Abstract: A method for reducing cellulite, local or generalized fat comprising applying thermal body wraps, which are cycled in temperature, is provided. Based on a body composition test, suggested targets for body fat percentage, total weight, fat weight, lean weight, weight to lose, body water percentage and basal metabolic rate are calculated. The thermal body wraps are described and may comprise layers of synthetic material, such as polyurethane and polyester fabric. The body wraps may have a heating circuit including a coaxially arranged heating cable, and a control loop including a negative temperature coefficient thermistor. The heating cable may have a protection wire, coaxially surrounding and insulated from a heating wire, so that if a break in the heating wire is detected, current flow to the heating wire is suspended. A thermostat in the wrap provides additional safety.
