A 2-day diet developed by British personal trainer Danni Levy as the Pyramid Diet : a cyclical scheme that alternates days with low carbohydrates, days with carbohydrates and days without carbohydrates. In this case, for the upcoming holidays, I wrote three articles on the same topic: a 3-day diet, a 2-day diet and the last one, tomorrow before Christmas Eve, for those who want to keep themselves light.
Here is the outline of the 2 day diet.
