The Claim
Interrupting prolonged sitting with 28 minutes of total light- or moderate-intensity walking spread over 5 hours reduces postprandial insulin secretion and improves insulin sensitivity in overweight adults aged 45–65, and this reduction in insulin secretion and improvement in insulin sensitivity are associated with preservation of pancreatic β-cell function.
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.
In overweight adults aged 45–65, taking 28 minutes of light or moderate walking spread over five hours after meals lowers insulin levels after eating and increases the body's response to insulin, which is linked to maintained function of insulin-producing cells in the pancreas.
See the scientific wording
Interrupting prolonged sitting with 28 minutes of total light- or moderate-intensity walking spread over 5 hours reduces postprandial insulin secretion and improves insulin sensitivity in overweight adults aged 45–65, suggesting a potential mechanism for preserving pancreatic β-cell function.
When a person walks after sitting for a long time, their leg muscles contract and pull glucose out of the blood without needing insulin. This lowers blood sugar levels, so the pancreas doesn't have to release as much insulin. Less insulin release means the insulin-producing cells in the pancreas aren't overworked, which helps them stay healthy.

1 studyStudy: Breaking Up Prolonged Sitting Reduces Postprandial Glucose and Insulin Responses
When overweight middle-aged adults take short walks every 20 minutes during a long sitting period, their bodies need to produce less insulin after eating, which means their pancreas doesn't have to work as hard.
