科学评估
可能错误 – 现有证据倾向于不支持该说法，但尚无定论。
证据确定性: 低 – 进一步研究很可能大幅改变该评估。
1. 说法是什么？
One meal a day and long daily fasting are the basic healthy eating pattern.
2. 哪些内容可证实是正确的？
Intermittent fasting, including shortened eating windows, helps some people eat less and lose weight about as well as ordinary calorie restriction (I-FAST-113, I-FAST-05, I-FAST-02, I-FAST-03). One meal a day reduced fat mass in a small trial (I-FAST-115).
3. 哪些内容是错误或夸大的？
No good evidence shows that one meal a day or eating every second day is 'the healthy way'. Compared with standard dietary advice, intermittent fasting made little to no difference to weight loss (I-FAST-114). One meal a day raised blood pressure, LDL cholesterol and hunger (I-FAST-115) and was associated with higher mortality in an observational study (I-FAST-116). Alternate-day fasting raised LDL and had high dropout (I-FAST-02); 16:8 without calorie targets lost lean mass (I-FAST-04). People on glucose-lowering drugs who skip meals have more severe hypoglycaemia (I-FAST-10).
4. 哪些内容仍不明确？
Long-term (multi-year) outcomes of one-meal-a-day patterns.
5. 哪些研究支持该说法？
I-FAST-113 and I-FAST-05 (IF works about as well as calorie restriction); I-FAST-03; partly I-FAST-115 (fat mass reduction) and I-FAST-02.
6. 哪些研究与该说法相矛盾？
I-FAST-114 (Cochrane 2026: no advantage over dietary advice), I-FAST-115 (BP, LDL, hunger up), I-FAST-116 (mortality association), I-FAST-04, I-FAST-07, I-FAST-10; partly I-FAST-02.
7. 对德国和欧洲而言情况如何？
DGE recommends regular, balanced meals but accepts different meal patterns; no recommendation for one meal a day (not fetched).
8. 关于埃及的已知情况是什么？
Ramadan provides a cultural model of daily fasting; IDF-DAR guidelines describe risks for people with diabetes (I-FAST-11).
9. 合理的实际结论是什么？
对于喜欢这种方式的健康成年人来说，缩短进食时间窗口是一种可接受的体重控制方法，与其他减少热量的方法相当，但并不是一条更优越或普遍适用的规则。使用糖尿病药物的人在改变进餐模式之前，必须与医生一起调整剂量。
评估详情
- 证据确定性的依据
Intermittent fasting gives little to no difference in weight loss vs regular dietary advice (Cochrane 2026, MD -0.33%, low certainty; I-FAST-114) and is about equal to continuous energy restriction (BMJ 2025 NMA of 99 RCTs; I-FAST-113). One meal a day at equal calories reduced fat mass but raised blood pressure, LDL cholesterol and hunger (I-FAST-115); in a US cohort, one meal a day was associated with higher all-cause (HR 1.30) and cardiovascular mortality (HR 1.83) (observational; I-FAST-116). Eating every second day has not been studied as a lifelong pattern. Certainty low because the specific pattern is rarely tested directly.

总体证据说明了什么？
基于上述研究的编辑评估——其本身并非研究结果。
哪种观点有更好的证据支持？
Intermittent fasting, including shortened eating windows, is an acceptable weight-loss option for healthy adults, roughly equal to ordinary calorie restriction or dietary advice. There is no evidence that one meal a day or eating every second day is 'the healthy way'; small trials show mixed effects (less fat but higher BP/LDL, more hunger) and an observational study links one meal a day to higher mortality.
为什么有些研究权重更大
Cochrane and BMJ NMA (high-quality syntheses) define the comparative effect; OMAD-specific evidence is small; mortality data are observational.
因果关系是否已确立？ 尚未确立 No trial with hard outcomes; observational mortality signal may be confounded.
仍存在的不确定性
Long-term effects of one meal a day; true every-other-day eating as a lifelong pattern.
合理的结论
A reasonable option for some healthy adults, not a superior or universal rule; unsafe without medication adjustment in diabetes.
为什么研究结果看起来互相矛盾？
BMJ NMA (slight ADF advantage) and Cochrane (no difference vs advice) differ in comparators and time frames: the ADF advantage appears only in short trials and against continuous energy restriction.
这是否取决于国家？

All individuals should break the fast if blood glucose <70 mg/dL (3.9 mmol/L) or >300 mg/dL (16.7 mmol/L) or with symptoms of hypoglycaemia or acute illness; people with T1DM are high/very high risk; during fasting glucose falls and insulin secretion is suppressed; when glycogen is depleted and insulin is low, fat is converted to ketones.

- 2026年10月26日 · 第 4 阶段（系统证据审查） · 评定结论已更改: 不明确 / 证据不足 (低) → 可能错误 (低)
The 2026 Cochrane review and the 2025 BMJ NMA now show no meaningful superiority of intermittent fasting over standard advice, and direct OMAD data show mixed or unfavourable effects. A claim that this is 'the healthy way' is therefore not supported; 'unclear' understated the consistency of the no-superiority finding. Certainty stays low because OMAD/every-other-day eating has hardly been studied directly.

通俗解释
在较短的时间窗口内进食或每天只吃一次，可以帮助一些人少吃并减重。大型综述表明，其效果与普通节食大致相当，并不更好。在一项小型试验中，每天只吃一餐使血压和LDL胆固醇升高；一项大型观察性研究还发现它与更高的死亡风险相关。每隔一天才吃东西的做法尚未得到充分研究。使用胰岛素或某些糖尿病口服药的人如果不吃饭，可能会出现危险的低血糖。
