The Claim

The results of the study are not generalizable to older adults, women, or individuals with insulin resistance because the study sample consisted exclusively of nine healthy young men.

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.

Description
1 study reviewed
In plain English

This study's results apply only to nine healthy young men and cannot be applied to older adults, women, or people with insulin resistance.

See the scientific wording

The findings from this study cannot be generalized to older adults, women, or individuals with insulin resistance, as the trial was limited to nine healthy young men.

Why this might work

Young men's muscles respond to fasting by changing how they use insulin and build protein, but older people, women, and those with insulin resistance have different muscle biology that changes how they react to the same fasting condition.

What the research says

1 study

  1. Study: Effect of an acute prolonged overnight fast on skeletal muscle insulin and anabolic sensitivity in healthy men.

    This study only looked at nine young, healthy men, so we don't know if fasting helps older people, women, or those with insulin problems. The researchers even said we need to study those other groups separately.
