My sister ate two cucumbers for dinner for two weeks. She had breakfast and lunch as usual, but she didn't eat meat dishes. She lost 7.5 kilograms in two weeks. Eat honey water and cucumber instead of staple food. According to a conservative estimate, she lost more than 20 kilograms a month. Now her sister doesn't eat cucumbers at night, but eats vegetables and a little rice. There is no rebound.
