As the saying goes, we don't eat at noon, so we lay people at home should conform to nature and not be persistent. Otherwise, how can you learn Buddhism when you burn your body?

This should be done step by step, not after noon. It is best to enter that state naturally with the gradual improvement of age, physical strength and practice.

That's what I'm saying.

If you are suddenly hungry, your stomach will soon go bad, and then your intestine, spleen, liver and kidney will be slowly affected. What should I do?

Don't be persistent, at most beginners can eat less at dinner, or eat some fruit and vegetable soup. It's already very good. Can keep fit.
