Worldwide, obesity has nearly tripled since 1975 and has become a major healthcare challenge today. Intermittent fasting (IF) is gaining popularity as a weight loss strategy in recent times. This study aimed to study the role of IF as a modern-day weight-loss strategy in obese adults through a real-world pilot experiment conducted at a nutrition clinic in Mumbai.
To understand the effects of IF on weight loss, 32 overweight/obese [body mass index (BMI) ≥23 kg/m2] adults from a nutrition clinic in Mumbai, were assigned consecutively to an IF plan and followed up for 3 months. Their demographic, anthropometric, and dietary assessments were done pre- and post-intervention. Qualitative interviews were done at the end of the study to record the participants' overall well-being, experience, and sustainability of IF.
56% of study participants were males and their mean age was 35.6 ± 8.9 years. 65.6% of participants were able to maintain 14-16 hours of fasting and 53% managed all 7 days of IF. Analysis of post-intervention data showed a significant reduction in mean body weight (88.5 ± 19 to 83.8 ± 17.6 kg), waist circumference (M: 108.2 ± 11.3 to 103.6 ± 4.4 cm, F: 98.9 ± 8.8 to 93.3 ± 3.3 cm), BMI (31.4 ± 5.3 to 29.6 ± 5.1 kg/m2), daily calories (1782 ± 237 to 1388 ± 243 kcal/day), carbohydrate intake (267 ± 18.4 to 164 ± 4.0 g/day), and an increase in protein intake (39 ± 11 to 55 ± 11 g/day). Participants reported positive experiences of practicing IF such as improved fitness, sleep cycle, and adoption of healthy eating habits.
The study demonstrates that IF could aid in weight loss and adoption of a healthier lifestyle.
自 1975 年以来，全球肥胖率几乎翻了三倍，如今已成为主要的医疗保健挑战。间歇性禁食（IF）作为一种新的减肥策略近年来越来越受欢迎。本研究旨在通过在孟买的一家营养诊所进行的真实世界试点实验，研究 IF 作为一种现代减肥策略在肥胖成年人中的作用。
为了了解 IF 对减肥的影响，孟买营养诊所的 32 名超重/肥胖成年人（BMI≥23kg/m2）连续被分配到 IF 计划，并在 3 个月后进行随访。在干预前后对他们的人口统计学、人体测量学和饮食评估进行了评估。在研究结束时进行了定性访谈，以记录参与者的整体健康状况、经验和 IF 的可持续性。
研究参与者中有 56%为男性，平均年龄为 35.6±8.9 岁。65.6%的参与者能够保持 14-16 小时的禁食时间，53%的参与者能够在所有 7 天内进行 IF。干预后数据分析显示，平均体重（88.5±19 至 83.8±17.6kg）、腰围（M：108.2±11.3 至 103.6±4.4cm，F：98.9±8.8 至 93.3±3.3cm）、BMI（31.4±5.3 至 29.6±5.1kg/m2）、每日卡路里摄入量（1782±237 至 1388±243kcal/天）、碳水化合物摄入量（267±18.4 至 164±4.0g/天）和蛋白质摄入量（39±11 至 55±11g/天）均显著降低。参与者报告了实施 IF 的积极体验，如提高了健康水平、睡眠周期和养成了健康的饮食习惯。
该研究表明 IF 可以帮助减肥和养成更健康的生活方式。
