Understanding Metabolic Health: Why It Matters More Than You Think
Just read the latest NYT piece on metabolic health and wanted to share the key takeaways. What we are actually dealing with: An estimated 90 percent of American adults have some degree of metabolic dysfunction. Risk increases when someone has three or more of the following: - High waist circumference, especially abdominal fat - High triglycerides - Low HDL cholesterol - High blood pressure - High blood sugar Why excess body fat plays such a big role: When calorie intake consistently exceeds what the body can use, fat cells become overloaded. Triglycerides begin accumulating in places they do not belong, such as the liver and muscle tissue. These fat cells also release inflammatory signals that interfere with insulin function, which then feeds back into weight gain and metabolic dysfunction. It becomes a self reinforcing cycle. Why body fat distribution matters: Not all fat behaves the same. Subcutaneous fat under the skin and visceral fat around the organs are biologically different. People who store more fat in the abdomen tend to experience more metabolic issues than those who store fat in the hips and thighs. This comes down to differences in gene expression and inflammatory signaling. How metabolic dysfunction develops: It rarely appears all at once. One person may start with rising blood pressure, another with cholesterol changes, another with elevated blood sugar. Over time, these issues compound. One of the most important warning signs is not a single lab value, but numbers that steadily trend in the wrong direction between doctor visits. What it leads to over time: If left unaddressed, metabolic dysfunction places ongoing stress on nearly every system in the body. High blood pressure damages arteries and increases plaque buildup, raising the risk of heart attack and stroke. Diabetes damages blood vessels and kidney filtration units. Fat accumulation in the liver can progress to MASLD, including inflammation and irreversible scarring. At least thirteen types of cancer are more common in people who are overweight or obese, and elevated insulin levels can accelerate tumor growth.
