treatment
脂肪肝治療 Treatment
  • 未有針對性的藥物治療。No specific treatment
  • “三低一高”的飲食原則: “3 low 1 high”Healthy Eating Principle
    • 減少脂肪、鹽份及糖類的攝取,多吃高纖維的食物。Reduce fat, salt and sugar intake. Increase fibre intake
  • 多運動,維持標準體重。Increase exercise, maintain healthy body weight
  • 同時患有糖尿病的病人,須加強血糖控制。Well control blood sugar level for diabetic patients
aim of study
研究目的Aim of Study
  • 測試低升糖指數飲食配合生活模式輔導對患有非酒精性脂肪肝病人的影響

To test the efficacy of a low-glycemic index dietary intervention programme in NAFLD patients

低升糖指數飲食配合生活模式輔導Content of Low GI Diet and Intensive Lifestyle Modification Programme
  • 病人經過隨機抽選,只有干預組病人能參與

Only subjects randomized in the intervention group will receive the low glycemic diet and intensive lifestyle modification programme (LMP)

what is gi
什麼是升糖指數 What is GI?
  • 升糖指數是用來量度進食食物後的 2 小時內,血糖水平上升幅度與參考食物(麵包或葡萄糖)比較的一個指標。

Glycemic Index is a standardized system of ranking foods based on their effect on blood glucose levels over 2 - 3 hours compared to a reference food (bread or glucose)

健康生活模式輔導The aim of LMP
  • 鼓勵長久生活習慣上的改變,從而減低熱量的吸收,增加熱量的消耗

The purpose of the program is to develop lifestyle behaviours that encourage increasing caloric expenditure while decreasing caloric intake, with an emphasis on long term lifestyle and behaviour change

  • 包括4個月的體重控制和8個月的體重維持期

4 months intensive follow-ups for weight loss and then 8 months monthly follow up for weight maintenance

  • LMP是香港中文大學營養研究中心結合過去的研究成果,再經臨床驗證的一項有效及健康的體重控制療程†。透過個人化的生活模式修正輔導,令參加者達到理想的體重。重獲健康的身心,更可增加他們對營養和健康的認識。

LMP is a healthy weight loss program established by the Centre for Nutritional Studies and its efficacy has been clinically proved†. It aims to help people to lose and stay a healthy weight as well as enhance their dietary, nutritional and health knowledge through an individualized tailor made lifestyle counseling.
