it's not fat shaming to state a simple fact.
What doesn't work is to pretend being overweight is "normal" and to be proud of.
Very true, and it is quite bad (I think) that 'big' (ie, obese) is promoted as beautiful, and good for women to be, and that size 22-24 plus women are perfectly OK as they are, because it is unhealthy to be so big.
I also hate fat-shaming though, so it's finding that middle ground, to encourage people to try and be fitter and more active, and lose weight safely and slowly (and to try and maintain that lower weight.)
I also agree with a pp that it doesn't help that we are being told by the experts that certain things are healthy and good for us one season, and then the next season, it's bad for you. One example is wine.. 'Wine is bad for you, wine causes cancer,' one news report will say in the Springtime... Then by Autumn, a news report comes out that says 'wine is good for you and extends your lifespan by a decade blah blah blah...'
So annoying, and no-one knows where they stand. I just eat whatever the fuck I want now.
Purely anecdotal I know, but I have older family members who have knocked back whiskey and wine for 50-odd years, regularly ate fatty high-carb food, meat, chocolate, biscuits etc etc etc, and smoked for some years, (maybe 10 a day now as they are so expensive,) and they are now 70-90 y.o, fit as fiddles, fairly slim, and more active than some people half their age.
Interesting to see how the fry-up (in the post from 10.43 by @TwelveLeggedWalk ) is half the calories of the 'healthy' breakfast with muesli and smoothie. 
I think (and this is only my simple and humble opinion,) that one of the reasons for obesity is women being made to feel they could 'have it all' in the 1980s, and being made to feel like some kind of failure if they weren't a successful career woman, didn't own their home, and weren't a brilliant super-mom.
With all this came the advent of widespread microwave-oven use, and ready meals. So these became the 'norm' as many women didn't have time to cook from scratch as they were so busy and frazzled.
And there's no way men would do the housework and cooking, (most of them anyway.) So as I said, many women were frazzled, and stressed, and chasing their tails all the time, trying to do it all, and dished out ready meals/microwave meals. In addition, they were more likely to have a car, so by the 1990s, women AND their kids didn't walk so much.
Back in the 1970s (and before that,) many women I know didn't drive. In fact, I only knew a couple who did, and most of them didn't have their own car. Some families had only one car, some families had none at all. Everyone walked to school and work, many women didn't work (or only worked 10 hours a week,) and all ate cooked-from-scratch meals.
Society, and all its pressures on women especially are one of the reasons many younger people (and children) are obese now IMO. Not necessarily the MAIN reason, but ONE of the reasons...
I also don't think it helps anyone, to come out with snarky and sanctimonious remarks like 'well I work full time, and I manage to 'cook from scratch' and batch-cook super-healthy meals for MY family.' It just makes those posters look smug and condescending..... and like they think they are more superior somehow..
