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.

In plain English

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.

Why this might work

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.

  1. Study: 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.
