The Claim
A high-fat diet consumed over several weeks is associated with reduced insulin sensitivity in healthy women of African-American and Caucasian races.
What the research says
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.
Women who eat a high-fat diet for several weeks show lower insulin sensitivity compared to those who do not.
See the scientific wording
A high-fat diet consumed over several weeks is associated with reduced insulin sensitivity in healthy women of both African-American and Caucasian races, suggesting dietary fat content may influence metabolic regulation.
When a person eats a lot of fat over time, fat molecules build up inside muscle and liver cells. This buildup interferes with the signals that tell the cells to take in sugar from the blood. As a result, the cells stop responding properly to insulin, and sugar stays in the blood longer than it should.
What the research says
1 studyThis study found that when healthy women ate a lot of fat for several weeks, their bodies became less able to use insulin properly to manage sugar — no matter if they were African-American or Caucasian. So yes, eating too much fat can make it harder for the body to control blood sugar.
