Small bite-size pieces are notoriously underestimated. Studies show 50–200% portion errors for calorie-dense foods (Almiron-Roig et al., 2013). These candies pack 522 kcal and 42.2 g sugar per 100 g — pre-measure your serving instead of grazing from the bag.

About this food

How should I track Peanut bar?

Peanut bar is high in zinc. The trickiest part about tracking Peanut bar is that small portions pack a lot of calories, and most people estimate sweet portions poorly. Research (Almiron-Roig et al., Appetite 2013) found that calorie-dense foods are underestimated by 50–200% when portioned by eye. Weighing on a scale takes the guesswork out. And here is the mindset shift that helps: tracking sweets is not about guilt. It is about awareness. When you log a treat honestly, you can plan around it and still hit your targets for the day.
