The number of Weight Watchers points in sushi varies depending on the type, portion size and particular combination of ingredients. Points can range from a half point for a single portion of sea bass sashimi sushi without rice to 13 points for six pieces of shrimp tempura maki sushi.
Rice is a carbohydrate and adds points to sushi items, which are typically made with lower-calorie seafood and vegetables. Deep-fried ingredients, avocado and fattier fish such as salmon and mackerel add extra calories to sushi.
Weight Watchers, founded in 1963, focuses on a scientific approach to healthy eating and weight loss. In 1997, the company introduced a points-based system as an easier way to categorize foods and keep track of daily food consumption and activities.
