The Claim

In obese diabetic ob/ob mice, daily subcutaneous injection of GIP(3-42) at 25 nmol/kg for 14 days was associated with modest but statistically significant reductions in non-fasting plasma glucose, improved glucose tolerance during an intraperitoneal glucose challenge, and enhanced insulin sensitivity, without altering insulin secretion, body weight, food intake, or pancreatic islet morphology.

Source: Effects of sub-chronic exposure to naturally occurring N-terminally truncated metabolites of glucose-dependent insulinotrophic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), GIP(3-42) and GLP-1(9-36)amide, on insulin secretion and glucose homeostasis in ob/ob mice.

In plain English

In obese diabetic mice, daily injections of GIP(3-42) for 14 days lowered blood glucose levels, improved how the body responds to glucose, and increased insulin sensitivity, without changing insulin production, body weight, food intake, or pancreatic islet structure.

See the scientific wording

In obese diabetic ob/ob mice, daily subcutaneous injection of GIP(3-42) at 25 nmol/kg for 14 days was associated with modest but statistically significant reductions in non-fasting plasma glucose, improved glucose tolerance during an intraperitoneal glucose challenge, and enhanced insulin sensitivity, without altering insulin secretion, body weight, food intake, or pancreatic islet morphology.

Why this might work

A broken-down version of a gut hormone binds to receptors in muscle, liver, or fat tissue, causing these tissues to take up more glucose from the blood and use it more efficiently, which lowers blood sugar without changing how much insulin the body makes.

  1. Study: Effects of sub-chronic exposure to naturally occurring N-terminally truncated metabolites of glucose-dependent insulinotrophic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), GIP(3-42) and GLP-1(9-36)amide, on insulin secretion and glucose homeostasis in ob/ob mice.

    In diabetic mice, daily shots of a broken-down part of a gut hormone slightly lowered blood sugar and helped the body use insulin better—without changing weight, eating, or insulin production. This matches exactly what the claim says.
