Fitness meals used to be a good industry, with many shops, but not many survived now. First, because the person who made it didn't take it seriously, and second, because the person who ate it didn't insist. Most of them are fresh for two days, so I stopped eating them. They should have been a sunshine industry, but they are not ready yet. It seems that the initial investment is still relatively large. If you want to do well, you need to stick to it all the time.
