7. Study Summary
Lay Summary | 1. Purpose of Study ○ Analysis of food management effects of the food management application ○ Analysis of weight loss effects of food management application ○ Identify the effects of food management application on blood metabolites 2. Research Background ○ According to the 2016 Community Health Survey conducted by the Korea Centers for Disease Control and Prevention, the health life of local residents related to the occurrence of major chronic diseases such as cancer, cardiovascular disease and chronic obstructive pulmonary disease has not been improved overall. In particular, the rate of attempted weight control has been increasing since 2008, while the rate of obesity has been steadily increasing. ○ The World Health Organization (WHO) has identified unhealthy diets, smoking, and lack of exercise as major risk factors for chronic diseases such as heart disease, stroke, cancer, chronic lung disease, and diabetes. More specifically, it is recommended that specific dietary patterns, such as increased food intake, can increase the risk of chronic disease and therefore follow detailed Dietary Guidelines by specifying detailed dietary factors such as high salt intake and trans-fat intake. Healthy eating habits and exercise alone can greatly reduce the risk of developing diabetes. ○ Intervention studies have been actively conducted to change the dietary habits and exercise behaviors of research participants using smartphone applications. Most of them include goal setting, action input and monitoring, and immediate feedback function. Through the monitoring function, the participant enters his or her usual eating behavior and automatically analyzes the nutritional data within the system, so that the researcher can more easily investigate the information on the nutritional intake. ○ 51 students who were overweight or obese (BMI≥24 kg/㎡), aged 18-35, were randomly assigned to one of two experimental groups: one to control weight using an application and the other to control daily weight. The average BMI of the application-use group was reduced by 1.6±2.6 kg/㎡, but no significant difference was found in the control group. ○ Metabolomics is one of the fields of biology that analyzes metabolism of cells and tissues and studies metabolic circuits accordingly. Metabolites are substances that are produced in processes such as energy production and storage, signal transduction, etc. of cells. In addition to being produced directly by host organisms, metabolites may be derived from microorganisms, foreign matter, dietary and other exogenous sources. ○ A total of 91 obese adults underwent a 1-year non-surgical weight loss program and analyzed the difference in serum metabolites from 137 before and after weight loss. The mean BMI of the subjects was decreased from 42.7±5.8kg/㎡ to 36.3±6.6kg/㎡ and about 58 kinds of metabolites were different before and after weight loss. Among them, amino acids associated with the onset of type 2 diabetes, such as isoleucine, leucine, valine, and tyrosine, were found to show differences between before and after weight loss. 3. Outline of research method This study will analyze the food and nutrient intake of each person and group through the diet record entered by the user using the food management application "Noom Coach" or the diet record notes, and compare the application group with the diet record note group to evaluate the effect of eating habits and weight loss. We will also analyze changes in blood metabolites before and after weight loss in the use of application and diet record note. |

Study Purpose | Prevention |
Phase | Not applicable |
Intervention Model | Parallel |
Blinding/Masking | Open |
Allocation | RCT |
Intervention Type | Behavioral |
Intervention Description | Sixty obese adults (BMI 25 kg/㎡ or more) with a willingness to weight loss were randomly assigned to the experimental group using the food management application and the control group using the diet record notes. The experimental group used the food management application "Noom Coach" and the control group used the diet record notes to record their meals freely for 3 months. Considering the possibility that the target energy intake setting function of the food management application significantly increases the participation intention of the experimental group, the control group before the start of the study is also provided with the dietary management leaflet to calculate the energy requirement for each participants and set the target energy intake box. |

Target Number of Participant 30 |
|
Arm Type Experimental |
|
Arm Description Of the sixty obese adults (BMI 25 kg/㎡ or more), 30 participants assigned to the experimental group through the stratified randomization method will record their meals for 3 months using the food management application "Noom Coach". Application "Noom Coach" has automatic calculation of calorie and nutrients during meal recording. |

Arm 2 |
Arm Label diet record note group |
Target Number of Participant 30 |
|
Arm Type Active comparator |
|
Arm Description Of the sixty obese adults (BMI 25 kg/㎡ or more), 30 participants assigned to the control group through the stratified randomization method will recorded their meals for 3 months using the diet record notes. Participants should calculate the daily total calorie intake by using Ministry of Food and Drug Safety's Food Safety Agency or Rural Development Administration agro-food comprehensive information system when recording food. It is expected that the increases of the participation intention among the food management application group due to the target calorie intake setting function of “Noom Coach”, the researcher will calculate the target calorie intake and report it to diet record note group. |
