摘要: | 過重與肥胖會增加罹患第二型糖尿病、高血壓、高血脂等疾病的風險,同時也會增加疾病死亡率。肥胖主要因能量代謝的失衡所導致,包括飲食上攝取過多熱量,或加上日常活動量不足、缺乏運動,使得熱量消耗太少。過去研究指出飲食熱量控制是減重的有效方法,而代餐又是當前熱門常見的飲食份量控制方式。植物性食物為主的飲食 (plant-based diet)經研究證實能藉由增加餐後代謝率、提高胰島素敏感性達到減重效果。然而,東方素食飲食中常見的素肉多使用黃豆、穀類等加工製成,熱量高營養價值低;為了增加食物口感使用油炸、勾芡、紅燒、淋醬等,皆為高油高糖、高熱量的烹調方式,這些皆為素食飲食仍可能造成過重與肥胖的原因。因此本研究透過給予過重或肥胖之素食者代餐減重連續8週,探討對於體重控制、血糖、血脂,以及生化代謝數值之影響。本研究招募過重或肥胖 (24 ?BMI<35 kg/m2)、年齡大於等於20歲之素食女性24位,隨機分為實驗組 (n=13)與對照組 (n=11),連續8週每日分別給予實驗組代餐1包 (熱量約170kcal)代替早餐,其他飲食照常;對照組提供一週早餐循環菜單 (熱量約150 kcal),其他飲食照常。於實驗前、後進行體位、身體組成、血壓及血液生化數值檢測。由本次研究結果發現,代餐之給予對於過重或肥胖素食成年女性於實驗後在體重、體脂肪量、血糖以及血脂有顯著降低的效果。 Overweight and obesity increase the risk of type 2 diabetes, hypertension, hyperlipidemia, and increase disease mortality. Obesity is mainly caused by an imbalance in energy metabolism, including excessive calorie intake from diet, along with insufficient daily activity and lack of exercise, leading to inadequate calorie expenditure. Previous studies have indicated that calorie control is an effective method for weight loss, and meal replacements are currently a popular and common way to control portion sizes. Plant-based diets have been shown to achieve weight loss by increasing postprandial metabolic rate and improving insulin sensitivity. However, the common of plant-based diets in Eastern cultures often include processed vegetarian meats, which are high in calorie and low in nutritional value. These diets often use cooking methods like frying, thickening, braising, and drizzling with sauces to enhance flavor, all of which are high in oil, sugar, and calorie. This study aims to investigate the effects of providing meal replacements for 8 consecutive weeks to overweight or obese vegetarians on weight control, blood glucose, blood lipids, and biochemical metabolism values. This study recruited 24 overweight or obese (24 ?BMI <35 kg/m?), vegetarian women aged 20 and above, randomly divided into an experimental group (n=13) and a control group (n=11). The experimental group was given 1 pack of meal replacement (approximately 170 kcal) per day to replace breakfast for 8 consecutive weeks, while other meals remained unchanged; the control group was provided with a 1-week breakfast cycle menu (approximately 150 kcal), with other meals remaining unchanged. Measurements of body weight, body composition, blood pressure, and blood biochemical values were conducted before and after the experiment. The results of this study found that providing meal replacements to overweight or obese adult vegetarian women significantly reduced body weight, body fat mass, blood sugar, and blood lipids after the experiment. |
