Dietary Behaviour Change Intervention Among Older People With Sarcopenic Obesity

The intervention consists of dietary guidance and behaviour change techniques, which will last for 15 weeks. The experimental group will be required to adhere to a diet consisting of a 12% reduction in calorie and a 1.2-1.5 g/kg body weight/day intake of protein. The participants will receive the dietary behaviour change guidance in 6 times face-to-face meetings and weekly telephone calls. They will also be asked to take daily food diary.

The control group will not be required any dietary changes. The investigator will contact with the control group with the same frequency and numbers of experimental group. But the chat topic will not be related to sarcopenic obesity or dietary guidance.
