It is not possible to determine the number of calories in 23 Weight Watchers points because the points system is based on a foods unique nutritional content, not just its calorie count. The points assigned to a food or beverage are based on the amount of calories, sugar, protein, and saturated fat it contains. The point values for foods are calculated by looking at their protein content, fat content, calories, and other factors. Therefore, the number of calories in 23 points will vary depending on the nutritional content of the foods chosen. However, according to a Reddit post, roughly each point is about 33 calories, so 23 points would be approximately 759 calories. It is important to note that the Weight Watchers program also encourages the consumption of zero-point foods, which do not count towards a persons daily point allotment. The program assigns a set allocation of daily and weekly points to each person based on their gender, current weight, age, height, and other factors.
