Brief summary
The objective of this study is to determine the impact of an integrated personalized dietary and wellness program which includes dietary advice, meals, and counseling on health and wellness.
Detailed description
The objective of this study is to determine the impact of an integrated personalized dietary and wellness program, which includes personalized dietary advice, meals, and behavior guidance, on markers of health and wellness, body composition, and psychosocial measures. Behavior questionnaires, motivational interviewing, psychosocial questionnaires, and participants' self-generated data on diet, preferences, activity, and sleep will be used in combination with anthropometric and biological data (fasted blood-based measures following an oral protein glucose lipid tolerance test \[liquid meal challenge test\], and selected single nucleotide polymorphisms) to create individualized, tailored dietary advice, meal and counseling plans.
