ffs I get so so pissed off with this. It is such lazy lazy thinking.
Smoking is an ACTION. The result of which is crap horrible lungs and illness/death. Once you have stopped smoking, people think you are fine and stop shaming you. Just imagine if people's lungs were actually visible and we only stopped shaming people when their lungs were perfectly healthy again (like never or at least a very very long time after quitting smoking!!)
The action associated with being overweight is overeating/low activity. People can be overweight and have stopped over eating and be exercising. This is because they may have changed their ACTIONS . It is just that the damaged caused to their body is visible (ie excess fat) and sometimes not completey reversible.
Shaming people for being overweight is like shaming people
I personally think it is a very good idea to stop people who are generally a normal weight from becoming over weight in the first place, so mentioning if someone who is a normal weight seems to be getting bigger is not a bad idea as people can tackle it early before it gets too bad. Sometimes people don't always notice if they are putting on weight in the early days, especially if weight goes on evenly all over your body.
However once people are really overweight though, this is counter productive as they are past the point of just being a bit careful for a few weeks to get back to normal. The damage to their body has been done. So being critical and shaming has no value at all in this example.
Instead of fat shaming overweight people who may well be tacking their actions anyways, it just might not be obvious from their weigh yet. I have been fat shamed after losing 4 stone over 8 months as I was still very overweight despite not overeating and exercising regularly for 8 months. Try that for being suicidal after that effort.
What ex smoker would be shamed, 8 months after quitting because their lungs were still damaged!!?
We need to stop people getting overweight in the first place. That is the time for a bit of tough love. One the damage is done, people need help and support to minimise the damage they have already done to their bodies, not demonising for it.
