The goal of this clinical trial is to how supplementation with beta -glucan during two days of caloric and carbohydrate restriction impacts subjective appetite and gastrointestinal appetite hormones in healthy overweight adults. In addition, the study aims to investigate the impact on gastric emptying since appetite and energy intake following food or supplement consumption can also relate to their impact on gastric emptying and as reduced hunger and enhanced satiety have been reported to be linked with delayed gastric emptying. The study will also investigate how these interactions impact after meal responses of insulin and glucose and thus insulin sensitivity. The caloric restriction during breakfasts and dinners will be achieved by low-calorie ready meals in the format of the counterweight PRO800 diet and lunches will be low in carbohydrates. It aims to test whether the addition of β-glucan to calorie and carbohydrate-restricted meals amends postprandial responses of appetite hormones and subjective appetite. participated will be assigned in double-blinded randomised crossover study, intervention group will be supplemented with 3g beta-glucan and the control group supplemented with 3g placebo.
The objective of this study is to assess the effects of Hass Avocados on glycemic control. The investigators hypothesize that Hass Avocado consumption will reduce fasting blood sugar compared to an isocaloric amount of other fruit during controlled feeding.
The bioactive compounds contained in tree nuts have been shown to beneficially affect cardiometabolic health outcomes. Pecans contain more total phenols, sterols, and flavonoids than any other tree nut. They also are a rich source of polyunsaturated fatty acids (PUFAs), fiber, vitamin A, vitamin E, folic acid, calcium, magnesium, phosphorus, potassium, and zinc. These bioactive components in pecans are likely the reason for the previously documented improvements in cardiometabolic health. The specific aims of this study are to: - Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on fasting and postprandial blood lipids. - Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on plasma markers associated with overall health. - Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on subjective and physiologic postprandial measures of hunger and satiety. Participants will be asked to: - Consume pecans daily for 28 days or maintain their current habitual diet. - Attend three short weekly visits for fasting blood craws, body measurements, and collect their next week's supply of study materials. - Attend two longer (5 h) testing visits which include consuming a standard breakfast meal and having their blood drawn periodically before and after breakfast. Researchers will compare pecan LOW, pecan MID, pecan HIGH, and the Control group to examine the physiologic effects of incorporating various dosages of pecans into one's diet.
The overall goal is to examine the efficacy of a circadian intervention in people with overweight and obesity and habitual short sleep duration (HSSD). Participants will undergo a randomized controlled trial, with circadian intervention and control (healthy lifestyle) groups. The circadian intervention is designed to reduce nighttime light exposure and after-dinner snack food intake. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).
The main objective is to measure the effects of intense brief exercise program in the workplace of administrative staff on the cardio-metabolic health
In humans, prolonged alterations in the circadian rhythm have been linked to cognitive impairments, premature ageing, and oncological and metabolic disorders such as diabetes and obesity. Obesity, in particular, is an ever-increasing condition with innumerable deleterious effects on human health. In recent years, studies have shown a relationship between a person's chronotype (morning or evening) and eating habits, as well as the importance of adapting these habits to physiological rhythms. Furthermore, it has been suggested that customising the caloric distribution of meals according to personal circadian rhythms may influence body weight and be one of the strategies to control overweight and obesity. In spite of the strong interest in this topic and the increasing number of observational studies conducted, there is currently a lack of intervention studies evaluating whether a low-calorie diet that takes into account the individual chronotype may be more effective than a standard low-calorie diet in the treatment of overweight and/or obesity.
The goal of this clinical trial is to learn about the effects of avocado consumption on gastrointestinal health in adults with overweight and obesity. The main questions is aims to answer are: How does avocado consumption affect the gut microbiome? How does avocado consumption affect thinking? Are there connections between the microbiome and cognition? Participants will be asked to eat provided meals with and without avocados for three 4-week periods. At the end of each 4-week period, participants will be asked to provide stool samples and complete computer games that assess thinking and memory.
In a randomised, controlled cross-over manner, this trial aims to determine how short-term daily supplementation with a milk fat globule membrane-enriched ingredient impacts on cardiometabolic health and cognitive outcomes.
The purpose of this research is to test if playing games designed to improve an individual's executive function can change their views about the types of foods they eat. Executive function is a set of mental processes that people use every day to make decisions - such as what kinds of foods they choose to eat and when and where they eat those foods.
