Liver fat response to two days fasting and two days isocaloric high-carbohydrate refeeding in lean and obese women.

Background And Aims: Prolonged fasting, which leads to the mobilization of fat from adipose tissue, can result in the development of hepatosteatosis. However, it is not yet known whether the accumulation of fat in the liver after fasting can be affected by concurrent obesity. Therefore, this study aimed to assess how excessive adiposity influences changes in liver fat content induced by fasting and subsequent refeeding.

Technical note: MR-compatible pedal ergometer with electromechanical pedal resistance and exercise triggering enhanced by visual feedback via video display.

Background: During and after exercise, dynamic P MR parameters are typically measured using an MR-compatible ergometer. Self-built equipment for local condition can be constructed where possible.

Purpose: To develop a pedal resistance ergometer with rocker arm based on a system that combines electric weight displacement, visual self-monitoring, and exercise triggering.
