For women, a low HDL level that indicates metabolic syndrome is defined as:

A low HDL (high-density lipoprotein) level is an important factor in determining metabolic syndrome, particularly for women. In the context of metabolic syndrome, a low HDL level signifies an increased risk for cardiovascular issues and other metabolic disorders.

For women specifically, the threshold defining a low HDL level is set at less than 50 mg/dl. This level is significant because HDL is often referred to as "good" cholesterol due to its role in removing other forms of cholesterol from the bloodstream. When the HDL level falls below this threshold, it can indicate a higher risk of developing health problems, including heart disease.

Understanding the implications of HDL levels is crucial for health and wellness coaches, as they need to be able to identify risk factors associated with metabolic syndrome to help clients adopt healthier lifestyle choices. The value of less than 50 mg/dl for women underscores the importance of maintaining a healthy level of HDL as part of an overall strategy for reducing health risks.
