, and gastrointestinal transit time.
|
Participants will consume an unpalatable ultra-processed test meal during one study visit.
Palatability will be reduced by adding organic bitter melon powder to the ultra-processed meal.
The meal will be used to assess appetite sensations, meal palatability, and gastrointestinal transit time.

|
Expérimental: Palatable Non-Ultra-Processed Food
Participants will consume a palatable non-ultra-processed test meal during one study visit.
The meal will be used to assess appetite sensations, palatability ratings, and gastrointestinal transit time.
|
Participants will consume a palatable non-ultra-processed test meal during one study visit.
The meal will consist of commonly available non-ultra-processed food items and will be used to assess appetite sensations, meal palatability, and gastrointestinal transit time.

Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Orocecal Transit Time
Délai: During each test visit, up to 4.5 hours after meal consumption
|
Orocecal transit time will be assessed using hydrogen analysis of end-alveolar breath samples collected after consumption of each test meal.
Each test meal will contain lactulose as a marker of gastrointestinal transit time.
|
During each test visit, up to 4.5 hours after meal consumption
|
|
Appetite Sensations
Délai: During each test visit, up to 4.5 hours after meal consumption
|
Appetite sensations, including hunger, fullness, desire to eat, prospective food consumption, and thirst, will be assessed using 100-mm visual analog scales during each test visit after consumption of the assigned test meal every 30 minutes.
Each visual analog scale ranges from 0 to 100 mm, with higher scores indicating a greater intensity of the rated sensation.
Higher scores are not inherently better or worse outcomes, but reflect greater hunger, fullness, desire to eat, prospective food consumption, or thirst, depending on the item.
|
During each test visit, up to 4.5 hours after meal consumption
|
|
Meal Palatability Ratings
Délai: During each test visit, up to 4.5 hours after meal consumption
|
Meal palatability will be assessed using a 100-mm general labeled magnitude scale during each study visit.
The scale ranges from 0 to 100 mm, with 0 mm anchored by "most disliked sensation imaginable," 50 mm anchored by "neutral," and 100 mm anchored by "most liked sensation imaginable."
Higher scores indicate greater liking of the test meal and therefore a more favorable palatability rating.
|
During each test visit, up to 4.5 hours after meal consumption
