The whole corona virus lockdown has certainly taught me many different things such as not taking freedom for granted, slowing down from the rat race of life, enjoying the little things like sunlight and fresh air. Above all, it has reminded me the importance of metabolic health.

Metabolic Illness is a Predictor of Severe Coronavirus Illness

Reports from China, France, Italy and most recently from the NY Times all confirm: “Obesity may be one of the most important predictors of severe coronavirus illness, new studies say. It’s an alarming finding for the United States, which has one of the highest obesity rates in the world.” (1)

This is not a unique finding to Sars-Cov-2 believe it or not. When MERS-Covid attacked the world in 2012, “Epidemiological studies identified diabetes as the primary comorbidity associated with severe or lethal MERS-CoV infection.” (2)

Why is this so important in the United States? A study published in 2019 (3) surveyed 8721 Americans from 2009-2016 and found that more than 80% of that group was metabolically unhealthy.

Using the most recent guidelines, metabolic health was defined as having:
optimal levels of waist circumference (WC <40” / 34” for men/women),
glucose (fasting glucose <100 mg/dL and hemoglobin A1c <5.7%),
blood pressure (systolic <120 and diastolic <80 mmHg),
triglycerides (<150 mg/dL), and high-density lipoprotein cholesterol (≥40/50 mg/dL for men/women), and not taking any related medication.

Americans are at Risk

According to the CDC in 2018 over 42% of Americans were obese (4). Based on data from 2016, 30% of people are over weight, not yet obese (5). That means that right now, 71.6% of America is overweight or obese! By 2030 it is expected that more that 50% will be considered obese.

A key marker in metabolic disease is hyperinsulinemia in which the body requires excess insulin to control the amount of blood that is in the bloodstream. In 1975 Dr. Joseph R. Kraft published a study that showed high insulin levels can precede a diagnosis of Diabetes by up to 15 years or more.(6) Another mini-review showed that high insulin levels was an early indicator of Metabolic Dysfunction. (7)(8)

You Can Decrease Your Risk

Why is this important? The best “cure” to the Covid-19 infection is to prevent the sequelae of the infection. One of the easiest ways is to fix the diet. We have seen people no longer need insulin, diabetes medications, hypertensive medications, cholesterol medications within weeks to months by simply changing what they are eating.

This is your chance. While we’re home, you can have a positive impact on your immune system so it’s more able to fight any virus or bacteria. This disease effects people with metabolic syndrome and obesity at disproportionate levels.

Make the changes now, not just for this pandemic, but for the rest of your life.
