Just putting this out there for discussion. I looked at obesity rates and Covid death rates for East Asian nations as compared to North America, Europe, a couple South American, Australia, and New Zealand. There were a total of 191 nations on the lists I looked at.
Ranked by lowest obesity rate
Number is number of deaths per 100,00 population
In parenthesis is the obesity rate for the nation
* I did not include every country, just a random sampling to compare obesity rate to Covid death rate
1. Vietnam - 0.04 (2.1%)
2. Bangladesh - 3.80 (3.6%)
6 Nepal - 4.18 (4.1%)
7 Japan - 1.46 (4.3%)
9 South Korea - 0.94 (4.7%)
22 Singapore - 0.50 (6.2%)
23 China - 0.34 (6.2%)
24 Philippines - 7.23 (6.4%)
30 Indonesia - 5.54 (6.9%)
52 Thailand - 0.09 (10.0%)
67 Malaysia - 0.96 (15.6%)
105 France - 63.59 (21.6%)
110 Brazil - 77.99 (22.1%)
111 Belgium - 120.45 (22.1%)
112 Finland - 6.61 (22.2%)
113 Germany - 14.46 (22.3%)
122 Russia - 21.68 (23.1%)
123 Poland - 23.18 (23.1%)

141 Ireland - 40.49 (25.3%)
146 Czech Republic - 52.42 (26.0%)
149 Lithuania - 8.42 (26.3%)
150 Hungary - 27.61 (26.4%)
156 United Kingdom - 75.89 (27.8%)
161 Argentina - 80.88 (28.3%)
162 South Africa - 34.63 (28.3%)
165 Australia - 3.63 (29.0%)
166 Canada - 29.00 (29.4%)
170 New Zealand - 0.51 (30.8%)
180 United States - 73.91 (36.2%)
Of the non-Asian nations, almost all of the nations with a death rate of <20 per 100,000 population are either isolated (Australia, New Zealand) or northern European (Lithuania, Norway, Finland). A couple of exception are Germany and Greece.
A simple scatterplot of the data.
