The Effectiveness on an Application-Based Lifestyle Change Program on Health in Women

The purpose of this study will be to examine the effectiveness of an application-based lifestyle change program on body composition, body shape, body, image, and self-esteem in females following a 6-week period. The study will be carried out in a randomized, placebo-controlled, parallel manner. Participants will be stratified into quartiles based on their body mass indices during screening and prior to baseline testing. Participants from each quartile will be randomly divided by into experimental or control conditions.

Following randomization, participants will be baseline assessed on their body composition using a whole body Dual Energy X-Ray Absorptiometry scan, on their subjective measures of body shape and image using a variety of questionnaires, blood chemistry panel, and lower-body strength using a isometric mid-thigh pull dynamometer. Following baseline testing, participants will undergo 6-weeks of following their respective condition. Participants will be instructed to follow their group-specific guidelines for the 6-week period to the best of their ability. Body shape and image questionnaires and assessments of body composition, blood chemistry, and lower-body strength will be conducted following the week 6 to conclude the study.
