Spot-reduction

Spot reduction of fat from specific body areas — including arms — is not supported by evidence. Fat loss is systemic, determined by genetics and total calorie deficit. Upper body resistance training does build arm muscle, improving appearance. This article explains the physiology.

Facial fat loss cannot be targeted independently from overall fat loss — spot reduction is physiologically impossible. This article explains why, covers the factors affecting facial appearance (fat, fluid retention, and muscle tone), and outlines what evidence-based weight loss produces in terms of facial changes.

Spot reduction — losing fat from a specific body region through targeted exercise — is not physiologically possible. Thigh fat distribution is determined by genetics and hormonal factors, primarily oestrogen. This article reviews the evidence and explains what actually reduces lower body fat.

Spot reduction — targeting fat loss at a specific body location — is not physiologically possible. Kostek et al. (2007) demonstrated no preferential fat loss from exercised limbs. Facial fat changes with overall body fat loss; water retention, sodium, sleep, and alcohol affect daily facial appearance. This article covers what the evidence shows about how face shape changes during weight loss.

Spot reduction of arm fat is not physiologically possible — Kostek et al. (2007) found no preferential fat loss in trained limbs. Arm fat reduces with overall body fat loss through a calorie deficit. Resistance training exercises for the arms (triceps, biceps, deltoids) build lean mass beneath the skin, improving arm appearance and contributing to lean mass preservation during weight loss. This article covers effective arm exercises with calorie and muscle-building context.
