The Claim
In adults with insulin resistance, an 8-week low-energy-density diet high in potatoes or beans has no significant effect on fasting serum glucose levels, despite improvements in insulin sensitivity and body weight.
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.
In adults with insulin resistance, eating a low-energy-density diet rich in potatoes or beans for 8 weeks does not change fasting blood glucose levels, even though insulin sensitivity and body weight improve.
See the scientific wording
In adults with insulin resistance, an 8-week low-energy-density diet high in potatoes or beans does not significantly alter fasting serum glucose levels, despite improvements in insulin sensitivity and body weight.
Eating large volumes of potatoes or beans reduces total calorie intake because they fill the stomach without adding many calories. This causes the body to burn stored fat, which improves how well insulin works. At the same time, undigested parts of these foods feed gut bacteria, which produce chemicals that signal the pancreas to release insulin more efficiently. These changes make the body use insulin better, but they do not change the amount of sugar in the blood when fasting because the liver keeps producing the same amount of glucose.
What the research says
1 studyThis study found that when people with insulin resistance ate diets full of potatoes or beans for 8 weeks, they lost weight and their bodies became better at using insulin—but their fasting blood sugar stayed the same. So yes, the claim is right.
