The Claim
Prolonged uninterrupted sitting for 5 hours after a high-carbohydrate, high-fat meal results in a postprandial glucose area under the curve of approximately 6.9 mmol/L·h and an insulin area under the curve of 828.6 pmol/L·h in overweight adults aged 45–65.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After eating a high-carb, high-fat meal, sitting still for five hours leads to a glucose response of about 6.9 mmol/L·h and an insulin response of about 828.6 pmol/L·h in overweight adults aged 45–65.
See the scientific wording
Prolonged uninterrupted sitting for 5 hours after a high-carbohydrate, high-fat meal leads to a postprandial glucose area under the curve of approximately 6.9 mmol/L·h and insulin area under the curve of 828.6 pmol/L·h in overweight adults aged 45–65, establishing a baseline for metabolic dysregulation during sedentary behavior.
When a person sits still for hours after eating a fatty, sugary meal, the muscles don't contract, so they don't pull glucose out of the blood. The pancreas responds by pumping out more insulin to force glucose into cells. This causes blood sugar and insulin levels to stay high for a long time, creating metabolic stress.
What the research says
1 studyStudy: Breaking Up Prolonged Sitting Reduces Postprandial Glucose and Insulin Responses
This study found that sitting still for 5 hours after a fatty meal causes big spikes in blood sugar and insulin, just like the claim says—and taking short walks every 20 minutes helps bring those levels down.
