Wide landscape editorial photograph of a mountain biker mid-ride on a dusty red-orange singletrack trail in the South African Western Cape, golden hour light raking across the scene. The rider is in sharp focus on the right third of the frame, wearing a weathered cycling kit with a race number plate on the handlebars, dust kicking up from the rear tire. Behind them, rolling hills covered in fynbos shrubland and silhouetted protea plants fade into soft, hazy blue mountains. Warm amber sunlight creates long shadows and a soft rim light around the rider and bike.

In the lower left foreground, slightly out of focus, a small minimalist glass vial and a clear water bottle sit on a flat sun-bleached rock, with a few drops of liquid catching the light. Next to them, a simple matte paper notecard and a pencil suggest data collection, with no legible text. The vial and bottle are clean, understated, and modern, with no branding.

The color palette is earthy and refined: terracotta, ochre, sage green, dusty teal sky, and cream highlights. The composition uses shallow depth of field, a generous negative space in the upper left sky for headline overlay, and subtle film grain. The mood is contemplative, skeptical, and quietly sophisticated, like a feature photograph from a high-end outdoor sports and science magazine. Natural, candid, cinematic, shot on a 50mm lens with soft contrast and muted saturation. No futuristic elements, no glowing effects, no molecular graphics, no text.

Ketone IQ podniosło poziom ketonów w Cape Epic, ale nie zrobiło nic więcej

BY DR. GYMBRO · 27 paź 2026

Rowerzyści startujący w ośmiodniowym Cape Epic spożywali Ketone IQ dwa razy dziennie, co podniosło ich poziom ketonów do ok. 1 mM, ale ich zmęczenie, tętno, czas reakcji i regeneracja nie różniły się od grupy placebo. Badanie podwójnie zaślepione przeprowadzono w warunkach rzeczywistego wyścigu i wykazało, że umiarkowana ketoza nie przyniosła oczekiwanych efektów, a R‑1,3‑butanodiol nie należy mylić z esterami ketonowymi.
