Because if you eat out every day, you will gain a lot of weight, especially fast food, which is high in salt, oil and fat. If you eat it regularly, it will do great harm to your health.
When cooking at home, you will adjust the salinity and taste of food according to your own taste, and cooking at home will also reduce your own expenses. At the same time, it is relatively healthy, not high in oil and salt, which is extremely beneficial to people's health.
So I suggest that cooking at home is more appropriate if possible. It is not only economical and cost-effective, but also good for people's health, so as to avoid eating out every day, which invisibly increases their economic burden.
Many people around me never eat out. Cook at home at work and take it to the company to eat.
