The Claim

In obese mice, calorie restriction reduces hepatic diacylglycerol and protein kinase C epsilon activity, which is associated with restored insulin-stimulated Akt phosphorylation and improved liver insulin sensitivity, independent of total ceramide levels.

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

In obese mice, reducing calorie intake lowers specific fat molecules and enzyme activity in the liver, which is linked to improved insulin signaling in the liver without changing ceramide levels.

See the scientific wording

In obese mice, calorie restriction rapidly reduces hepatic diacylglycerol and protein kinase C epsilon activity, which correlates with restored insulin-stimulated Akt phosphorylation and improved liver insulin sensitivity, independent of changes in total ceramide levels.

Why this might work

When food intake drops, the liver stops making excess fat and starts burning more fat for energy. This lowers a specific fat molecule called diacylglycerol, which stops a blocking enzyme called PKCε from interfering with insulin's signal. Without this block, insulin can activate Akt, allowing the liver to take up and use glucose properly.

What the research says

  1. Study: Integrated analysis of insulin resistance reveals metabolic remodeling following diet switch–triggered calorie reduction

    When obese mice eat less food, their liver fat and a troublesome enzyme (PKCε) drop quickly, helping the liver respond better to insulin—even though other fat molecules (ceramides) stay the same.
