Intermittent fasting does not significantly affect Glycosylated Hemoglobin (HbA1c), Low-Density Lipoprotein Cholesterol (LDL-C), or High-Density Lipoprotein Cholesterol (HDL-C) compared to control diets.
If your primary goal is to lower LDL cholesterol or improve HbA1c, intermittent fasting alone may not be sufficient. While it helps with weight, blood pressure, and triglycerides, it does not significantly change LDL, HDL, or long-term blood sugar markers (HbA1c). You may need to combine IF with other dietary strategies or medications to address these specific markers.
No effects were observed for low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, or glycosylated hemoglobin.
