I started doing it to lose weight. I lost 2lb per week for a period of 10 weeks. Since then I have continued doing it, but much less strictly. I don't eat breakfast and try to have a small lunch (like 2 pieces of toast), then I have a very large dinner at around 6pm. I honestly think I feel much better in the mornings, and I don't get sleepy in the afternoons. The way I started was to slowly push back the time I ate something at the start of the day. At first I didn't eat until mid morning, then after a few days I didn't eat until lunch time, then mid afternoon. After a week or so I was no eating anything until my evening meal.

In this case Google, Facebook, Apple and Amazon are obviously major threats to national security and should be banned from operating in the EU and USA.
