I know that lockdown has made some people put weight on. But others took the opportunity to do something about their weight. I know a few people who have lost 3 stone plus each since March. Their normal lifestyle, long hours and a commute, did not leave time to exercise, and lockdown gave them the opportunity to address that. We know that weightloss is 80% what you eat, 20% how much you move - but if you exercise it encourages you to eat better as well. Working long hours, which we do in this country, and shift work, make it hard to make healthy choices.
I do a daily walk, and I see two very overweight men who are visibly shrinking week on week. I think this time has encouraged people to look at their weight issues for health reasons. What you look like is going to be a factor but good health has to be the primary factor on watching your weight.
I am never going to be very slim, but I try my hardest to do the best I can for my body, which is the occasional treat but lots of healthy fuel and moving when I can.
Life is hard, being overweight and unfit makes it harder. In its extreme form, it disables. And that's without the detrimental health issues like diabetes etc. I know that some of my health niggles disappear or reduce substantially if I maintain a healthy weight.
We do have a personal responsibility to take care of ourselves, not push blame onto others. Some people have genuine health reasons why their weight is too much, but for the majority it is being weak willed and lax with regard to health. The food industry could do more.
We also normalise weight. If you live in an area where there are lots of bigger people, it becomes a norm. And there is a suppression of talking about weight (being a fat shamer). If we do not talk about it, we will get larger and larger. Kids will be getting fatter and fatter.
