简要总结
This randomized clinical trial will evaluate the efficacy and safety of protein supplemented very low calorie meals on weight loss and weight loss maintenance among people with obesity.
详细描述
Approximately 30% of the Korean population has obesity or abdominal obesity and is often accompanied by obesity related complications such as cardiovascular disease, diabetes, osteoarthritis and even some types of cancer. However, there are not many lifestyle modification treatments available that have long-term effects other than drugs and surgical treatments in the management of obesity.
Preserving muscle mass should also be considered in weight loss especially for elderly adults with obesity, because decreased muscle mass and strength can negatively affect morbidity and mortality in the elderly.
Therefore, the investigators want to evaluate the effectiveness and safety of the protein supplemented very low calorie meals on weight loss, body composition as well as metabolic changes compared with traditional low calorie low fat diet in people with obesity.

研究组 & 干预措施
Protein supplemented very low calorie diet program
The lifestyle intervention using protein supplemented very low calorie meals will be implemented with individual counseling sessions for 12 months. Initial intensive weight loss stage will be delivered during the first 4 month period with total meal replacement to partial meal replacement using protein supplemented very low calorie meals. During the weight loss maintenance stage, regular intermittent very low calorie meal replacement one week per month will be delivered for the entire period. Mobile counseling will be offered to help patients achieve weight loss as well as weight loss maintenance.
干预措施: Protein supplemented very low calorie diet program (Other)
Conventional low calorie diet program
The conventional low calorie diet program will be offered to participants assigned to control group using educational material and individual counseling sessions for 12 months. Mobile counseling will be also offered for weight loss and weight loss maintenance.
