NCT ID: NCT04377282 Completed - Appetite Clinical Trials

The Effect of Buckwheat and Couscous on Satiety and Food Intake in Young Adults

Start date: March 2012
Phase: N/A
Study type: Interventional

A diet rich in whole grains has been linked to multiple beneficial health outcomes, including cardiovascular health, weight loss and a decreased risk of acquiring type 2 diabetes. However, grain products vary due to their botanical origin, composition, and post-harvest processing. While wheat is considered a dominant grain crop in Canada, the minor crops, including gluten-free buckwheat, become popular alternatives to wheat products such as couscous. Both buckwheat groats and couscous are traditionally consumed in the form of the porridge or side dish, however, their acute effects on satiety and food intake remain unknown. The objective of this study is to investigate the short-term effects of couscous and buckwheat on satiety and short-term food intake in young adult males.

NCT ID: NCT04212546 Completed - Body Weight Clinical Trials

Short and Long-Term Effects of Prebiotic, Probiotic and Synbiotic on Appetite and Dietary Intake

Start date: January 1, 2016
Phase: N/A
Study type: Interventional

Prebiotics and probiotics are thought to play a role in appetite control and body weight regulation; but little is known about this topic. This study was planned to examine the effects of inulin and Lactobacillus casei 431 on short and long term fasting, satiety, dietary intake, and serum hunger and satiety hormone levels. The study consisted of 2 phases. In the first phase, a double-blind, randomized, crossover study design was used, and it was performed with 16 healthy male participants aged 19-30 years. In this phase, the prebiotic (200mL milk+16g inulin), probiotic (200mL milk + Lactobacillus casei 431 [>106 cfu/mL]+16g maltodextrin), synbiotic (200mL milk+16g inulin + Lactobacillus casei 431 [>106 cfu/mL]) and control (200mL milk+16g maltodextrin) test drinks were consumed with a standard breakfast on four separate test days by one week intervals, and their effects on dietary intake, hunger, satiety and appetite were assessed. The second phase was performed with 21 healthy male participants aged 19-30 years, using a placebo-controlled double-blind, randomized study design. Participants consumed the control (200mL milk+16g maltodextrin) or synbiotic (200mL milk+16g inulin+ Lactobacillus casei [>106 cfu/mL]) test drinks for 21 days with their habitual diet. At the beginning and end of the intervention, blood samples were collected at 0., 30., 60. and 120. minutes following the test day protocol to analyse serum glucose, insulin, ghrelin, obestatin and PYY (peptide tyrosine tyrosine) levels. In addition, dietary intake, hunger, satiety and appetite of participants were compared.

NCT ID: NCT04151927 Completed - Clinical trials for Heart Rate Variability

Effects of Overnight Low Oxygen Exposure on Energy Balance

Start date: December 11, 2019
Phase: N/A
Study type: Interventional

This research study will evaluate changes in resting metabolic rate, appetite, and heart rate variability following overnight exposure (8 h/night) to normobaric hypoxia (NH) or normobaric normoxic (NN). In randomized order, participants will sleep one night in NH conditions (~15% oxygen; achieved with nitrogen dilution, equivalent to ~8500 feet elevation) and another night in NN (control) conditions (~20% oxygen; achieved with nitrogen dilution, equivalent to ~1000 feet elevation).

NCT ID: NCT04067466 Completed - Appetite Clinical Trials

Appetite Satisfaction and Short-term Satiety of Different Plant Compositions in the Adolescent Age Group

Start date: July 26, 2017
Phase: N/A
Study type: Interventional

This study evaluates the satiating effect of two types of food supplements made from various types of fibres in the subsequent intake of other foods, in satiety, and in the regulation of hormones

NCT ID: NCT03974165 Completed - Appetite Clinical Trials

Cereal-based Products Fortified With Legumes and Effects on Glycemic Control and Appetite Regulation

Start date: May 7, 2019
Phase: N/A
Study type: Interventional

Legumes are rich source of proteins and dietary fibers which are associated with satiety and amelioration of postprandial glycemic response. The purpose of the study is to examine the effects of cereal-based products fortified with legumes on appetite regulation and body weight management.

NCT ID: NCT03900130 Completed - Behavior Clinical Trials

The Omnibus Satiety Metric: Predicting Satiety in Humans Through Brain, Blood, and Subjective Data

OmniSaM
Start date: October 18, 2017
Phase: N/A
Study type: Interventional

Designing food and drink that maximizes satiety has long been an ambition of industry and public health. For obvious reasons, foods that fill faster and for longer are desirable to consumers for controlling their weight, and to public health programs that are designed to prevent obesity. Current methods for measuring satiety have weak predictive value, commonly fail to replicate, and are yet to be validated with respect to energy consumption in everyday life. The investigators propose to overcome this deficiency by developing the Omnibus Satiety Metric (OmniSaM). OmniSaM is proposed as a multi-modal metric that targets the full spectrum of processes underlying the satiety cascade, composing brain, blood, mind and behavior of consumers. As a proof-of-concept, subjects (normal BMI) will undergo a preload ad libitum paradigm, with a 2-parameter factorial design comparing milk based products differing in levels of caloric load and protein-to-carbohydrate ratio. The investigators will acquire 1. high-resolution neuroimaging data, whilst 2. simultaneously recording appetitive hormones, 3. blood metabolite composition, 4. subjective sensory indices of appetite and 4. behavioral metrics of consumption.

NCT ID: NCT03866720 Completed - Appetite Clinical Trials

Isolating & Exploiting the Mechanisms That Link Breakfast to Human Health - Acute

Start date: February 26, 2019
Phase: N/A
Study type: Interventional

Following the establishment of causal links between breakfast consumption, the individual components of energy balance, and health it is now important to examine and target the underlying biological mechanisms involved to maximise potential health benefits. To begin investigating the outlined mechanisms healthy, non-obese participants will be recruited to take part in phase I (acute crossover design) of a wider project.

NCT ID: NCT03701503 Completed - Obesity Clinical Trials

The Comparison of PYY, Ghrelin, GLP1, Glucose Level, Level of Satiety, and Ad Libitum Intake in Obese and Non-Obese Patients After Breakfast With Balanced Macronutrient Composition

Start date: October 2010
Phase: N/A
Study type: Interventional

Obesity can occur due to an imbalance of energy. This energy balance is greatly influenced by hunger and satiety. Obese person cannot resist hunger, while non obese can control hunger. Gut hormones, such as PYY and ghrelin, are associated with appetite and satiety control. This study's objective is to compare the effect of breakfast with balance composition on gut hormones, glucose and ad libitum intake four hours after breakfast between obese and non obese.. The research methodology was used a clinical trial with 18 obese women and 22 non obese women participants. Subjects were given a balance breakfast (protein 12,4%, carbohydrate 68,2%, fat 22,6%). Gut hormones (PYY, Ghrelin, GLP -1) level , Glucose level and satiety level were measured at 0, 15, 60, 120, and 180 minutes after breakfast. Ad libitum meal was given four hours after breakfast and measured after.

NCT ID: NCT03697486 Completed - Obesity Clinical Trials

The Effect of Breakfast With Different Macronutrient Composition on PYY, Ghrelin, GLP-1,Glucose Level, VAS for Hunger, VAS for Satiety and Ad Libitum Intake 4 Hours After Breakfast in Obese Women

Start date: October 2010
Phase: N/A
Study type: Interventional

Gut hormones, such as PYY and ghrelin, are associated with appetite control and obesity. Protein is thought to be the most satieting nutrient and could affect production of several gut hormones. This study's objective is to find the effect of breakfast with different protein composition on PYY, ghrelin, and ad libitum intake four hours after breakfast. The research methodology was used a clinical trial with 22 obese women participants. Subjects were given three types of breakfast: low protein consumption (12.4% protein), medium protein (23.5% protein), and high protein (40,6% protein). PYY and ghrelin level were measured at 0, 15, 60, 120, and 180 minutes after breakfast. Ad libitum meal was given four hours after breakfast and measured after.
