It's frustrating.
"Just Eat Less" is roughly the way to lose weight, but the problem is not that fat people are so unbelievably stupid that they didn't know this. I am sure for some people it really is that simple. Not us.
My weight has been a bit of a rollercoaster. I've never been terribly thin, but I've been "not technically obese" from time to time. I'm currently back on the downswing, but God, what a pain in the ass. It feels like gaining weight is incredibly easy and losing it is incredibly hard (and I do believe this is validated by the science, because you wind up with more fat cells when you first gain weight, which I guess is both relieving and terrifying.)
No matter how many attempts it takes to fix my body, I'm obviously going to just keep trying, because obesity is horrible for you in so many ways. It saps your energy, it's carcinogenic, it increases your blood pressure and risk of heart disease, but it feels like one of those struggles that is never-ending. I've improved my diet numerous times but it never feels like it's quite enough.
