According to Weight Watchers in the United Kingdom a Freddo Bar is worth two points. Weight Watcher points are a mathematical calculation based on the nutritional content of a food item.
According to its manufacturer, Cadbury, the Freddo Bar was invented by Harry Melbourne in Australia in 1930. It is shaped like a frog and became one the most popular chocolate treats in Australia. It was introduced in the United Kingdom in 1973, withdrawn in 1979, then re-introduced in 1994. Cadbury says it contains 100 calories, 5 grams of fat, 12.1 grams carbohydrates, 1.1 grams protein and 0.1 gram of fiber. WW Cheat Sheets says Weight Watchers gets the 2.3 points (rounded to 2) by adding the carbs and protein together, dividing by ten, and then adding one point for the 5 grams of fat.
