Filter by:To compare, in a randomized, single-blinded, cross-over study the satiety effect of a very low energy aerated beverage with normal energy aerated beverages in healthy subjects.
To our knowledge no study has assessed the effects of a meal on neural responses to food cues and compared this with a condition simulating natural inter-meal hunger levels. This is important, as the existing literature often compares the effect of fasting to satiation, which may not reflect typical appetite processes. Thus, the purpose of this research was to examine the effect of a satiating lunch compared to a normal pre-meal state on blood oxygen level dependent (BOLD) activity in the human brain, as measured using functional magnetic resonance imaging (fMRI).
A 4 week double blinded parallel design with an intervention condition and a control condition will be employed. After having completed screening procedure and a baseline test day, participants will be randomized to either intervention or control condition. In the following 4 weeks, the participants will have to consume the distributed food product daily before completing another test day.
The objectives of the research are to assess the effects of increased protein and fiber intake at breakfast on neural activation in brain regions associated with appetitive drive and reward-driven eating, measures of subjective appetite, and ingestive behavior in overweight adults. Additional outcomes of interest include the effects of the breakfast intervention on blood sugar and cholesterol profiles.
The purpose of this study is to investigate the effect of eating various levels of mycoprotein (Quorn) on feelings of appetite, energy intake and levels of gut hormones in overweight volunteers.
Background: - Popular weight loss plans often restrict carbohydrates or fat. Research shows that very-low-carbohydrate (ketogenic) diets lead to greater weight loss than low-fat diets. Researchers want to know if eating fewer carbohydrates changes the number of calories the body uses. They also want to know how a ketogenic diet affects hunger, hormones, and food preferences. Objectives: - To better understand how the body responds to different diets. Eligibility: - Men 18 to 50 years old who are healthy but overweight. Design: - Participants will have 3 screening visits: 1. Medical history, physical exam, blood test, and EKG. They will eat during the visit. 2. For the week before the visit, participants will wear physical activity monitors daily. They will record everything they eat and sample the special diet. At the visit, they will receive an EKG and heart rate test while biking for 30 minutes. 3. For the week before the visit, participants will wear the physical activity monitors. They will eat all their meals from the special diet that will be provided. At the visit, they will answer questions and bike for 60 minutes. - After screening, for 1 week, participants will visit the clinic daily to receive that day s food. They will not eat or drink anything else except water. - Then participants will stay at the clinic for 8 weeks. They cannot leave but can have visitors. Participants will wear physical activity monitors, bike daily, and follow different diets. Tests will be given daily, and may include weighing, X-rays, and blood and urine tests. They will spend several days in a monitored room to test oxygen and carbon dioxide.
The study is an epidemiological survey to find out the incidence of loss of appetite in Indian patients suffering from various health disorders. This survey will be conducted to obtain information on appetite from a total of 17500 subjects This study does not intend to study the effect of any drugs. The primary source of information will be the subjects themselves. The study will be conducted at 275 - 350 centres spread across India.This is a single visit study.The physician will conduct routine clinical, physical and general examination.
This study will determine which breakfast (egg breakfast or bagel breakfast) has the most beneficial effect on appetite.
This study will examine the independent and combined effects of energy density and eating rate on appetite and endocrine mediators of appetite. Increasing eating rate and energy intake are expected to additively increase energy intake.
The purpose of this study is to assess the effect of eating breakfast in combination with exercise on fat usage, appetite and brain performance later in the day.
