47 Clinical Trials for Various Conditions
This study is a randomized crossover trail examining the effect of breakfast consumption or omission on afternoon resistance training performance. Resistance-trained adults will complete a resistance training workout comprised of barbell back squat, barbell bench press, and barbell conventional deadlift following either consuming breakfast and lunch, or the same amount of food consumed solely at lunch. For each testing session the participants will be provided with all food to consume prior to arriving at the laboratory. Major performance outcomes will be total repetition volume completed for each exercise (i.e. bench press, squat, and deadlift) and the entire workout (each individual trial), along with barbell kinematics for each exercise.
This study is a 24-week crossover design study in adolescents enrolled in the 6-8th grade within the Center School District in the Kansas City, MO. This school will begin their 'Breakfast in the Classroom' program during the fall 2018 school year. Baseline data will be collected to include anthropometric measures, participant characteristics, and past eating habits. For the first 8 weeks, the students will be provided with breakfast meals containing the USDA nutrition requirements. These meals are typically higher in carbohydrates and lower in protein. For the second 8 weeks, the students will be provided with higher-protein breakfast meals. These meals also contain the USDA nutrition requirements but include high-quality protein-rich foods. For the remaining 8 weeks, the students will be provided both types of meals and will be permitted to choose which they prefer to consume each day. At the end of each 8-week period, eating habits, appetite, mood, cognitive performance, and anthropometrics will be completed along with measurements of breakfast waste.
This study will test whether whether the implementation of and Egg-cellent 'Breakfast in the Classroom' improves school breakfast participation and breakfast consumption in middle school adolescents; whether the implementation of 'Breakfast in the Classroom' improves appetite control, mood, cognitive performance, and unhealthy snacking behavior in middle school adolescents when compared to a traditional school breakfast program.
Adolescent obesity, negatively affecting the lives of over 18 million (34%) US adolescents, continues to be a major public health concern due to the increased risk of developing chronic diseases, including type 2 diabetes. Thus, there is a great need to develop effective, dietary strategies that target health outcomes, including weight management and glycemic control in young people. One particular strategy that is gaining scientific support includes the daily consumption of a protein-rich breakfast. This study will identify the potential role of protein at breakfast as a key component of a healthy diet for improvements in appetite control, satiety, and weight management to reverse the obesity epidemic and prevent and/or delay serious health complications in young people.
75 overweight, habitual 'breakfast-skipping' adolescents will complete the following long-term, randomized controlled trial. Participants will be randomly assigned to the following breakfast treatments: 350 kcal high protein breakfasts containing 30 g protein (primarily from lean beef), 35 g carbohydrates, and 10 g fat; 350 kcal normal protein breakfasts containing 10 g protein, 55 g carbohydrates, and 10 g fat; or will continue to skip breakfast. The following outcomes will be assessed during baseline and 4-month (post-intervention): body weight \& body composition; waist circumference; daily food intake; 24-h free-living glycemic control; and pre and post-prandial satiety. In addition, body weight and free-living breakfast intake (quantity, quality, and type) will also be assessed at 2-month follow-up
The purpose of this study is to examine the effects of breakfast skipping (SKIP) vs. the consumption of a high protein solid (HP-S) breakfast vs. the consumption of a high protein beverage (HP-B) breakfast on daily appetite control, food cravings, food intake, and sleep quality in young adults.
The goal of this study is to assess the effects of consumption of a lean pork-containing, high-protein breakfast versus a refined carbohydrate-rich breakfast on satiety and cardiometabolic parameters in overweight or obese adults with pre-diabetes.
The experiments in this study will assess if while following a reduced energy diet, eating a breakfast with higher protein quality will enhance weight loss compared to another breakfast with lower protein quality, but matched for energy density and macronutrient composition.
This is an experiment that will compare the effect of recommending breakfast consumption, or breakfast skipping, on body weight. Our objective is to determine if breakfast consumption recommendations can produce weight loss, and if that weight loss is dependent on typical breakfast eating habits.
The purpose of this study is to assess whether the daily addition of a protein-rich breakfast leads to beneficial changes in appetite control, food intake regulation,and cognitive function in overweight \& obese 'breakfast skipping' young women.
The purpose of this clinical trial is to investigate appetite responses to 2 cereal products in healthy adults.
This experiment will test the effects of healthy breakfast and morning exercise on children's focus and classroom behavior. Food and exercise each influence child focus, but little is known about their effects on classroom behavior and less about their combined effects. For one week (Monday-Friday), 10 children will be randomly assigned to receive healthy breakfast and morning exercise, 10 assigned to only healthy breakfast, 10 to only exercise, and 10 to neither. After exercise and breakfast, study staff will assess how focused children are during class-time, ask them to complete puzzle-like tasks, and wear a helmet that measures brain blood flow
The investigators will conduct an acceptability, feasibility, preliminary effectiveness trial of a 4-month, online, very low-carbohydrate breakfast-focused program in 120 adults with type 2 diabetes. The investigators will measure acceptability and feasibility, plus critical efficacy outcomes, such as changes in HbA1c, anti-hyperglycemic medications, glycemic variability, body weight, blood pressure, and lipids.
Purpose: To test how the presence of characters on breakfast cereals affects parents' perceptions and purchase intentions for their children. Participants: \~1,000 parents of children ages 2-12 Procedures: After completing a screener and reviewing a consent form, participants will complete two unrelated experimental studies. Participants will then move on to this study, where they will be randomized into conditions and view three breakfast cereal box images, with or without characters. They will then be asked a series of questions about their children and their perceptions about the breakfast cereals
Executive control processes involve initiate, coordinate, synchronize, and regulate elemental cognitive functions for the conduct of goal-directed behavior. The proposed research investigates whether exposure to a web-based training protocol designed to enhance executive control processes will improve cognitive performance in cognitively healthy older adults.
Exercising in the fasted state results in greater fat oxidation during exercise and results in decreased caloric intake in the meals after exercise. However, the studies that examine fasted vs. fed exercise utilize a carbohydrate-based breakfast, which can increase blood glucose and insulin concentrations, which is considered a negative consequence. A protein breakfast, which can increase satiety and rest of day energy intake could also increase resting energy expenditure as well as fat oxidation during exercise. However, comparisons between fasting exercise and pre-exercise breakfast macronutrient intake (i.e., carbohydrate vs. protein) have not been made. Therefore the purpose of this study is to investigate if eating breakfast and the composition of this breakfast before exercise has an effect on the food eaten throughout the rest of the day.
This study is being done to determine typical breakfast consumption habits in various populations of exercisers. Participants will be asked a series of questions pertaining to their participation in regular exercise, their current breakfast consumption, food preferences, meal timing, and general knowledge of sports nutrition and pre-exercise breakfast consumption.
One in every three children ages 2-19 years is overweight or obese. Although multifactorial in nature, obesity is primarily attributed to a mismatch between energy intake and energy expenditure (EE). Daily EE (DEE) can be partitioned between resting metabolic rate (RMR), EE associated with physical activity, and the thermic effect of food (TEF). RMR corresponds to the energy needed to sustain the body functions at rest and is also related to body composition (i.e., ratio of skeletal muscle mass to fat mass). Skeletal muscle mass is a large contributor to RMR; the more skeletal muscle mass, the higher the RMR (i.e., more energy expended at rest). In addition, muscle plays a central role in whole body protein metabolism and disrupted muscle metabolism is associated with the development of many common chronic diseases associated with obesity such as type 2 diabetes and cardiovascular disease. Although the contribution of disrupted muscle metabolism to chronic disease is well-established in older adults, the potential impact in children is unknown. The overall objective for this primary project application is to determine the role of breakfast protein consumption in improving energy metabolism, energy balance and skeletal muscle health in obese, school-aged children.
Assess the impact of 100% grape juice with a meal on postprandial glycemic response and subsequent appetite, food intake and cognitive function.
This study will determine the short-term postprandial effects of protein source at breakfast on energy metabolism, markers of metabolic health, appetite, and food intake and young and older men.
The purpose of this research is to determine if body composition influence the effect of breakfast composition on postprandial (post-meal) hunger, metabolic and energy expenditure response in normal weight, overweight, and obese young women.
The purpose of this study is to see what effect skipping breakfast versus consuming breakfast has on cognitive performance and the hormones responsible for glucose homeostasis in lean and obese adolescent males. The subjects will be tested on their ability to maintain attention when given several tasks called continuous temporal expectancy tasks (CTET) and electrophysiological signals using electroencephalogram (EEG) will be monitored. These two study groups will be randomized to one of two orders: (A,B) or (B,A) where A = breakfast intervention and B = no breakfast. There will be a washout period of 7 days in between study visits.
Purpose: To evaluate the effects of replacing breakfast with a high protein, high fat, high fiber meal replacement in overweight individuals, on body composition. Participants: Healthy, overweight and obese individuals (ages 18-45 yrs) with no history of disease. Procedures (methods): In a randomized control intervention, subjects will complete 5 different testing sessions (pre-screening, 2 baseline testing sessions, and 2 post testing sessions) as well as an 8 week intervention period. Pre-screening will include written informed consent, health history questionnaire, nutrition analysis, and baseline anthropometric measures. Baseline testing will be split into two sessions and include measurements of resting metabolic rate (RMR), body composition, blood and saliva hormones, mood, satiety, and health related quality of life questionnaires, and a cardiorespiratory fitness assessment. Subjects will be randomly assigned to treatment (8 week supplementation with meal replacement to be taken at breakfast) and control groups (continue normal eating habits) with 4 electronic correspondences throughout the supplementation period. All measures will be repeated in two post-testing sessions.
The purpose of this study is to evaluate whether a behavioral weight loss group in conjunction with a prescribed breakfast can help children between 8 and 12 years of age change their behaviors to help them lose weight and become healthier.
Contrary to popular belief, previous studies have demonstrated beneficial effects of whole egg consumption in modifying biomarkers indicative of a greater risk of coronary heart disease (CHD), chronic inflammation, and insulin resistance. The following study is designed to conduct a comprehensive evaluation of consuming an egg-based breakfast compared to an oatmeal-based breakfast on lipid biomarkers, oxidative stress, inflammation, insulin sensitivity, and satiety in young, healthy men and women. The investigators hypothesize that the consumption of 2 eggs per day will not negatively impact plasma lipids in a young, healthy population.
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.
One important factor determining school performance is the consumption of breakfast. While research has shown that older children perform better in school after consuming breakfast, there are little data for preschool-age children. Consuming breakfasts with different macro- and micronutrient contents may have different effects on performance, which may be associated with variations in satiation and satiety during and after the different breakfasts. In addition, children who consume breakfast have better diet quality than children who skip breakfast. The investigators will conduct a community based, randomized, crossover trial in 4-5 year old children over 7 weeks to examine the short-term effect of feeding preschoolers three different intervention breakfast types: high protein, high-fiber, or high protein and high fiber compared to a usual breakfast served at the preschool. The investigators expect that the children consuming any of the three experimental breakfasts will consume less overall calories and have better diet quality and memory performance compared to children who have the usual breakfast. The investigators hypothesis is that preschoolers will experience the highest level of satiety as well as highest level of overall diet quality when they consume the combined high-protein and high-fiber based breakfast foods. This study will be conducted at Bauer Family Resources in Lafayette as these are the sites of Head Start programs, which are preschools for children from low-income families. Children from families of low income are more likely to have poor diet quality and poor school performance compared to children from families with higher incomes. Therefore, this population is most in need of this type of intervention.
The purpose of this study is to test the hypothesis that the disruption of the "normal" (three meals a day) eating pattern and prolonged overnight fasting caused by skipping breakfast: i) alters the expression of specific clock genes and clock gene targets involved in regulating adipose tissue lipolysis (breakdown or destruction); ii) increases basal adipose tissue lipolytic (breakdown) activity and plasma free fatty acid (FFA) concentrations; iii) reduces skeletal muscle insulin sensitivity; and iv) increases daylong plasma glucose, FFA, and insulin concentrations. The investigator will do this by studying healthy, lean persons either randomized to consume either 3 standard meals per day or omit breakfast and consume 2 meals per day without changing daily calorie intake (skipping breakfast group).
The goals of this intervention study are to implement best practice strategies to expand and promote the school breakfast program and test the impact upon student participation rates among a) all 10th and 11th grade students and among a randomly selected cohort of 800 students b) total diet and body mass index and percent body fat inin 16 rural Minnesota school districts. School-wide Primary Aim: Improve participation in the school breakfast program among high school students. Hypothesis: School-wide school breakfast program participation will be higher in the intervention versus comparison group.
This study is designed to examine healthy children who skip breakfast and the effects of fasting on their neuropsychological functioning and the potential benefits that a Balanced Breakfast may have on their learning abilities. It is expected that this study will provide new knowledge on how prolonged periods of 8 or more hours without food affect neurocognitive processes and thus learning how specific meals following this period of fasting, which most children experience, change those processes, potentially for the better. The hypotheses for this study are: 1. Children who consume breakfast will demonstrate significantly higher levels of attention, greater concentration, and diminished impulsivity compared to children who do not consume breakfast. 2. Children who consume breakfast will demonstrate a significantly quicker reaction time and increased accuracy in correctly identifying target stimuli from an array compared to children who do not consume breakfast. 3. Children who consume breakfast will demonstrate increased freedom from distractibility and enhanced short-term memory compared to children who do not consume breakfast. 4. Children who consume breakfast will demonstrate increased cognitive processing speed compared to children who do not consume breakfast. 5. Children who consume breakfast will have improved verbal learning compared to children who do not consume breakfast. 6. Children who consume breakfast will have improved visual memory compared to children who do not consume breakfast.
