Scientists in Sweden analyzed health records in over 279,000 subjects who had prior documented fitness and body fat screenings.
They found strong, independent associations with low fitness levels and higher belly fat with increased odds of severe disease.
Since the media doesn’t cover these studies, I thought you’d find them helpful.

01:46 Increased levels of underlying health conditions are independently correlated with the risk being hospitalized and dying.

02:30 Physical inactivity is associated with a 32% increased risk for being hospitalized from SARS COVI2. 10% of COVID hospitalizations were linked to physical inactivity alone.
03:30 People who were physically inactive in the 2 years leading up to COVID 19 outbreak, had a significantly higher chance of being hospitalized, admitted to the ICU and dying from COVID 19, compared with those who reported 150 cumulative minutes of exercise over the course of a week.

04:45 25 to 30% of skinny people are metabolically obese, with fat in and around their organs. It is ectopic fat deposition. Visceral fat is independently corelated with increased risk of many diseases and poor outcomes with COVID 19.
05:26 Visceral adiposity is associated with severe COVID 19. Subcutaneous fat was not.

06:40 The rate at which children have become overweight has more than doubled since the COVID 19 outbreak.
07:33 Exercise reduces the risk of developing the underlying health conditions that are associated with poor outcomes.

08:00 Many of our immune cells are susceptible to cellular senescence, irreversible growth arrest. Senescent cells release biologic pheromones, attracting other cells to become senescent. Senescent cells accumulate during ageing and accelerate ageing.
11:55 The COVID 19 death rate reported in the Sweden study was .03%, even with open schools and no mask mandates.
12:49 People who contracted COVID 19 in Sweden generally had higher BMI, waist circumference, blood pressure and increased numbers of underlying health conditions. They were often daily smokers, had lower VO2 max scores, and less favorable exercise patterns compared to those who did not become ill.
13:38 Being overweight was associated with a 2-fold increased odds, and being obese or severely obese was associated with a 3-fold increased odds of having a severe COVID case, compared with those with normal waist circumference.
14:16 Underlying health conditions had the greatest increase in odds, 1.88 for one diagnosis, up to a 4.55 greater increased odds with those with 4 to 5 chronic diseases.
14:41 High psychologic stress was associated with a 1.36% increased in odds of severe COVID. Daily smoking increased odds for severe outcomes .6%.
15:00 There are strong associations of several lifestyle related risk factors, including cardiorespiratory fitness, being overweight or obese, perceived stress and high blood pressure with severe COVID 19.
