I keep erasing and re-typing this because I am having trouble expressing what I am trying to say, but here goes. Unpopular opinion alert (potentially): Some moderation of calories is necessary in an environment full of cheap, tasty, calorically-dense food.
I want to be very clear that I know women are held to beauty standards which are actively harmful to them. Yes, men face pressure too, but while they are pressured to be athletic, women are pressured to be as thin as possible (while still having a large butt and breasts, natch). It is unhealthy and unfair. And it does indeed cause women to starve themselves in the pursuit of that ideal.
That all being said, I spent a lot of time in my younger years following the popular fat acceptance bloggers, and I have noticed that there is an all-or-nothing mindset with regards to calorie counting (or even just the idea that one should monitor ones intake) which is common within the movement. I believe it is a reaction to the tremendously unrealistic and harmful dieting advice out there, but it is unrealistic and harmful in its own way.
Keeping an eye on your food will not transform you into a joyless husk consumed by anxiety and self-hatred. Losing weight can be as simple as eating 100 fewer calories per day than you normally would; that's what, 2 oreo cookies? You don't have to choke down 7 spinach leaves for breakfast, lunch, and dinner. You don't have to swear off any of the foods that make life worth living.
I don't want to go into it too much (this is long enough), but I have seen various family members going through health issues not because they are lazy, slovenly, gluttonous fatties, but because they live normal lives in an environment with lots of great food. Despite the fact that a couple of them are fairly active, their weight is still making life more difficult than it needs to be. My aunt, especially, refuses to consider dieting because she just knows that it's a one-way ticket to an eating disorder, but for the others it's more that they are convinced that 1) cutting calories is, by definition, torture, and 2) it is impossible to lose weight unless you are significantly depriving yourself. Maybe if your goal is Kate Moss, yeah, but if you're just looking to make flying in coach a little more comfortable then that is a goal within reach for the vast majority of people.
Fat is definitely a feminist issue, but I wish we didn't have to throw the baby (of health-consciousness, I guess) out with the bathwater (... of unhealthy beauty ideals and practices). Being aware of what you eat isn't the same as being ruled by it.
Apologies for the ramble.
