I didn't eat one whole avocado in one sitting. I cut it in half and had one half at lunch or dinner, and one-half for an afternoon or after-dinner snack topped with salted sunflower seeds (my fave!) or smeared on toast with sliced cherry tomatoes. It added creaminess to salads and buddha bowls, and by the the end of the evening, after having had one avocado in my belly, I actually did feel more satisfied.
I also noticed that because avocados are rich in fibre, it helped me out in the bathroom. Plus, I didn't get sick of avocados, even after a week and a half into my little experiment. I actually began to crave them more.
