A highly detailed, medically accurate 3D anatomical male human model created for educational medical visualization. The model has NO skin layer visible. The body is shown in a neutral anatomical standing position, front view, arms slightly abducted away from the torso. The model represents an overweight body composition. A thick, realistic yellow adipose tissue layer clearly covers the abdomen, chest, flanks, lower back, upper arms, thighs, and gluteal region. The fat layer is smooth, soft, and evenly distributed. It must visibly sit above the muscle layer. The underlying muscles are barely visible due to the thickness of the fat layer. There must be NO visible six-pack abs, NO defined chest separation, NO large biceps, NO exaggerated muscle definition. The physique should look soft and bulky, not muscular. The proportions must remain natural and realistic — not cartoonish and not bodybuilder-like. Background: clean dark grey medical studio environment with soft, balanced lighting. No text, no labels, no numbers, no watermark, no typography anywhere in the image. Ultra-realistic 3D medical render, high resolution, detailed muscle anatomy beneath adipose layer, realistic adipose tissue texture, professional anatomical accuracy.
