This study is being done to see how individuals respond to a ketone ester (KE) across different age groups and health statuses. With the ketogenic diet becoming more popular, research on ketones (a molecule created when fat is broken down in the body) has grown as well.
These findings will be used to help develop future research studies and help others to pick the right doses of ketone supplement.

Have NOT experienced >10% weight loss in the last 6 months
Do NOT currently consume a low carbohydrate diet
Do NOT consume alcohol more than 3 drinks/daily or 14 drinks/weekly
Do NOT suffer from food allergies or gastrointestinal disorders

- Age: 18 - 40 years old
- BMI: 20-35 kg/m2

This study is intended to evaluate the effects of different dosing measurements for different ketone products in healthy male adults. After giving consent to this study you will schedule 9 testing sessions about 3 days apart. During these sessions you will come into the Physical Activity and Education Services (PAES) building in the morning, having had no food that day and take a study product. Various tests will be administered after ingestion. You will have blood draws to tell us more about your metabolic response to the product.
- Have a BMI >18 kg/m2 or ≤29 kg/m2
- Do NOT smoke or have diabetes, liver disease, kidney disease, cardiovascular disease, or any form of endocrine dysfunction
- Do NOT currently consume a low carbohydrate diet
The purpose of this study is to learn about the associations of symptoms such as fatigue, depression, and gastrointestinal distress including constipation, abdominal pain, and diarrhea with stool microbiomes and metabolites in patients with colorectal cancer. We will compare the associations of symptoms with microbiomes among colorectal cancer patients and healthy patients. You will be asked to complete several surveys that ask questions about your dietary habits, your health history, your social demographics, and your symptoms. You will also be asked to collect a stool sample with an at-home stool sample collection kit that will be provided to you.

The purpose of this study is to lower the rate of type 2 diabetes in rural Appalachia youth due to obesity and/or being overweight. Our long-term goal is to improve the health of underserved, high-risk youth.
This study will test the effectiveness of the Mentored Planning to be Active + Family on physical activity outcomes and health outcomes among rural Appalachian middle school aged youth suffering from either overweight or obesity.
We have local high school-aged teen mentors work closely with middle school youth to increase social support, self-efficacy, and self-regulation skills to sustain physical activity and improve health before the children enter high school.
The peer mentoring is followed by a 6-month family reinforcement program.
Some parents will provide child assessment data of perceived child physical activity behaviors and child health.
- Child has access to a computer or tablet device at home for virtual mentoring sessions/meetings
- Child suffers from overweight or obesity - does not need to be under the care of a health care professional for this condition
- Child and Parent able to participate read English at a 4th grade level.
- Family not expected to move from rural Appalachia within the 18 months.
