According to the report by the World Health Organisation, no country where less than 40% of the population is overweight has covid 19 death rates above 10 per 100,000.
But if all of the persons in those countries who died from covid were underweight/normal weight – then being overweight would seem to protect against death from covid. But we don’t know the obesity rates of those that died, so no conclusion can be drawn other than countries with low obesity rates tend to have lower covid death rates (not that obesity increases the risk of death).
It is known that death rates from covid increase significantly with age, but if older people have a tendency to be overweight, this unsubstantiated conclusion could be incorrectly drawn from the data.
