I am 5.8, 135 lbs. I'm convinced I can be lose another 10lbs if I cut down slightly, and keep running twice a week. Down to my college or high-school weight if I drop another 10 lbs.
It would reduce my cardiovascular risk, improve my running (easier on knees).
Am not a Muslim, but this month of Ramzan (or Ramadan) does inspire me to try some light fasting.
Nothing severe, no extremes for me. Happy with incremental, over a period of time, changes.
