Filter by:Food prepared outside of the home tends to have a high energy content, and high levels of nutrients of concern (sodium, fat, saturated fat and sugar), especially when compared to home-cooked food. A number of studies suggest that when energy density of a food is manipulated it has a linear effect on energy intake, because consumers tend to eat a constant weight of food. However, recent observational research suggested that up to approximately 1.5-2kcal/g, individuals are relatively insensitive to changes in energy density, and there is no indication of compensation through altering meal size. However, upwards of approximately 1.5-2kcal/g, the authors proposed that individuals compensate for increases in energy density by selecting and consuming smaller meal sizes. The investigators aim to measure participant's consumption (in grams and kilocalories) of three meals at low, medium and high energy densities, and to measure later food intake to observe any evidence of later compensation in response to experimental condition
The purpose of this 4 week pilot study is to test the use of a mobile application (also commonly referred to as an app) designed to help increase self-management strategies among youth that have asthma and obesity. The data obtained from this study will facilitate refinement of the app and interventional approaches for a future larger scale study to increase youth self-management of their clinical conditions, symptom management, and health maintenance as they transition to adulthood.
Access to the vascular access is difficult in obese patients. Therefore, vascular access can be challenging and worrying for obese individuals. This strain causes pain and anxiety. Different interventions can be applied to reduce the pain and anxiety felt. One of them is the methods of distraction. Among these methods, chewing gum and using a stress ball can contribute positively to the pain and anxiety at the entrance to the vein in order to draw blood in obese individuals. In addition, these interventions may affect vital parameters. It was aimed to evaluate the effects of chewing gum and using a stress ball during vascular access in obese individuals on pain level, anxiety level and vital signs
The goal of this clinical study was to assess pharmacodynamics (PD) and pharmacokinetics (PK) of different Glucose beads formulations in obese healthy subjects under fasting condition. The study was designed in 2 parts. Part 1 (single-dose) of the study was randomized, open label, five-treatment, five-period, five-sequence, crossover and single-centric. Treatment arms were three dosages of a coated Glucose beads formulation (47% w/w glucose/bead; 8 g [T1], 12 g [T2] and 16 g glucose [T3]), one uncoated Glucose beads formulation (47% w/w glucose/bead; 12 g glucose [T4]) and one coated Glucose beads formulation (60% w/w glucose/bead;12 g glucose [T5]). Part 2 (multiple-dose) of the study was open label, one-treatment, one-period and single-centric. Treatment arm was coated Glucose beads formulation (12 g glucose [T2]).
This quasi-experimental study aims to determine the effectiveness of a health intervention (Chance2Act) on behaviour change to act for weight loss among overweight/obese type 2 diabetes adults. The main question it aims to answer is: - Is the new health intervention (Chance2Act) effective in changing overweight/obese type 2 diabetes adults from not being ready to act, to take action to lose weight?
The purpose of this study is to understand the personal flow along the weight loss management journey. A range of variables will be addressed in a survey to explore the weight loss journey, barriers and management. Topics include weight loss strategies and challenges, HCP involvement, and perceptions towards weight loss medications. Potential participants will be recruited using various online panels. Study participants will be recruited to participate in 2 types of qualitative research. Phase I: Online bulletin boards (OBB) Phase II: Virtual focus groups (real-time)
Previous studies in humans indicate that anthocyanin-rich berries can positively alter fat oxidation and insulin sensitivity. This study will determine if this is also true with elderberries, which are a more concentrated source of anthocyanins compared to other commonly consumed berries.
The goal of this pilot trial is to learn about the optimal intensity level of goals in a digital weight loss intervention among adults with overweight or obesity. The main questions of the study are to assess the feasibility and acceptability of different goal intensities across four domains (calorie goal, step goal, eating window goal, red zone food goal). The investigators will recruit 32 total participants to the trial. Recruitment will occur through remote channels. Interested individuals will be directed to an online screening questionnaire; those who are eligible will then be invited to attend an initial remote session with study personnel to ensure interest and eligibility in the study. The weight loss intervention will last 10 weeks, and all participants will receive a "core" treatment consisting of self-monitoring weight, food intake, and steps (all via digital tools provided by the study team), along with behavioral lessons, action plans, and tailored feedback. Depending on which group participants are assigned to in the study, individuals will receive either a more or less challenging goal across the four domains. All study tasks will occur remotely, thus, participants will never come in-person for any tasks. Assessment of body weight and other measures will occur at the beginning of the trial ("baseline"), and at 4 weeks and 10 weeks. The investigators will use the Multiphase Optimization Strategy (MOST) framework to identify which of the goal intensity levels result in meaningful engagement and weight loss. The current study is the first step towards answering this question; it is designed as a pilot factorial trial, which focuses on feasibility and acceptability. In total, there will be 16 treatment conditions.
People with obesity regularly experience discrimination on the basis of their body weight and such experiences are associated with increased risk for poor cardiovascular health. The goal of this clinical trial is to identify cognitive, affective, behavioral, and physiological factors that explain the relationship between weight discrimination and poor health outcomes. A diverse sample of adults with obesity will be randomly assigned to a social interaction encounter that simulates a typical weight discrimination experience (experimental manipulation) vs. a control manipulation that does not involve discrimination. The investigators will examine the immediate effects of the experimental manipulation on cognitive (e.g., self-regulation), affective (e.g., negative emotion), behavioral (e.g., comfort eating), and physiological (e.g., cortisol secretion) outcomes. Two additional aims of the study are to identify psychological traits that moderate responses to weight discrimination and to assess whether the negative health effects of weight discrimination differ by age, sex/gender, race, or ethnicity.
This single-dose, randomized, open label, five-treatment, five-period, five-sequence crossover study was performed to assess pharmacodynamics (PD) and pharmacokinetics (PK) of three new developed coated Glucose beads formulations (containing glucose (8 g) and caffeine), one coated Glucose beads formulation (containing glucose (8 g)) and one uncoated Glucose beads formulation (containing Glucose (8 g) and caffeine) after single-dose administration (fasting conditions) in 20 obese healthy subjects. After an overnight fasting of at least 10 hours the subjects were administered either glucose (8 g) or glucose (8 g) and caffeine starting at 8:00 (time 0; administration time was staggered beginning at 8:00 for the first group of subjects) in sitting position. At least 3 days wash-out period was kept between each treatment periods.
