Change of Adipose Tissues and Triglyceride After Bariatric Surgery or Life-style Intervention

The study is aimed * To quantify the change of adipose tissues, triglyceride in liver and pancreas and cholesterol after lifestyle intervention or bariatric surgery. * To test the hypothesis that Brown fat is an independent biomarker for the development of Non Alcoholic Fat Liver Disease (NAFLD) * To study the association among Brown fat, NAFLD and obesity.

About this study

Interventions

Procedure: Bariatric surgery — Use of the normal bariatric surgery procedures commonly conducted in our hospital, such as: Laparoscopic Roux-en-Y gastric bypass (RYGB) and Laparoscopic sleeve gastrectomy (LSG)
Behavioral: Dietitian led life style modification intervention — Intensive 6 months life style changes supervised by diatitians.
Behavioral: Conventional care (control) — receive routine care

Primary outcomes

Use of modified Dixon Magnetic Resonance Imaging method to measure the response of adipose tissue in different organs following life style modification program or Bariatric surgery (one year)
Use of modified Dixon Magnetic Resonance Imaging method to measure the response of adipose tissue in different organs following life style modification program or Bariatric surgery 2 (one year)
Use of modified Dixon Magnetic Resonance Imaging method to measure the response of adipose tissue in different organs following life style modification program or Bariatric surgery- 3 (one year)
Use of modified Dixon Magnetic Resonance Imaging method to measure the response of adipose tissue in different organs following life style modification program or Bariatric surgery- 4 (one year)
Use of modified Dixon Magnetic Resonance Imaging method to assess the relationship between Brown Adipose Tissue and Non Alcoholic Fatty Liver Disease (one year)
Blood biochemistry for assessing β-cell function and insulin resistance (IR) (one year)
Blood biochemistry- 1 (one year)
Blood biochemistry- 2 (one year)
