Well, my magical grainless diet worked...for a few weeks. Now I can't get myself to get back on it. And, what's more, I'm distinctly eating worse than before the grainless diet. I'm obsessing over food a lot (even though I'm eating plenty) and often eating completely unnecessarily, which I wasn't doing (much) before trying the grainless diet.
I feel like dieting is just a generally doomed enterprise, to the extent that we mean anything other than "trying to keep a general focus on eating in a healthy way."
Trying to force myself to eat a particular way or amount just seems to drive me bonkers and make me obsess about food continually.
Not trying to force myself to eat a particular way or amount seems to lead to weight gain.
Obviously I should change my environment. Unfortunately, I think moving to the 19th century would probably shorten my lifespan more than it would lengthen it.
