Postprandial Walking is Better for Lowering the Glycemic Effect of Dinner than Pre-Dinner Exercise in Type 2 Diabetic Individuals

Acute Effects of Postprandial Aerobic Exercise on Glucose and Lipoprotein Metabolism in Healthy Young Women

“…It is reported that postabsorptive exercise has the advantage of promoting fat use, whereas postprandial exercise can attenuate the glycemic response to breakfast in sedentary males with metabolic syndrome 25) . Postprandial exercise may be more effective for lowering the glycemic impact of the evening meal in individuals with type 2 diabetes compared with pre-meal exercise 26) . In this study, we showed that postprandial exercise is beneficial for the…”

Post-Meal Exercise may Attenuate the Glycemic Response to a Carbohydrate Load: Important Implications for Adults who are Obese, with Pre-Diabetes or Diabetes, and/or At-Risk for Dementia

“…56 Colberg and colleagues examined the effect of 20 min of moderate walking before or after meal consumption in individuals with T2DM. 57 They found that post-meal exercise resulted in lower plasma glucose levels at the end of exercise compared to values at the same time point when subjects had walked pre-meal. Additional studies found post-meal exercise (1 hour moderate exercise 58 or a short bout of intense exercise) 59 resulted in reduced hyperglycemia in those with T2DM; however, the exercise did not commence immediately after meal consumption.…”

“…50 However, compliance with current exercise recommendations is poor, with self-reported compliance rates of about 35% for those with T2DM. 51 Emerging evidence [52][53][54][55][56][57][58][59] suggests that a short bout of post-meal exercise in particular can attenuate the spike in BG after consumption of carbohydrates, which may be advantageous for those with and without diabetes, including those with dementia. Knowing that a short bout of exercise after consumption of a carbohydrate load could specifically decrease the spike in BG after carbohydrate consumption may be more motivating for compliance than exercising for general improvements in glycemic control.…”

A single bout of exercise and postprandial hyperglycemia caused by high-fat diet

“…Therefore, exercise can be one approach to improve postprandial hyperglycemia. In fact, experimental studies have found that a single bout of exercise during the postprandial period significantly decreases postprandial blood glucose and insulin concentration, compared to no exercise [29][30][31] . Recently, several studies using a continuous glucose monitoring system reported the continuous effects of a single bout of exercise on postprandial glucose response in free-living conditions.…”
