This started out as a reply to a reader's comment but it got pretty long. I also feel that there are things which many people might want to eavesdrop on. So, the reply is here as a blog. Hi yuhui, I like your phrase "super bloomers" more than "late bloomers." Before I continue, I want to caution you about having only one meal a day which is the most extreme form of intermittent fasting. I tried that for a few months last year and lost so much weight that my mom got worried.  She told me I looked like Chew Chor Meng who was quite ill. When I met Kenji and Victor, my friends from The Fifth Person, about 6 months ago, they were shocked by how thin I was. Anyway, I have since gone back to having at least 2 meals a day, eating within a window of 6 to 8 hours each day. So, I am still doing intermittent fasting...
