A softly lit editorial still life on a pale oatmeal-colored linen surface, shot from a slightly elevated three-quarter angle with a shallow depth of field. In the left foreground, a small ceramic dish holds several translucent golden-amber fish oil softgel capsules, glowing as if lit from within by warm morning window light. A few capsules are scattered casually beside it, catching crisp highlights. Just behind them, a sliced fresh salmon fillet with vivid coral-orange flesh rests on a matte slate board next to a sprig of dill, a halved lemon, and a small glass dropper bottle of golden oil.

In the soft-focus midground, a pair of weathered, capable older adult hands rests on the edge of the table, gently holding a pale sage-green resistance band, a hint of an active lifestyle. Beside them sits a modest set of brushed-steel dumbbells and a folded heather-gray towel. Subtle natural details add warmth: a glass of water, a small ceramic mug, and a sprig of eucalyptus in a bud vase.

On the right side, a tidy stack of printed research papers with a few pastel sticky tabs and a pair of thin tortoiseshell reading glasses sits on top, suggesting scholarly review. A fountain pen lies across the pages, with a few abstract handwritten notes and a simple hand-drawn bar chart visible but unreadable.

The palette is warm and calming: cream, soft sage, terracotta, honey gold, and coral accents against muted neutral tones. Window light enters from the left, producing long gentle shadows and a faint dappled leaf-shadow pattern across the linen. The background fades into a creamy blur of pale wall and a hint of a wooden shelf.

The composition leaves clean negative space across the upper right third for headline text overlay. The mood is trustworthy, health-forward, and modern, reminiscent of a contemporary wellness and science journal's photography.

加齢に伴う筋肉衰えに対する魚油の効果：14件の研究が示す実際のところ

BY DR. GYMBRO · 2026年10月25日

魚油は加齢による筋肉の衰えを防ぐ“防具”として宣伝されていますが、実際のエビデンスはどうでしょうか。2026 年のアンブレラレビューでは、55 歳以上の成人を対象としたランダム化比較試験 7 件とメタアナリシス 7 件を総合しています。その結果、下肢の筋力と身体機能においてわずかながら測定可能な改善が見られましたが、握力や歩行速度、上肢筋力については不確実性が高いと指摘されています。重複した研究が多く含まれるため、エビデンスは見かけほど堅牢ではありません。

A bright, minimalist editorial still life on a soft warm-white linen surface, shot from a slightly elevated angle in natural morning window light. In the center, a small shallow ceramic bowl in matte oatmeal tones holds several glossy, translucent coral-red softgel capsules, with a few spilled onto the surface in a gentle arc. Beside the bowl, a single ripe peach-pink shrimp-like krill shape is absent; instead a delicate scatter of tiny coral-orange dried krill-pink petals and a sprig of pale green seaweed hint at the marine origin. To the left, an empty clear glass of water and a folded cream napkin suggest fasting. To the right, a simple matte white plate sits bare with a silver fork resting across it. In the soft-focus background, a pair of sage green hand weights and a neatly rolled yoga mat in dusty blue add a quiet nod to muscle and strength. Soft shadows fall diagonally across the scene, giving gentle depth. The palette is calm and modern: warm ivory, coral red, sage green, dusty blue, and soft beige. Shallow depth of field with crisp focus on the capsules, which catch small bright highlights. Clean negative space on the left third of the frame for headline text. The overall feel is a contemporary wellness magazine or health journal cover, airy, refined, and editorial, with subtle film-like grain and natural color grading. Landscape 16:9 composition.

クリルオイル、断食ダイエットで筋肉減少を最大6倍抑制（試験）

BY DR. GYMBRO · 2026年10月24日

ハードなダイエットは脂肪だけでなく筋肉も失いやすいが、最新のランダム化比較試験でサプリメントがその傾向を変える可能性が示された。8週間の隔日断食（ADF）を行った41名の成人で、クリルオイル群とプラセボ群は体重減少がほぼ同じ（約4.6kg対4.5kg）だった。ところがクリルオイル群は除脂肪体量がわずか0.2kg減少したのに対し、プラセボ群は1.2kgと大きく減少し、握力も維持できた。ただしサンプル数が少なく、カプセルにはアスタキサンチンとコリンも含まれている点に注意が必要だ。

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. No people, no text, no futuristic elements.

魚油摂取6週間で脂肪が筋肉に置き換わったが、体重は変わらなかった

BY DR. GYMBRO · 2026年10月23日

体重計の数値は変わらなくても、体は密かに脂肪を筋肉へと置き換えているかもしれません。44名の健康な成人を対象にした二重盲検試験で、1日約2.4 gのEPA＋DHAを含む魚油を6週間摂取すると、体組成が約0.5 kg変化し、体重は変わりませんでした。唾液中コルチゾールの低下がこの変化と相関していましたが、因果関係は示されていません。安静時代謝率は変化せず、サンプル数も少ない点に注意が必要です。以下では実データと賢い活用法を解説します。
