Ask HN:What kind of diet will you recommend to a late night coder?

Since last month I have changed my working hours due to day time distractions. Now I work from 11:00PM to 5:AM morning. One thing I noticed that my weight got reduced upto 1Kg. One of the reasons I find that after dinner I don't eat anything for the whole night and then I sleep for 6 hours after 5 AM which makes fasting of around 10 hours. What kind of meals should I have while working in night? TIA
