How should I track Reese's Bites?
Reese's Bites is a good source of magnesium. The trickiest part about tracking Reese's Bites 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.
