Fasting is being used as a therapeutic and cultural practice for millennia. There are numerous reports available on beneficial effects of fasting on various disease conditions. Despite the mounting evidence on fasting, little is known on its physiological effects in humans as most of the studies on physiological effects are done in animals.
Twenty healthy female volunteers (mean age ± SD, 21.95 ± 2.52 years) participated in a 10-day fasting program, which has 1 preparatory day and 1 refeeding day (1,000 kcal) and 8 fasting days (500 kcal). All the participants consented to participate in the study. Blood parameters like complete blood count, renal function test, total iron binding capacity, lipid profile, liver profile, vitamins D and B12, thyroid function tests, glycated hemoglobin, and air blood gas test along with anthropometric measurements were taken on the first and last day.
All the parameters under the study have shown statistically significant changes (p < 0.05) except hemoglobin (p = 0.7) and non-high density lipoprotein (p = 0.32). Notable changes were the significant increase in vitamins D and B12 levels that signifies the homoeostatic potential of a fasting regimen.
The result depicts the positive impact of fasting on various physiological parameters that warrants further studies on the safety of fasting in diverse diseases, especially the ones that have metabolic disarray as the root cause. Despite the limitation of the smaller sample size and lack of a control group, the results are encouraging to devise disease-specific fasting programs.
禁食作为一种治疗方法和文化习俗已沿用了数千年。关于禁食对各种疾病状况的有益影响,已有大量报道。尽管禁食的证据越来越多,但对其在人体中的生理影响却知之甚少,因为大多数关于生理影响的研究都是在动物身上进行的。
20名健康女性志愿者(平均年龄±标准差,21.95±2.52岁)参加了一项为期10天的禁食计划,该计划包括1天准备期、1天复食期(1000千卡)和8天禁食期(500千卡)。所有参与者均同意参与该研究。在第一天和最后一天进行了全血细胞计数、肾功能测试、总铁结合力、血脂谱、肝功能、维生素D和B12、甲状腺功能测试、糖化血红蛋白和动脉血气测试等血液参数以及人体测量。
除血红蛋白(p = 0.7)和非高密度脂蛋白(p = 0.32)外,研究中的所有参数均显示出统计学上的显著变化(p < 0.05)。显著变化是维生素D和B12水平的显著升高,这表明禁食方案的稳态潜力。
结果表明禁食对各种生理参数有积极影响,这值得进一步研究禁食在各种疾病中的安全性,尤其是那些以代谢紊乱为根本原因的疾病。尽管样本量较小且缺乏对照组存在局限性,但这些结果对于制定针对特定疾病的禁食方案是令人鼓舞的。
