Thanks to the healthy fats and fiber it contains, eating avocados is linked to improved satiety, according to results of clinical trials. One study showed that adding approximately one-half of a Hass avocado could influence satiety over a subsequent 3 and 5-hour period in overweight adults.
An easy way to include avocado in your snack rotation is by eating guacamole. And using a veggie as your guac vessel, like celery stalks, gives your body even more satiating fiber to help you feel full.
Greek yogurt and skyr are two dairy-based options that are packed with satiating protein (one serving can provide around a whopping 17 grams of protein), and in their natural state, are low in sugar (of course, some brands add sugar, which is something that you should look out for). Greek-style yogurt is typically higher in protein than regular yogurt, which is one reason why this snack is so appealing. Topping your low-sugar yogurt or skyr with chia seeds or ground flax seeds can make this snack even more filling, so be sure to keep that in mind.
