ELI5: If you were to only drink 3,500 calories, and not eat any calories, will you still experience gain in weight? What's the different between calories you consume eating versus drinking (like soda, a starbuck caramel frapuchino, etc)

calories are calories.  but some calories come with vitamins and minerals and fiber whatnot  etc that your body needs.  

if you eat 3500 calories vs drink 3500 calories and get the same vitamins and minerals and fiber whatnot etc it's exactly the same.
