If you're ever feeling bad about your weight, particularly when looking at old pictures of beautiful, slim people - don't.
The rise in obesity is strongly correlated with the decrease in smoking rates. Basically, post-1964, we stopped lighting up and started reaching for the potato chips as an alternative way to self-soothe. Combine that behavioral change with the increased availability of junk food and prevalence of eating out and you've got yourself a three-punch combo that makes staying trim a constant struggle (at least for us Americans).
I mean, you can't even go to Staples, an office supply store where they sell paper, without being confronted with a wall of junk food at the cash register. Same for the FedEx store. Why are they selling Pringles next to the packing tape? On my old commute (which was long and stressful and topped off a long and stressful day at a job I didn't particularly like), I passed probably a dozen fast food restaurants and another half dozen gas stations stocked to the gills with junk food every. single. day. How long could I resist that level of stimulation and advertisement encouraging me to bliss out with a bag of cheesy popcorn or a crunchwrap supreme?
So if we're not suppressing our appetites with cigarettes anymore (cause we don't want cancer, cardiovascular diseases, emphysema), and we're exposed to more calories/day than any previous generation has ever experienced in the history of humankind, then you probably shouldn't feel bad about your weight.
Go ahead and eat healthy, exercise more, get fit, etc. Those are all great things. Just don't let yourself fall into a cycle of despair and guilt over weight issues or for caving into a junk food craving, because the odds are stacked against all of us. It's really unsurprising that it's an issue given the conditions. It's not all about free-will. You are the product of the society and culture you live in, and right now things are out of whack.
And this NOT a PSA to encourage you to smoke, which is infinitely worse for your health than carrying some extra weight. This is just a reminder to be kind to yourself.
