I pray I'm one day able to afford to just go buy a cake for no reason. I might finally be able to gain a pound.

I think this is true for everyone

that includes you, the lurker reading this comment

Edit: oof, guess i struck a nerve.

I have found the only way I can not be obese (and I mean the lowest BMI I have had is 24) is the most extreme diets - keto and now carnivore since keto is too hard to stick to

Though I don't envy you. You have no clear signal that you're eating unhealthily, but suffer the same ill health that us fatties do if you do eat unhealthily

You need to pump iron and eat protein to gain healthy weight
