It works quite well. Some of Mei-Shun’s friends carry out 8-hour diet, gave her a hint for an original method. They are allowed to eat anything, anytime within 8 hours. Other 16 hours would be used for digestion and rest for intestinal tracts. Sounds logical, yet the essence seems to be in another factor: those watching weight tend to eat less than before. That is why Mei-Shun decided to allot 8 hours to carbohydrates.
