The Claim

Liver glucose uptake during insulin stimulation is not strongly correlated with whole-body insulin sensitivity or skeletal muscle glucose uptake, and its association with insulin resistance is inconsistent, indicating that liver insulin resistance is regulated independently of muscle and adipose tissue.

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

The liver's uptake of glucose in response to insulin does not strongly relate to how sensitive the whole body is to insulin or how much glucose skeletal muscle takes up, and its connection to insulin resistance varies across studies, suggesting the liver's response to insulin is controlled separately from muscle and fat tissue.

See the scientific wording

Liver glucose uptake during insulin stimulation is not strongly correlated with whole-body insulin sensitivity or skeletal muscle glucose uptake, and its association with insulin resistance is inconsistent, suggesting liver insulin resistance is regulated independently of muscle and adipose tissue.

Why this might work

In the liver, insulin suppresses glucose production and promotes storage, but does not rely on the same transporter used by muscle and fat to take in sugar. Muscle and fat use a specific protein to pull sugar into cells when insulin is present, but the liver uses a different system that controls how much sugar it releases instead. This means the liver can become resistant to insulin without affecting how muscle and fat respond, and vice versa.

1 study

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

    The study found that how well the liver takes up sugar when insulin is present doesn’t match up well with how well muscles or fat do — meaning the liver works differently than other tissues when it comes to insulin.
