I accidentally in your base

My way of dealing with the head squirrels is in a choice/responsibility sense. Your body shape has changed because of your lifestyle changing (admittedly without your consent) and you're choosing not to make the lifestyle changes necessary to change it completely back. You acknowledge that not eating (including in the sense your mother uses the phrase) isn't healthy, so you're choosing not to return to that lifestyle. You also are choosing not to put in the disproportionate amount of effort involved in changing something your body naturally reverts to if given the chance. (Disproportionate because that particular bit of flab is something natural to your age and gender, and I reckon the only reason you didn't have it before is that what you were in the habit of regularly taking into your body was so unnatural.)

Whether you make the choice not to put the effort into making changes is up to you: I think the point is that whichever choice you make, it makes sense to be happy about it. I know it's tricky - it took me over two years to stop regretting my choice to start eating again. But if it is in your hands, you may as well make the decision which will give you most happiness and then enjoy it. And if it isn't - if this flab is just what happens to Denny's body when he reaches this age - then you may as well not worry about it.

Easier said than done, I know. But I love you anyway, and I think I get it.
