The Claim

Aging is associated with increased glucose uptake in the liver and adipose tissue, but not in skeletal muscle, indicating a shift in insulin-stimulated glucose disposal from skeletal muscle to liver and adipose tissue with age.

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.

How it works
1 study reviewed
In plain English

With age, the liver and fat tissue take up more glucose in response to insulin, while skeletal muscle does not, resulting in a change in where the body directs glucose after eating.

See the scientific wording

Aging is associated with increased glucose uptake in liver and adipose tissue, but not in skeletal muscle, suggesting that insulin-stimulated glucose disposal shifts from muscle to fat and liver with age, potentially contributing to metabolic inflexibility.

Why this might work

As people age, muscle cells become less responsive to insulin, so they take up less glucose. The liver and fat cells keep responding to insulin, so they take up more glucose. High levels of fat in the blood from fat tissue prevent muscle cells from using insulin properly, forcing the body to rely more on liver and fat to handle glucose.

  1. Study: Insulin-stimulated glucose uptake in skeletal muscle, adipose tissue and liver: a positron emission tomography study

    Principal component analysis showed age positively loaded on components associated with liver and subcutaneous adipose tissue glucose uptake, but not muscle uptake, indicating an age-related shift in tissue-specific glucose disposal patterns.
