Brief summary
This single-center, single-blind, non-randomized crossover exploratory study evaluated the short-term effects of NatureU Burn on postprandial satiety in healthy adults. NatureU Burn is an oral dietary supplement containing Irvingia gabonensis seed extract and high-molecular-weight inulin. Fourteen healthy adults were enrolled, and 12 participants completed the study and were included in the effectiveness analysis. Each participant completed two test sessions separated by at least 48 hours: a reference food session with 75 g medical anhydrous glucose in 250 mL warm purified water and a test food session with one capsule of NatureU Burn plus 75 g glucose in 250 mL warm purified water. Satiety-related questionnaire scores were assessed at fasting baseline and at 30, 60, 90, 120, 180, and 240 minutes after the first bite in each session. The study assessed fullness, hunger, desire for food, and prospective food consumption, and monitored adverse reactions.
Detailed description
This exploratory clinical study was conducted to assess whether NatureU Burn, when consumed with a glucose reference food, was associated with changes in satiety-related subjective indicators compared with glucose alone. Eligible healthy adults completed screening, signed informed consent, and underwent two independent test sessions. For 2 days before each test, participants were instructed to maintain regular routines and a normal diet. On the day before testing, participants ate dinner between 18:00 and 20:00, avoided high-fiber and high-sugar foods, and fasted after 20:00. On the test morning, participants avoided strenuous exercise, sat quietly for 10 minutes before testing, and completed a fasting satiety scale before taking the assigned food. Participants consumed the assigned food and water within 5 to 10 minutes, and completed the satiety scale at 30, 60, 90, 120, 180, and 240 minutes after the first bite. The four evaluated satiety indicators were fullness, hunger, desire for food, and prospective food consumption. Food-affected changes were calculated relative to fasting baseline and compared between the NatureU Burn plus glucose session and the glucose reference session. Safety monitoring included adverse reactions throughout the testing process.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Food-Affected Fullness Score After NatureU Burn Plus Glucose Compared With Glucose Alone | Fasting baseline before food intake and 30, 60, 90, 120, 180, and 240 minutes after the first bite in each test session. | Fullness was assessed using the satiety scale. Food-affected fullness was calculated as the change from fasting baseline at each postprandial time point and compared between the NatureU Burn plus glucose test session and the glucose reference session. Fullness was assessed using the fullness item of the 100-point Satiety Rating Scale. The scale ranges from 0 to 100, with higher scores indicating greater fullness and a better satiety outcome. Food-affected fullness was calculated as the change from fasting baseline at each postprandial time point and compared between the NatureU Burn plus glucose test session and the glucose reference session. A larger positive change from baseline indicates a greater increase in fullness |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Food-Affected Hunger Score After NatureU Burn Plus Glucose Compared With Glucose Alone | Fasting baseline before food intake and 30, 60, 90, 120, 180, and 240 minutes after the first bite in each test session | Hunger was assessed using the satiety scale. Food-affected hunger was calculated as the change from fasting baseline at each postprandial time point and compared between the NatureU Burn plus glucose test session and the glucose reference session.Hunger was assessed using the hunger item of the 100-point Satiety Rating Scale. The scale ranges from 0 to 100, with higher scores indicating greater hunger and a worse satiety outcome. Food-affected hunger was calculated as the change from fasting baseline at each postprandial time point and compared between the NatureU Burn plus glucose test session and the glucose reference session. A larger negative change from baseline indicates a greater reduction in hunger. |
| Food-Affected Desire for Food Score After NatureU Burn Plus Glucose Compared With Glucose Alone | Fasting baseline before food intake and 30, 60, 90, 120, 180, and 240 minutes after the first bite in each test session | Desire for food was assessed using the satiety scale. Food-affected desire for food was calculated as the change from fasting baseline at each postprandial time point and compared between the NatureU Burn plus glucose test session and the glucose reference session.Desire for food was assessed using the desire-for-food item of the 100-point Satiety Rating Scale. The scale ranges from 0 to 100, with higher scores indicating greater desire for food and a worse satiety outcome. Food-affected desire for food was calculated as the change from fasting baseline at each postprandial time point and compared between the NatureU Burn plus glucose test session and the glucose reference session. A larger negative change from baseline indicates a greater reduction in desire for food |
| Food-Affected Prospective Food Consumption Score After NatureU Burn Plus Glucose Compared With Glucose Alone | Fasting baseline before food intake and 30, 60, 90, 120, 180, and 240 minutes after the first bite in each test session | Prospective food consumption was assessed using the satiety scale. Food-affected prospective food consumption was calculated as the change from fasting baseline at each postprandial time point and compared between the NatureU Burn plus glucose test session and the glucose reference session. |
