Approach: conceptual metaphor. Palette: D, bold color field.

Subject: a single old-fashioned mechanical light switch, photographed straight on, with its toggle stuck halfway between on and off. It is mounted on a saturated mustard-yellow painted wall. A thin electric green (#00e676) glow leaks from the gap behind the toggle and casts a small green rim onto the plate. Beside it, a row of six small matte black tally marks is scratched into the paint, with the third and fifth marks fainter and partly worn, hinting at inconsistent results across days.

Camera: slightly low, eye-level angle with a 50mm lens, shallow depth of field, and the switch placed on the right third of the frame.

Lighting: hard directional side light from the left casts crisp, warm-neutral shadows with no blue cast. The wall texture and brushstrokes are visible.

Mood: curious, skeptical, and measured. The scene suggests a mechanism that is partly engaged.

模拟禁食饮食推动了人体自噬——但并非每次都有效

模拟禁食饮食（FMD）真的能在人体内启动自噬吗？还是仅在小鼠实验中有效？一项针对 30 名健康成年人的随机对照试验将 ProLon 与另一种 FMD 配方进行比较。干预约六天后，实验组在自噬通量、体重、血糖、酮体和胰岛素抵抗等指标上出现变化，但这些差异并未在所有时间点达到显著，且研究规模小、由 ProLon 制造商赞助。以下是该试验的设计、结果以及适合的人群。
