I don't use the term fasting either, mostly because it feels like an exaggeration of what I do. I tell people I don't snack, because I think that's had a huge impact on my weight management. And I sometimes tell them I just have coffee with a bit of cream for breakfast.
If they give me grief about that (horrors! the most important meal of the day!) I'll blather on a bit about IGF and then ask them to show me one piece of peer reviewed literature that shows a negative metabolic effect of skipping breakfast. I work in the R&D department of a biotech company so an appeal to the literature generally shuts people up, even if they're not interested in the facts.
I think most doubters would be interested Michael Mosely's fluffy little documentary, "Eat, Fast and Live Longer". It's very non-threatening.
