Overweight and obesity are a global concern. Meal replacements (MRs) are portion- and calorie-controlled meals, which make the food environment part of an individual's weight loss regimen. White sweet potato (WSP; L.), used in traditional medicine in Brazil, Japan, and Taiwan, is a healthy carbohydrate source. In this randomized controlled trial, we assessed the effects of a WSP formula on body weight management in 58 white-collar workers through MR to elucidate the effects of this WSP-MR on factors leading to overweight. The participants consumed either two packs a day for a total of 132 g of WSP (WSP-MR group) or a normal diet daily (non-WSP group) for eight weeks. After eight weeks, body weight, body fat, body mass index, wrist circumference, thigh circumference, calf circumference, mid-arm circumference, and triceps skinfolds decreased significantly in both the groups. Moreover, the WSP-MR group demonstrated a 5% decrease in body weight, body fat, body mass index, and mid-arm circumference and a 3.5% decrease in glycated hemoglobin levels ( < 0.05). The treatment was well tolerated, without side effects or adverse events. Thus, our WSP formula as an MR can facilitate individual weight loss and thus has commercial application in the food industry.
超重和肥胖是一个全球性的问题。代餐（MR）是一种份量和热量控制的餐食，可以使食物环境成为个人减肥计划的一部分。白薯（WSP；L.）在巴西、日本和中国台湾被用于传统医学，是一种健康的碳水化合物来源。在这项随机对照试验中，我们通过 MR 评估了 WSP 配方对 58 名白领体重管理的影响，以阐明这种 WSP-MR 对导致超重的因素的影响。参与者连续八周每天食用两包，共 132 克 WSP（WSP-MR 组）或正常饮食（非 WSP 组）。八周后，两组的体重、体脂肪、体重指数、腕围、大腿围、小腿围、中臂围和三头肌皮褶厚度均显著下降。此外，WSP-MR 组的体重、体脂肪、体重指数和中臂围减少了 5%，糖化血红蛋白水平降低了 3.5%（<0.05）。该治疗耐受性良好，无副作用或不良反应。因此，我们的 WSP 配方作为一种 MR 可以促进个体减肥，因此在食品工业中有商业应用前景。
