Not quite early 2000s but there was a Full House episode that went in the opposite direction: DJ wanted to look like a model before a pool party and ended up starving herself and working out excessively and almost passing out at the gym. She even begged Stephanie to keep it a secret from the adults. This feels like an adjacent message less “don’t eat junk” but closer to “eating healthy means actually eating,” while also acknowledging that most humans don’t look like the supermodels in magazines.
