lose weight

Since my son was born 16 months ago, my sleep becomes unstable and mostly shorter than 5 hours a day, continuously. As a result, my weight dropped dramatically, from about 85kg to 72kg now, in this period. Amazingly, I don’t feel exhausted or too tired. And I caught less cold, had less other illness, etc. I think losing weight does help one.

I am now 85kg. I have been 85kg for 20 years. I plan to lose my weight gradually. 75kg is an optimal number but not realistic by next month. Let me achieve it step by step:

1) 82kg by the end of 2009
2) 79kg by the end of 2010
3) 75kg by the end of 2011
