High dietary calcium intake increases thermogenesis and uncoupling protein-2 (UCP-2) expression, contributing to energy expenditure and weight loss independent of caloric restriction.

This mechanism is more relevant to understanding the biological basis of calcium's effect rather than a direct actionable step for humans, as the temperature increase is modest and observed in animal models.

GoodSupportsHIGH confidence
high calcium diets caused marked reductions in fatty acid synthase expression and activity (35% to 81%), two- to threefold increases in lipolysis and increases in core temperature (0.48 – 0.67°C) and uncoupling protein-2 (UCP-2) expression during energy restriction

Why this rating

Supported by animal studies showing increased core temperature and UCP-2 expression.
