A Study of NatureU Burn on Satiety in Healthy Adults

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.

Slowly Digestible Carbohydrates for GLP-1 Secretion

The goal of this clinical trail is to learn if the hormone, glucagon-like peptide-1 (GLP-1), is stimulated by slowly digestible carbohydrates (SDCs) in healthy adults. In the current study, researchers will observe the amount of SDC that results in clinically meaningful levels of GLP-1, shown by an increase in feelings of fullness and a decrease in hunger, and how long an elevated level of GLP-1 lasts after starch consumption. Researchers aim to address two questions: What amount of SDC maximizes GLP-1-mediated satiety, and does the impact to satiety continue in a second meal? The overall goal is to maximize ileal-digesting SDC's potential use as a food-based agent for weight loss. Researchers will compare 20, 40, and 60 g of raw corn starch compared to a maltodextrin control on total plasma GLP-1 concentrations, insulin, and blood glucose at baseline and 15, 30, 60, 90, 120, and 180 minutes post-consumption of SDC. Researchers will also measure satiety at baseline, 60, 120, 180 minutes and after a second meal. There will be a total of 4 study visits with a least a 7-day break between visits. At each study visit, participants will: * Consume a randomized test beverage (SDC or maltodextrin) * Receive a blood draw at 7 timepoints over 3 hrs * Take a satiety questionnaire 5 times over 3 hrs * Consume a standardized lunch 3 hrs after the test beverage consumption

The Effects of Four Instant Maize Porridges on Satiety Measures

This study is designed to test the hypothesis that whole-grain forms of maize meal enhance and prolong satiety post-meal consumption.

A Comparison of Satiety Effects Two Commercially Available Snack Bars

The researchers are investigating the satiety effects of two commercially available snack bars. Qualified participants are age 18-65 with a body mass index of 18.5 to 29.9 kilograms of body weight per meter squared in height who are in good metabolic health. Participants will engage in two study visits conducted at the Indiana University--Bloomington Innovation Center. Study visits are separated by a 1-14 day washout period. Prior to each study visit, participants are asked to engage in normal activity and to refrain from strenuous exercise. Furthermore, subjects are asked to consume a typical diet the day prior to the study visit with one caveat; they are to consume standard frozen dinners (evening meal) of their choosing between 7-8 PM and to remain fasted afterward except for water and non-caloric beverages until the study visit the following day. The amount of food provided for the evening meal is estimated using a standard calorie calculator based on the Mifflin-St. Jeor equation and an estimate of their activity level. Subjects are instructed to consume only as much of the provided food as needed to become comfortably full as they would ordinarily. Subjects record their diet for the day. Upon arrival at the Innovation Center between 8-8:40 AM, compliance with the prior day protocol is verified through interview, and the diet record is reviewed. Participants consume 300 kcal of snack bars and complete visual analogue scales to assess hunger, fullness, desire to eat, and satisfaction at fasting and at 30 minute intervals from the fasting measurement for 2 hours. Immediately after consuming the snack bars, subjects complete a sensory evaluation of the snack bars. Fifteen to thirty minutes after completion of the final visual analogue scale, subjects will be presented with an individual buffet which they consume ad libitum until comfortably full. A second study visit that mirrors the first but with different bars is conducted after the washout period (1-14 days).

A Clinical Trial to Determine the Safety and Efficacy of an Origin Satiety Complex on Self-reported Hunger and Satiety in Healthy Adults

The goal of this clinical trial is to the safety and efficacy of the investigational product (IP), Origin Satiety Complex, on hunger and satiety in healthy adults. The main question it aims to answer is what is the difference in the net incremental area under the curve (niAUC) for self-reported postprandial hunger and satiety (T = 0 - T = 10.5 h), as assessed by satiety and hunger items of the Eating Behavior Visual Analog Scales (VAS), between the IP and placebo.

Effects of Fresh Mango Pulp Consumption on Satiety and Cardiometabolic Health

The objective of the study is to determine the effects of fresh mango pulp consumption on satiety and metabolic parameters in overweight/obese adults.

Effects of Fresh Watermelon Consumption on Satiety and Cardiometabolic Health

The goal of the proposed study is to determine the effects of fresh watermelon fruit consumption on satiety, metabolic parameters and weight management.

Effects of Watermelon Consumption on Satiety and Digestive Health

The objective of the proposed research is to determine the effects of watermelon (fruit and rind blenderized) on satiety, metabolic markers, bowel habits, microbiome and weight management in children and adults

Effects of Snack Types on Acute Glucose and Insulin Response

The purpose of the present study was to determine the effects of different type of snack consumption on postprandial satiety, glucose, insulin, antioxidant capacity and anxiety in healthy subjects.

Effects of Mixed Nut Consumption on Satiety and Weight Management

The first goal of the proposed study is to determine acute and long-term effects of mixed nuts (almonds, hazelnuts, pecans, pistachios, walnuts, and peanuts) on metabolic parameters and weight management. While numerous studies have shown the beneficial effects of nuts on promoting negative energy balance and weight loss, mechanistic studies exploring how the inclusion of nuts in the diet promotes a negative energy balance and weight loss have not been conducted. The second goal is to determine the mechanisms by which mixed nut consumption regulates of food intake and body weight.

Effects of Protein Supplementation on Brain Function

Protein-rich foods may improve brain insulin-sensitivity, which is important for cognitive and metabolic health, and may also translate into an improved food intake regulation. It is therefore pertinent to delineate the effects of plant-derived proteins, which are a more sustainable alternative to animal-derived proteins, on brain insulin-sensitivity and related functional benefits. The hypothesis is that daily plant-derived or animal-derived protein supplementation improves brain vascular function and insulin-sensitivity, thereby improving cognitive performance and appetite control in overweight or obese older men and women. The primary objective is to investigate in overweight or obese older adults the effect of daily protein supplementation for two weeks with either a plant-derived protein or an animal-derived protein on vascular function and insulin-sensitivity in the brain, while changes in cognitive performance and appetite-related brain reward activity will also be evaluated (secondary study objectives). Cerebral blood flow responses before (brain vascular function) and after the administration of intranasal insulin spray (brain insulin-sensitivity) will be quantified by the gold standard magnetic resonance imaging (MRI)-perfusion method Arterial Spin Labeling (ASL).
