The purpose of this study is to gather information about what family mealtimes look like for families with children between the ages of 3 and 8. Families will be asked to video record their family mealtime, in addition to answer some questions and to complete some questionnaires, some about body image and dieting.

On one occasion, your family's mealtime will be recorded via Zoom. You and your family will be asked some questions and to complete some questionnaires online.

To examine women’s self-reported pregnancy hydration behaviors, especially during a global pandemic. This study will also examine other lifestyle behaviors (e.g., weight gain, exercise, eating behaviors, sleep, pain management). It is hypothesized that hydration behaviors will decrease due to lifestyle changes related to the pandemic. Secondary outcomes will also be influenced by hydration behaviors and pandemic lifestyle changes.

The purpose of this feeding study is to examine if there is a difference in the effect of feeding a very low carbohydrate diet to people with normal weight and people with obesity. Participants will be asked to eat a very low carbohydrate diet, also known as a ketogenic diet, for 28 days. This diet will be provided to participants and includes 3 meals, some snacks, and beverages daily. Measurements of blood markers (fats, sugar, insulin, cholesterol), blood pressure, heart health, and body composition will be done at the start and end of the study.

In this study, you will be asked to consume a ketogenic diet for 28 days. This diet will be provided to you and includes 3 meals, some snacks, and beverages daily. This diet will meet your energy and nutrient needs. You will be asked to not eat any foods outside of what is provided by the study and consume no alcohol. Testing will be conducted on two consecutive days at the start of the study and the end of the study (a total of 4 testing days). For these visits, you will need to fast for 12 hours prior and avoid alcohol for 48 hours prior. At these visits, we will take a blood draw, measure your body weight, body composition, and preform non-invasive tests to assess your heart health.

There is a growing body of data demonstrating that polyphenols from foods including cocoa and chocolate are metabolized by the gut microbiome to produce small molecular weight metabolites that have greater systemic bioavailability and a potential role in the health-related effects of the parent compounds. The objective of this protocol is to collect fecal samples from human subjects, aged 18 - 40 years old, with overweight or obesity (BMI = 25 – 40 kg/m2), to use as a source of gut microbiota. These fecal samples will be used in in vitro fermentation experiments where fecal samples will be mixed cocoa powder or cocoa extracts in buffer. Samples from these fermentation experiments will be analyzed by chemical methods to identify the metabolites present and will be tested in bioassays to determine potential health-related bioactivities. Because biological sex can impact the composition of the microbiome, we plan to recruit both biological males and females.

There will be two in-person visits. Screening and consent collection will be done at the first and participants will receive supplies for stool collection. The participant will collect the stool samples at home and then return the sample at the second visit.

The purpose of this study is to examine how individual differences in interoception (the ability to sense, interpret, and act on bodily feelings like hunger, fullness, thirst, hot, cold, etc.) relate to eating behaviors in children ages 7-10 years. Findings will inform whether interventions targeting interoceptive awareness may be helpful for prevention of obesity and related chronic diseases.

Child and parent will attend 2 visits at the Clinical Research Center, about 1-3 weeks apart.At visit 1 (~3 hours)- Your child's height and weight will be measured- Your child's percent body fat will be measured using an x-ray based technology- Your child will wear a heart rate monitor and will complete tasks where they are asked to notice or count their heartbeat- Your child will complete questionnaires via an interview with a researcher- Your child will be asked to drink several glasses of water to measure their stomach sensations- You will complete questionnairesAt visit 2 (~2.5 hours)- We will collect 4 saliva samples from your child- Your child will eat a meal and taste snacks- Your child will play brain games on an iPad- You will complete questionnaires

This will be a 12-week single blinded, randomized, nutrition clinical trial for children with new diagnosis of stage 3 type 1 diabetes (clinical diagnosis of T1D). Beta cell function will be measured after 3 and 6 months.

Study participants in the intervention group will be required to follow the intake of specific foods and adhere to specific nutrition guidelines in addition to follow with a registered dietitian for 12 weeks (4 in person visits and 3 virtual visits). All these visits will be compensated. All study visits will be seen for a screening visit, an enrollment visit, 12-week visit and a 24-week visit. During the study visits, participants will undergo the following: physical exam/ demographic/social evaluation, clinical nutrition evaluation, nutrition counseling, dietary intake assessment, blood test collection, 2-hour Mixed Meal Tolerance Test (MMTT) and anthropometry.

This study uses virtual reality to investigate how sensory aspects of an environment influence eating behavior. Specifically, subjects will be immersed in a virtual outdoor café environment and consume a standardized meal while being exposed to either a pleasant or unpleasant smell. Total food intake and mood will be measured following each visit.

Answer initial screening and demographics questionnaires. Two in-person visits to the lab to experience a VR setting and consume a provided meal. One visit will include a small hair sample. Answer questionnaires following the VR experience.

The purpose of this study is to determine whether girls and boys regulate their appetites differently. Children will attend 1, 3 hour session in the laboratory, complete some surveys and health measures, donate saliva, and eat pizza.

Children will come to the lab for a 3.5 hour session where they will wear a heart rate monitor, conduct some surveys, have their veggie intake measured, provide some saliva, and eat some pizza. Parents will attend the lab visit with the child and complete questionnaires about feeding and the home environment.
