The Claim
In obese adults, serum magnesium levels are negatively correlated with HbA1c levels, with a correlation coefficient of r = -0.38 and a p-value of 0.005.
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 obesity, lower levels of magnesium in the blood are associated with higher HbA1c levels, indicating worse long-term blood sugar control.
See the scientific wording
In obese adults, serum magnesium levels are negatively correlated with HbA1c (r = -0.38, p = 0.005), suggesting that lower magnesium is associated with poorer long-term glucose control.
Low magnesium in the blood reduces the ability of insulin receptors to activate properly, which stops cells from taking in sugar. At the same time, low magnesium increases inflammation, which further blocks insulin signaling. Together, these effects cause sugar to stay in the blood longer, raising long-term blood sugar levels.
What the research says
1 studyStudy: Magnesium Deficiency and Its Impact on the Development of Insulin Resistance in Obese Individuals
This study found that obese people with less magnesium in their blood tend to have higher average blood sugar levels, which is exactly what the claim says.
