I had a similar experience with the social pressure around eating and fasting. I’ve had people get upset with me for doing a water fast and not joining them in eating while we’d sit around a dinner table. I workout a good amount (running, yoga, weights, swimming) and they thought I was being crazy, or they just felt judged for eating. For me it didn’t even register that highly: I’d wake up, decide to do it for a couple days to see what the effects on my body were, and that’s about it.

Honestly the hardest part was from other people, the fasting part was fairly easy and made me feel great.
