Weight loss most effective for me is the 2-5 day fast. Males two days out of the week 600 calories no sugar no carbs. The other five days eat anything you want. Females 500 calories no sugar no carbs two days out of the week the other five days anything you want. Works best if fast days are a few apart not together.
I have issues with gluten here in the US and since doing this fast they have diminished. It really is not a diet more a lifestyle as once you reach your ideal weight you fast one day a week to maintain if you gain go back to the two day fast. It is call the Fast Diet and it works, not always easy but it works.
