Filter by:Comprising two experiments, the investigators assessed the metabolic, endocrine and appetite-related responses to acute (1-d, part 1) and daily mid-morning milk consumption (28-d, part 2) in adolescent males (15-18 y).
The purpose of this study is to investigate whether a combination of taste probes and food-related cues can induce dopamine release in striatal and extra-striatal brain regions in healthy subjects.
The purpose of this study is to examine the influence of a medicinal cannabinoid agonist versus placebo on behavioural and gut peptide responses to food images and food intake.
The aim of this study is to contribute to a better understanding of how dietary fibre in rye affects appetite and metabolic processes. We will evaluate how the intake of rye crisp breads affects appetite, insulin secretion and glucose levels in the blood in healthy humans. We will also investigate microstructural properties of the crisp breads with microscopy, as well as to characterize the food products with respect to the content of dietary fibre and certain bioactive compounds. The aim is also to try to elucidate how observed effects on appetite are related to changes in insulin and glucose levels, appetite related hormonal signals and microstructural properties to verify findings from previous studies.
Acute effects on appetite and metabolic function have been observed for whole-grain rye cereal products. The aim of this study is to evaluate if the appetite suppressing effect of a whole-grain rye breakfast cereal may be further enhanced by the addition of fermentable dietary fibre and plant protein. The aim is also to try to elucidate how observed effects on subjective appetite are mediated in terms of changes in hormonal signals, flow of nutrients in the blood and products from bacterial fermentation of dietary fibre, and to relate this to the different composition of the breakfasts.
This study compares the effects of isovolumetric (325 ml) preloads of chocolate milk supplemented with sodium alginates at incremental doses on inter-meal glucose levels, appetite scores and food intake in healthy adult men. The findings of this study will illustrate whether the addition of sodium alginate to chocolate milk will improve the glycemic properties of chocolate milk and will potentiate its satiating characteristics. This study will also elucidate whether sodium alginates, incorporated into chocolate milk, will influence glycemia, appetite sensations and food intake in a dose-dependent manner. It is hypothesized that there will be a synergy between milk and sodium alginate beyond either alone. When combined with milk components, sodium alginate is expected to improve glycemia and induce satiety more than does either milk alone or alginate alone.
The amount and kind of food which is ingested influences the regulation of meal size. Neural signals from the gastrointestinal tract travel via the vagus nerve to the brainstem and thalamus, which projects to the rest of the brain, in particular the hypothalamus, amygdala and primary sensory cortices. In neuroimaging studies in which the stomach was distended with a gastric balloon activation was observed in the right insula, left posterior amygdala, left posterior insula, left inferior frontal gyrus and anterior cingulate cortex. So far, no study has examined the effects of the ingestion or infusion of a food on the brain. In addition to neural signals, hormonal signals are important for meal termination. Hormones like insulin, ghrelin and cholecystokinin interact with gastric as well as sensory signals in the process of satiation, which ultimately leads to meal termination. The aim of this study is to investigate the interaction between food administration, hormone responses and brain responses. To this end an oral or intra-gastric load will be administered while measuring brain activity (functional magnetic resonance imaging) and hormone concentrations. Subjects will participate in one trainings session and in three functional magnetic resonance imaging (fMRI) sessions (35-min fMRI scan). A training session will take 40-minutes and consists of placing a naso-gastric tube and ingesting 500 ml of chocolate milk orally. The fMRI sessions will consist of three conditions: in condition one (A) 500ml of chocolate milk will be administrated orally. In condition two (B) and three (C) an intra-gastric load of 500 ml is administrated.
The purpose of this study is to determine the effect of different time of sleep restriction on control of food intake and metabolism of obese and normal subjects.
The aim of the ProSat study is to examine the effects of a probiotic capsule containing Lb. Casei on subjective appetite sensation, ad libitum energy intake, and appetite hormone response in a single meal test and to determine whether the acute effects persist after daily supplementation of the probiotic capsule.
Scientists have discovered a number of hormones that control our feelings of hunger and fullness. One particular hormone, called GLP-1, has been associated with feelings of hunger and fullness. The overall purpose of this study is to look more closely at how GLP-1 changes these feelings and to observe how these hormones affect the brain's function. To do this, volunteers will be asked to come to the clinic for a screening visit, and 2 study visits. This is an outpatient study with a screening visit which will last about an hour and the two subsequent study visits for about 3 hours each. During the study, patients will receive a drug that blocks the effect of a hormone made in the gut. We will take a series of blood samples to measure hormones and use functional magnetic resonance imaging (MRI) to take pictures of the brain. Understanding the action of these hormones in the brain may eventually lead to new ways to help people avoid obesity or lose weight.
