Although multiple studies have examined the effects of carbohydrate-restrictive diets, their safety in the long term is still heavily debated. Moreover, the dietary restraint theory states that there is alteration in the way food is regulated, switching from physiological to cognitive control; this change makes individuals more susceptible to disinhibited eating. Furthermore, carbohydrates, such as fruits, grains, legumes, etc., are the primary sources of energy that our bodies require during moderate to intense exercise. That being said, their involvement in our diet in crucial, as they grant us the ability to perform and function more efficiently. This study will investigate perceived physical (weight gain), mental (stress, body dissatisfaction), behavioral (binge eating) changes of individuals who had a carbohydrate restrictive diet for two weeks in the last year. The survey will be developed based on previous literature and have been validated in prior research. The binge eating and overeating scale is adopted from the American Psychiatric Association’s binge-eating scale (2013). The perceived stress scale is adopted from Cohen and Williamson’s Perceived Stress scale. Finally, the body dissatisfaction scale is adopted from Gideon et al.’s eating disorder examination questionnaire (2018). All of them will be measured as a multi-item scale, ranging from either strongly disagree (1) and strongly agree (5) or never (1) to very often (5). Questions such as gender, age, income, education level, and ethnicity are included. The participants will be asked to report their weight and height. Body Mass Index (BMI) will be calculated as weight (kg) divided by height squared (m2) to their BMI categories. The survey will be distributed via Amazon Mechanical Turk and is expected to be completed by 500 participants. Amazon Mechanical Turk (AMT) is a crowd-sourcing Internet marketplace enabling individuals and business to coordinate the use of human intelligence. AMT is strategically chosen for this study because of its ability to recruit a large number of subjects that is more representative of the U.S. population than in-person convenience samples. Theoretically, the completion of the proposed study will add novel literature to the nutrition research field. Practically, at the completion of this study, we will propose strategies and approaches about restrictive diets, post-diet weight gain, stress, and body dissatisfaction. Furthermore, we also hope that the research findings will give nutrition literature an area to touch on regarding the education, training, and research.
