I dont think people overeat because food is tasty exactly (tastiness likely being a surface manifestation of deeper biochemical causation) - i think the food changes how we partition the energy we eat and hunger results. Of uour fat storage algorithm overprioritizes gat storage, more energy is taken from circulation resulting in hunger and low energy to replace what fat storage is taxing. I think fat people are as hungry when they are overeating as I am when staying lean. Its native biological differences and native susceptibility to biochemical changes caused by the food itself unmasked by a food environment. I'm pretty sure i find junky food as tasty as anyone else but I genuinely dont have the sensation of willpower being exercised to avoid it. Im pretty bad at sitting around hungry but I'm lean. My exercise mostly just makes me hungrier, which i dont white knuckle through.
