追加：早餐与进食时间一条 · 核实记录（2026-09-21）
任务来源：用户问「有没有关于要不要吃早饭，是按时吃饭还是饿了吃饭更好的内容」。
原有覆盖：全书搜「早饭」「早餐」「三餐」「按时吃」「断食」「禁食」「进食窗口」「限时」，只有第 28 节第 1 条（不要用极端节食、断食或催吐来控制体重）沾边，讲的是进食障碍，不回答「吃不吃早餐、几点吃」。第 29 节两处「三餐」说的是丧亲后有人盯着吃饭。本主题零覆盖。
落点：第 6 节第 26 条，追加在节末。放反面清单是因为要否掉的是两个流行说法（「吃早餐有助健康和控制体重」「16:8 轻断食比单纯少吃更管用」），而不是吃饭这件事本身。两个说法合成一条写，是因为它们是同一个错误的两面：都以为「什么时候吃」能脱离「吃了多少」单独起作用；拆成两条，读者容易只看一半，反而从「那我改成 16:8 试试」走掉。口径记死亡率（健康终点与体重）。

定级与取舍
- 2026-09-21 当天返工（用户指出两处问题）：初稿标题写成「不要为了健康逼自己吃早餐，也不要指望 16:8 轻断食比单纯少吃更管用」，说人话开头是「『吃早餐有助于控制体重』是反的」。用户的原话是「正常人看，吃早餐更胖是正常的吧，长期不吃早餐有没有危害这个也没写」。两处都成立：① 靶子写丢了。「吃早餐的人体重更高」对读者不反常识，多吃一顿当然多摄入；BMJ 那篇真正否掉的是流行说法「不吃早餐会让人午饭晚饭暴食、一天总量反而更多」，关键数字是不吃早餐那组一天总摄入低 259.79 kcal，也就是没补回来。已把说人话和收益栏都改成先立这个靶子，并把摄入那一项提到体重前面。② 「长期不吃早餐有没有危害」是读者的核心问题，初稿把它整段放在备注里，而按全书规矩说人话只能用收益栏里的东西，那句话没法写进最显眼的位置。已把观察性那两篇（Zhang 2025、Rong 2019）从备注移进收益栏和来源栏，备注只留混杂解释。标题同时改成「不要指望吃早餐或 16:8 轻断食帮你控制体重，吃饭时间挑你能长期坚持的」，第 2 节第 34 条的互指锚点跟着改。收益栏因此变成「三段式」：先驳流行说法，再看 16:8，最后回答长期危害。
- 2026-09-21 第二次返工（用户举了两个民间说法）：用户原话是「我看网上说不吃早餐肠子会消化屎，相当于吃屎，还有人说对胃不好」。查证结果：① 「肠子消化粪便」在文献里查不到任何对应机制。结肠回收水和电解质是恒定的正常生理，与是否吃早餐无关，粪便不会被当作食物吸收。这个说法不写进正文——全书不做「辟谣式」条目（见写作规则：条目写给读者，不是回应提问的人），正面陈述该查什么即可。② 「对胃不好」半真半假，真的那半不在胃上而在胆囊，已补进备注（见下表两篇）。同时把备注原来那句「两边合起来看，吃饭时间的影响很小，别为它花心力」判为说过头了：心血管、胆结石、消化道癌三条独立的观察性证据都指向同一方向，虽然都不能证明因果，但不该用一句「影响很小」盖过去。已改成分开说——就控制体重而言影响很小；长期完全不吃早餐好不好只有关联证据，方向一致偏不利，想稳妥就正常吃，只是别指望它减重。说人话末句的「但总死亡率看不出差别」改成「总死亡率则看不出差别」，去掉那个读起来像安抚的「但」。
- 本轮新增的两篇（都放备注，不进收益栏）：
- https://doi.org/10.3389/fnut.2024.1521707（Sun T, Zhang L, Lu Y, 等. Front Nutr 2024;11:1521707，PMID 39737153）。原文：「A total of 6,547 participants were included. The fully adjusted model indicated a positive correlation between the FMT of the day and the prevalence of gallstones (odds ratio [OR] = 1.05, 95% confidence interval [CI] = 1.02–1.08)」「The risk of developing gallstones was the greatest when the FMT was between 09:00 and 14:00 (OR [95% CI] = 1.49 [1.24–1.77])」。FMT = first meal time。是横断面调查，不能定因果方向，备注里写明了可能是先有胆囊问题才改的吃饭习惯。
- https://doi.org/10.1007/s11606-023-08094-7（Liu T, Wang Y, Wang X, 等. J Gen Intern Med 2023，PMID 36869181，开滦队列 ChiCTR-TNRC-11001489）。原文：「During a median follow-up of 5.61 (5.18–6.08) years, 369 incident GI cancer cases were identified.」「Participants who did not eat breakfast had an elevated risk of esophageal (HR = 2.72, 95% CI: 1.05-7.03), colorectal (HR = 2.32, 95% CI: 1.34-4.01), liver (HR = 2.41, 95% CI: 1.23-4.71), gallbladder, and extrahepatic bile duct cancer (HR = 5.43, 95% CI: 1.34-21.93).」备注只引结直肠和胆囊胆管两项，并把 1.34–21.93 这个区间原样写出来，让读者自己看出事件太少。
- 查了但没写进去的：https://doi.org/10.1186/s41043-025-01223-4（Ostadsharif N 等, J Health Popul Nutr 2026，PMID 41527009），11 项研究 21,220 人的荟萃，「higher meal frequency was associated with a reduced risk of FD (n = 2, OR = 0.52, 95% CI: 0.32-0.86)」。只有 2 项研究支撑这一项，且 FD（功能性消化不良）是症状诊断、与「吃饭次数」互为因果的可能性大，证据太薄，未收。
- 定 A：正文三项主证据全是随机对照试验（13 项试验的荟萃 + 两项 RCT，其中一项跟踪 12 个月），数字可逐字核对。
- 收益定「小」：这条否掉的是两个无效做法，读者照做拿到的是零，不是降幅；按「只有替代终点记小」的阈值套。成本三项全零，落性价比一般档（收益小拉下来的）。
- 标了「争议」，而且正反两侧都给了原始文献：观察性那一侧（不吃早餐心血管病高 17%、心血管死亡高 49%）和限时进食那一侧（等热量下还能多减 1.46 kg）都和正文结论对立，各写进备注并附 DOI。
- 特别写明 NHANES III 的全因死亡不显著：HR 1.19（0.99–1.42）跨过 1。网上转述这项研究时普遍只引心血管死亡的 1.87，把全因那一项略去，所以备注里把两个数并排写出来。
- 限时进食的两侧怎么调和：荟萃（30 项，多为短期）说有额外好处，最长最严的单项试验（NEJM 12 个月）说没有。备注写成「时间安排影响很小」，不写成「完全无效」。
- 没写的：进食时间与昼夜节律的机制推断（早吃优于晚吃的所谓时辰营养学），人体终点证据不足，未收；也没写任何「轻断食能延寿」的说法，人体没有死亡率终点的随机试验。
- 加了适用范围：糖尿病、正在吃降糖药、怀孕的人漏一顿可能低血糖，备注里写了不适用，按医嘱来。
- 受益人：第①档（你自己）。
