The carbon water cycle system is divided into three links:

1. High carbon steel day: High carbon steel day means that you need to ingest more carbohydrates, and the total calorific value exceeds the usual calorific value, but the overall intake of substances should meet the needs of the human body.

2. Mid-carbon Day: What is needed for Mid-carbon Day is that the intake of breakfast, lunch and meals is normal, and the intake of dinner is low, and only 3g of fruits and vegetables are eaten.

3. Low-carbon environmental protection day: Low-carbon environmental protection day is more difficult. Only eat breakfast, and be sure to eat high-protein food. Chinese restaurants and dinners only eat 3g fruits and vegetables.
