Redefining Joy through Healthy Eating

The speaker has focused on cleaning up their diet by eliminating carbs, processed foods, and most sugar. They have faced criticism implying that their new diet must lack joy. However, the speaker feels much better and has realized that joy does not solely come from eating carbs and sugar. They discuss the concept of shallow happy (eating the cake) versus deep happy (being proud of not eating the cake and being healthy) as mentioned by Derek Sivers. This prompts the speaker to question what other sources of joy are missing for those who associate junk food with joy.
