Welcome to Steemit. Interesting post. I know people eat very differently in different parts of the world. In India some people have big meals at 10pm. People have also eaten very differently based on food availability. If people were not well adopted to go for long periods of time without food we wouldn't be here. Most of our ancestors would have starved to death. People fast up to 30 days without food and to starve, you can go with very little food for several months. I find your once a day eating habit interesting. Having done a more traditional fasting -going one to several days without food- can get some very weird reactions in the United States. There is definitely something to it as you feel differently.
