PPG spikes can be prevented by replacing high with low glycemic load foods and dampened by engaging in postprandial physical activity. This is exemplified by the integrated Glycemic load, Exercise and Monitoring glucose (GEM) program. It promotes choices of low glycemic load foods and increased physical activity, directed by glucose monitoring feedback. Glucose feedback can: 1) educate people as to what food choices minimize PPG and what physical activity choices directly lower PPG, 2) activate individuals when glucose is out of their desired range by alerting them to make choices to lower high glucose or raise low glucose, and 3) motivate individuals to repeat those choices that resulted in desirable glucose consequences. The educating, activating and motivating benefits of glucose feedback are thought to be qualitatively and quantitatively enhanced through continuous glucose monitoring (CGM).
