"APA’s survey of U.S. adults, conducted in late February 2021 by The Harris Poll, shows that a majority of adults (61%) experienced undesired weight changes (weight gain or loss) since the pandemic started, with 42% reporting they gained more weight than they intended. Of those, they gained an average of 29 pounds (the median amount gained was 15 pounds) and 10% said they gained more than 50 pounds, the poll found."
61 percent could have gone either up or down, and 42% said they gained more weight than they intended, of those that gained some gained more than 10 kg, and a smaller fraction gained more than 50 pounds.
So, what does this say:
(1) that people should adapt their eating habits to their needs
(2) that it is possible to lose weight and to gain weight unintended (which is something that isn't really news, see also: weight watchers and the whole weight loss industry)
(3) that the study did not correct for what would have been the result of the poll had COVID not happen
(4) that the word 'lockdown' that you ascribe to the cause does not appear in the article text, but the word 'stress' does
and finally
(5) that you link to this article because you think it supports your statement above when in fact that really isn't the case.
