On the left, a rustic ceramic bowl in matte oatmeal glaze holds ground cinnamon in a soft mound. Beside it sit several whole cinnamon sticks tied with natural twine, and a small wooden spoon dusted with warm reddish-brown powder. A loose cinnamon swirl spills across the surface in a graceful, organic arc. On the right, a minimalist fitness scene flows into the frame: a matte sage-green yoga mat partly unrolled, a stainless steel interval timer reading 00:20, a pair of clean white training sneakers, and a compact black kettlebell. A folded linen towel and a glass bottle of water add quiet, lifestyle-oriented detail. The two halves are linked by a thin line of scattered cinnamon powder that runs across the table like a brushstroke, joining the kitchen and the workout.

Soft morning window light enters from the upper left. It casts gentle, long diffused shadows and highlights the texture of the spice, the grain of the wood, and the curled bark of the sticks. The palette is warm and earthy: cinnamon brown, terracotta, cream, sage green, and soft charcoal, with one small accent of burnt orange. The background is a softly blurred neutral wall with a hint of a leafy plant in the top corner, giving shallow depth of field. The composition leaves generous negative space at the top and center-right for headline text. The mood is calm, fresh, health-forward, and trustworthy, with a subtle scientific-journal sophistication. Crisp focus on the cinnamon, creamy bokeh in the background, and a fine film-like grain. The image is realistic, tactile, and uncluttered, with no people, no text, no logos, and nothing futuristic.

肉桂+Tabata 高强度间歇训练的8周减脂试验

Dr. Gymbro · · 1 min read

如果你的减脂关键已经在调味架上,会怎样?

2025 年,*《国际运动营养学会杂志》(Journal of the International Society of Sports Nutrition)*发表了一项小规模试验,恰好验证了这一设想。将 Tabata 风格的高强度间歇训练(HIIT)与每日 1.5 克肉桂相结合的男性,其体脂下降幅度显著高于仅做 Tabata 的对照组。想大量囤积肉桂前,先了解实验细节与局限性吧。

试验设计

伊朗研究团队招募了 40 名超重或肥胖的男性士兵,随机分为四组(每组约 10 人):

  • 仅 Tabata(T)
  • Tabata + 肉桂(T+S)
  • 仅肉桂(S)
  • 对照(C)

干预为期八周,每周三次训练。肉桂组每日服用三粒 500 mg 胶囊,合计 1.5 g(约半茶匙)。研究人员测量了体成分、力量耐力表现(俯卧撑、深蹲、平板支撑、垂直跳)、空腹血糖、胰岛素、肝酶以及多项炎症标志物。

Tabata 训练方案

采用经典 Tabata 节奏:20 秒全力工作,10 秒休息,共 8 轮循环(总时长约 4 分钟)。循环包括以下八个动作:

  1. 跳深蹲
  2. 背部伸展
  3. 仰卧起坐
  4. 俯卧撑
  5. 三头肌屈伸
  6. 侧腹卷腹
  7. 药球军用推举
  8. 引体向上

原文摘要未具体说明每个动作的轮次数,故可将上述“4 分钟模式”视为本研究的基本方案,而非经过严格验证的完整时长。

结果(关键数据)

  • 体重、BMI 与体脂率:所有干预组均显著下降(p < 0.001),对照组基本持平。
  • 体脂下降幅度:组合组(Tabata+肉桂)最大,下降 7.86%,显著优于单纯 Tabata 组(p = 0.013)。
  • 体能表现:俯卧撑、深蹲、平板支撑和垂直跳均在两组训练中提升,Tabata 与 Tabata+肉桂之间差异不大,说明肉桂本身并未直接提升力量或耐力。
  • 代谢指标:空腹血糖、胰岛素、HOMA‑IR 以及肝酶(SGOT、SGPT、GGT)在所有干预组均有下降,组合组幅度最大。
  • 炎症与肌因子:CRP、TNF‑α 降低,脂联素、irisin 升高,组合组的变化显著优于其他组(p < 0.05)。

二次数据整理显示,单纯 Tabata 组平均体重下降约 7 kg,组合组约 6 kg。这暗示组合组可能在保持或略增肌肉量的同时更快减少脂肪——这一点仍需完整论文的进一步验证。

肉桂可能发挥作用的机制

作者倾向于将关注点放在炎症与肌因子信号上,而非直接的脂肪燃烧。慢性低度炎症(如 TNF‑α 升高)与胰岛素抵抗和顽固性肥胖密切相关。肉桂中的多酚被认为能够抑制炎症通路。irisin 是肌肉释放的类激素,能促进脂肪组织的棕色化和能量消耗。两者在组合组的改变最为显著。

虽然肉桂常被宣传为“提升胰岛素敏感性”,但本研究中血糖、胰岛素及 HOMA‑IR 在所有干预组(包括仅训练组)都有所改善,表明运动是代谢改善的主要驱动,肉桂的额外益处更可能体现在炎症调节上。这仅是机制层面的推测,研究并未专门设定检验该路径的实验设计。

单独使用肉桂并非魔法燃脂药

摘要将肉桂描述为 “增强”(potentiated) Tabata 效果的因素,而不是替代品。对照组几乎没有变化,训练组提升体能,单独肉桂组也未能匹配组合组的表现。换句话说,“训练加肉桂可能优于仅训练”,而非“肉桂可以直接燃掉脂肪”。

研究的局限性

  • 样本极小:每组约十人,统计力度不足,结论不够坚实。
  • 受试者单一:仅为年轻男性士兵,难以直接推广至普通人群。
  • 盲法不明:若参与者知道自己是否服用肉桂,期待效应可能介入。
  • 肉桂种类未标明:不同提取方式和来源对结果复现至关重要。
  • 单国单次试验:需要独立的重复研究予以验证。

实用建议

剂量

本试验使用的剂量为 每日 1.5 g(每次 500 mg,三次)。目前仅有该剂量得到实验支持,未显示需进一步提高。

锡兰肉桂 vs. 肉桂(Cassia)

市面上大多数肉桂为 Cassia(俗称肉桂),其中含有一定量的香豆素(coumarin),高剂量摄入可能增加肝脏负担。欧盟等监管机构将安全摄入上限设为 体重每公斤约 0.1 mg 香豆素。不同产品的香豆素含量差异很大,若计划长期每日服用,建议选用 锡兰肉桂(Ceylon)——香豆素含量极低,更为安全,尤其适合有肝脏问题的朋友。

适用人群

已经坚持结构化高强度间歇训练、希望以低成本方式略微提升效果的健康成年人。绝不是逃避训练的捷径。

需要先咨询的情况

服用糖尿病药物、抗凝血药或已有肝病者,请在补充前先与医生沟通。初学者也应先打好基础,再尝试全力 Tabata。

结论

真正的亮点在于训练本身:八周 Tabata 循环即可改善体成分、体能、炎症以及肝功能指标。肉桂看起来是一个廉价且合理的增效剂,使本小规模试验中的脂肪下降更为显著。它值得关注,但尚未得到充分验证,仍需更多大样本、双盲、跨人群的研究来确认其效果。

磷虾油在隔日禁食中将肌肉流失降低至原来的六分之一

BY DR. GYMBRO ·

严格的减肥往往意味着脂肪和肌肉一起流失,但最新的随机对照试验显示,某种补剂或许能改变这一局面。41 名进行 8 周隔日禁食的成年人中,磷虾油组和安慰剂组的体重下降相近(约 4.6 与 4.5 公斤),而磷虾油组仅损失 0.2 公斤的无脂体重,安慰剂组则损失 1.2 公斤,同时握力也得以保持。需注意样本量有限,胶囊中还含有虾青素和胆碱。下面给出具体数据、剂量以及不适合人群的提示。

A wide, editorial-style flat lay photographed from above on a pale, warm-toned marble surface with soft natural window light coming from the left. At the center sits a shallow ceramic bowl filled with glistening golden-amber fish oil capsules, a few spilled casually onto the marble. Beside the bowl, a sleek minimalist bathroom scale in matte white sits at the right edge, its digital display blurred so it appears static. To the left, a neatly folded heather-gray athletic towel rests beside a small cluster of fresh ingredients: a halved lemon, a sprig of dill, and a fillet of raw salmon on a slate board, its coral-pink flesh with delicate white marbling catching the light. Near the top of the frame, a pair of brushed-steel dumbbells in a light finish and a soft tape measure curl loosely across the surface, suggesting body composition tracking without being clinical. A small glass of water with condensation and a linen napkin add quiet lifestyle detail. The color palette is calm and modern: cream, soft sage green, warm gold, coral, and muted gray. Shadows are soft and diffused, with gentle highlights on the capsules making them glow like tiny amber beads. The composition has generous negative space on the upper left for headline text, with a shallow depth of field that keeps the capsules and salmon crisp while the edges fall softly out of focus. The overall mood is clean, health-conscious, and contemporary, like a high-end wellness magazine or science journal cover, with a subtle film-like grain and natural, true-to-life tones.

鱼油 6 周后让脂肪转为肌肉,体重却不变

BY DR. GYMBRO ·

体重秤的数字没动,但体内的脂肪悄悄换成了肌肉会怎样?一项针对 44 名健康成年人的双盲试验发现,连续 6 周每天摄入约 2.4 克 EPA+DHA 的鱼油后,瘦体重增加约 0.5 kg、脂肪减少约 0.5 kg,体重保持不变。唾液皮质醇水平下降与这些变化有关,但仅为相关性。静息代谢率未见显著变化,且样本量较小。下面我们一起拆解数据,看看它到底能说明什么,以及该如何理性使用这些信息。

A wide, editorial-style photograph of a lone cyclist's legs and torso mid-sprint on a stationary indoor bike in a bright, minimalist performance studio. The scene is shot from a low three-quarter angle with shallow depth of field. The cyclist wears matte charcoal shorts and a fitted sage-green top, with a subtle sheen of sweat catching soft window light. Their hands grip the handlebars and the pedals are caught in a slight motion blur, which conveys explosive effort.

In the foreground, slightly out of focus on a pale oak side table, sit a small matte white scoop and a clear glass of water. Next to them is a little ceramic dish holding a few off-white capsules and a pinch of fine white powder. A folded linen towel and a slim stopwatch rest nearby. The stopwatch face is softly legible, hinting at timed sprint intervals.

The background is warm cream concrete and pale wood, with tall windows casting long diagonal shafts of golden morning light across the floor. Faint dust motes drift in the light. On the wall behind, a clean, abstract line graph is painted in muted terracotta and deep teal. It shows one line rising in steps like five sprint bouts and another line gently falling, a subtle visual nod to power up and lactate down. The graph is minimal and stylized, with no readable numbers or text.

The color palette is earthy and modern: sage green, terracotta, warm cream, soft charcoal, and touches of natural wood. The lighting is soft and directional with gentle highlights and natural shadows. The overall look is calm, refined, and contemporary, like a premium wellness and sports science magazine cover. The composition follows the rule of thirds, with the cyclist on the right and open negative space on the left for a headline. The image is crisp, grainy in a subtle film-like way, and free of any futuristic or sci-fi elements.

这款肉碱可将冲刺功率提升最高15%,并降低乳酸

BY DR. GYMBRO ·

2009 年的一项交叉研究发现,单次口服 4.5 克甘氨酸丙酰‑L‑肉碱(GPLC)可使五次全力自行车冲刺的峰值和平均功率提升 2.6%‑15%。运动后 14 分钟血乳酸浓度下降 16.2%。但该“15%”仅为最高值,非平均提升,且研究仅在 24 位男性受试者、单一实验室中完成。本文将对 GPLC 与普通 L‑肉碱、ALCAR 的区别、硝酸盐假说的来源、可能受益的人群以及剂量、使用时机和证据局限性进行详细解析。

A wide, softly lit editorial still life on a pale oatmeal linen surface. In the center sits a tall, clear glass filled with deep garnet-red tart cherry juice, with condensation beading on the outside and a faint ruby glow where light passes through it. Around it are a scattering of fresh Montmorency cherries, some with stems and some halved to show pale amber flesh and a single pit. A few drops of juice have splashed onto the linen, leaving small crimson stains. To the right, slightly out of focus, lies a folded charcoal-gray running shirt, a pair of minimalist off-white running shoes, and a small brushed-steel kettlebell, suggesting both endurance and strength training without a gym in view. On the left, a ceramic pitcher in matte sage green holds more juice, and a sprig of fresh mint adds a small contrast.

Window light comes from the upper left, casting long, gentle shadows and creating a warm morning feel. The palette is restrained and modern: deep burgundy, cream, sage, and soft slate, with plenty of negative space in the upper right for headline text. The camera angle is a shallow three-quarter view from slightly above, with a shallow depth of field. The foreground cherries are razor sharp and the background melts into a creamy blur. Subtle film grain, natural color grading, and a clean, minimalist composition give it the polished feel of a contemporary health and science magazine. No text, no logos, no people, and no futuristic elements. The overall mood is calm, fresh, and restorative, hinting at recovery and balance.
