One stupid thing to look out for is buying bulk snakcs/food items. If you look at the portion sizes for most snacks, it’s actually comically small. They do this so that they can put bullshit like 100 cal/serving, but the serving size is actually like 3 chips.

This is incredibly wasteful, but what I like to do instead if I want snacks is I’ll buy the pack of individually wrapped lunch sized snacks. So instead of getting a “family size” bag of Doritos, I’ll get the box of snack packs.

I get that it’s terrible for the environment, but it’s a lot easier to track how much of the snacks you’re eating. Instead of mindlessly downing a whole family sized bag of chips, you now see exactly how many calories you’re consuming…and you’re more mindful because you’re individually opening each package. You still get to have a treat, but it’s easier to be mindful of what you’re doing imo.

To be less wasteful, I suppose you could still buy these “family sized” bags of things, but then you’d want to immediately split the bag up into separate containers by portion size so you know how much you’re consuming.
