It may be that Eat less; move more; live longer which I have been writing about for nearly 10 years here, also has some relevance in the fight against COVID-19 .
In a Nature Reviews Endocrinology “Comment” authors from the German Center for Diabetes Research (DZD), the Boston Children’s Hospital and the Harvard T.H. Chan School of Public Health call for more research about the relationships of obesity, disproportionate fat distribution and impaired metabolic health with the severity of COVID-19.
The authors raise the point that most of the studies that have reported comorbidities in patients with COVID-19 did not provide data on body weight and height, which are used to estimate adipose tissue mass, by calculating the BMI. In their Comment they also briefly summarize novel research findings, deriving in part from articles which have not yet undergone peer-review, indicating that overweight and, particularly, obesity may associate with a substantial risk of a severe course of COVID-19. Importantly, these studies suggest that this risk is independent of cardiometabolic diseases and other comorbidities.
The authors then discuss possible mechanisms explaining this relationship. Among them respiratory dysfunction in obesity may result in hypoventilation-associated pneumonia and hypoxia-induced cardiac stress. Furthermore, they highlight that not only the calculation of the BMI, but also the measurement of the waist circumference and of glucose and insulin levels, which can be used to determine the presence of prediabetes and insulin resistance, may be important, as these parameters are independent determinants of cardiometabolic diseases, pneumonia and mortality.
Fat is fat, right? Well, no. There is more than one kind of fat.
Visceral fat is stored in a person’s abdominal cavity and is also known as ‘active fat’ as it influences how hormones function in the body. An excess of visceral fat can, therefore, have potentially dangerous consequences. Because visceral fat is in the abdominal cavity, it is close to many vital organs, such as the pancreas, liver, and intestines.
The higher the amount of visceral fat a person stores, the more at risk they are for certain health complications, such as type 2 diabetes and heart disease.
I have just run across another study that backs up the blog mantra of eat less; move more; live longer and its corollary use it or lose it.
Health experts have warned for years that men and women with excess abdominal fat run a greater risk of developing cardiovascular problems. However, individuals with abdominal or central obesity are not the only ones in danger, according to a new study, reported by Elton Alisson | Agência FAPESP
The study found that physically active men who were not overweight but whose waist-stature ratio (WSR) was close to the risk threshold were also more likely to develop heart disorders than individuals with lower WSRs. Continue reading
Belly fat is very bad. It can literally kill you. I have a Page on it – What are the dangers of a big waistline? that contains a number of articles spelling out chapter and verse on its dangers.
Now comes Harvard Health Publications with more info on this weighty subject.
“Though the term might sound dated, “middle-age spread” is a greater concern than ever. As people go through their middle years, their proportion of fat to body weight tends to increase — more so in women than men. Extra pounds tend to park themselves around the midsection.
“At one time, we might have accepted these changes as an inevitable fact of aging. But we’ve now been put on notice that as our waistlines grow, so do our health risks. Abdominal, or visceral fat is of particular concern because it’s a key player in a variety of health problems — much more so than subcutaneous fat, the kind you can grasp with your hand. Visceral fat, on the other hand, lies out of reach, deep within the abdominal cavity, where it pads the spaces between our abdominal organs.
“Visceral fat has been linked to metabolic disturbances and increased risk for cardiovascular disease and type 2 diabetes. In women, it is also associated with breast cancer and the need for gallbladder surgery.
