It can be done whenever the need arises, but no more than three days in a row: if we have eaten too much, if we have a swollen stomach, this flat stomach diet proposed by coach Jill Gardner is for us . For three days we say goodbye to packaged foods, foods containing extra sugars, foods that are too fatty or too salty, dairy products, products containing refined flours and gluten, and the stomach will immediately seem flatter. By eliminating the foods that cause digestive stress, inflammation, gas, water retention, we can lose a pound in three days and get rid of some excess toxins.
Among the rules to follow,allow twelve hours of fasting between dinner and breakfast the next day; chew for a long time; drink a glass of warm water with lemon juice and fresh ginger before breakfast and another two or three glasses of this same water during the day; observe relaxation exercises for ten minutes, e.g. breathe deeply, stretch the muscles by stretching.
