Overview
Brief Summary
The goal of this pilot intervention is to learn about how a well-formulated ketogenic diet (WFKD) impacts various health factors in generally healthy adults. The main questions it aims to answer are:
- Establish whether an 8-week isocaloric, WFKD improves body composition and metabolic biomarkers in adults without chronic disease.
- Examine changes in transcriptomic sequencing pathways pre- and post-WFKD intervention.
- Explore gut microbial changes in adults without chronic disease that consume a WFKD.
Participants will follow a well-formulated ketogenic diet for 8-weeks. Study procedures include:
- Weekly body weight tracking
- Daily urinary ketone assessment
- Pre/post stool samples for gut microbiota analyses
- Pre/post DXA scans
- Diet quality tracking through 3-day food records
