This has nothing to do with slimming, but was originally intended for diabetics. A German style so popular in Britain that many drinkers think there is no other kind of "Pils". Carbohydrates are diminished by a very thorough fermentation, creating a relatively high content of alcohol (about 6 percent by volume) and therefore lots of calories. In German law, the alcohol now has to be reduced back to a normal Pilsener level (5 percent by volume).
