The Claim

In rats with diet-induced insulin resistance, lupin protein isolate increases liver Gsk3b gene expression, which reduces inhibition of glycogen synthase activity and improves insulin signaling.

Source: Lupin protein isolate improves insulin sensitivity and steatohepatitis in vivo and modulates the expression of the Fasn, Gys2, and Gsk3b genes

How it works
1 study reviewed
In plain English

In rats with insulin resistance caused by diet, lupin protein isolate increases Gsk3b gene activity in the liver, leading to reduced suppression of glycogen synthase and enhanced insulin signaling.

See the scientific wording

In rats with diet-induced insulin resistance, lupin protein isolate increases liver Gsk3b gene expression, which may contribute to improved insulin signaling by reducing inhibition of glycogen synthase activity.

Why this might work

Lupin protein isolate reaches the liver and turns on genes that make more glycogen synthase and adjust a regulatory enzyme, allowing the liver to store more sugar as glycogen. This lowers blood sugar and improves how the body responds to insulin.

  1. Study: Lupin protein isolate improves insulin sensitivity and steatohepatitis in vivo and modulates the expression of the Fasn, Gys2, and Gsk3b genes

    In rats with insulin problems, feeding them lupin protein made a key liver gene (Gsk3b) more active, which helped their bodies use insulin better and store sugar more efficiently. This matches what the claim says.
