But this only tells half of the story — after all, we don't exist in a vacuum, especially in the summertime. There are tons of other outside factors that can affect your appetite, cravings, and feelings of satiety . For example, you might crave lighter, more hydrating foods over heavier or saltier ones in the summer because they taste refreshing when you're hanging outside in the sun. Or, you might not have time to eat a full meal when you're on a summer hike or sitting on the beach all day, so you opt for a few smaller meals over larger ones. On top of this, you might receive lots of messaging from diet culture telling you that you need to be eating lighter or less food in general in the summer. (Which, quick reminder, is absolute B.S.)
