Clinical Trial 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
