In a world that operates 24/7. how can second and third shifters develop a healthy eating lifestyle? i find it hard to eat more than twice a day.

Create own routine: First, it's not necessary to eat more than twice a day. It can be a challenge to develop a healthy eating lifestyle no matter when you work. Shift work creates health challenges so it's best to try to keep a steady schedule even on days you don't work. It is hard to get healthy food at most restaurants; best to make your own meals at home. See http://tinyurl.com/nq4sx63 for info on diet & health.
