Purpose:
To assess improvements in eating behaviors and health measures among adults participating in a whole food plant predominant diet, Full Plate Living (FPL) program.
Design:
Retrospective, post hoc analysis of self-reported 16-week pre-post participant data obtained over a 3 year program period (2017-19).
Setting:
Wellness offering for employees in Southwest U.S.
Subjects:
Of 6,820 enrollees, 4,477 completed the program, further segmented by generational cohorts.
Intervention:
FPL program materials and weekly online video lessons.
Measures:
Baseline and follow-up measures included eating behaviors, self-perceived health status and energy, body weight, and confidence in healthy eating and weight loss.
Analysis:
Paired t-tests were used to examine changes in eating behaviors and health measures. Mixed-effects models were used to examine whether changes among generational cohorts differed.
Results:
Significant pre-post improvements were demonstrated for all measures, including servings of fruits (1.54 to 2.34), vegetables (2.05 to 2.87), beans (.63 to .99), and weight loss (3.5) (P < .001). Self-perceived health and energy values, and confidence in making healthy food choices and losing weight improved (P < .001). Improvements were observed across generational cohorts (P < .001).
Conclusion:
The FPL healthy eating approach has a beneficial impact on health measures across generational cohorts, and may be an effective addition to lifestyle medicine and corporate wellness offerings. Longer-term program evaluation is warranted.
