If you’ve ever felt like “I don’t eat that much, but I’m not losing weight,” chances are hidden calories are creeping into your diet. These aren’t obvious meals but the extras that silently add up:

• That splash of cream in your coffee (50 calories).
• A handful of nuts while cooking (150 calories).
• Salad dressing at lunch (200 calories).
• Evening glass of wine (120 calories).

Individually, they don’t seem like much. But over a week, those hidden calories can add up to 1,500–2,000 extra calories— almost a full day of eating.

Studies in The American Journal of Clinical Nutrition (2010) show that people consistently underestimate calorie intake by 20–30%. Our brains simply aren’t good at accounting for snacks, drinks, and small bites.

Fastry’s intermittent fasting approach helps eliminate many of these mindless calories. When you’re in a fasting window, there’s no debate about “just a bite” or “just a sip.” The rule is clear, and the clarity removes temptation. Instead of fighting willpower all day, you create an environment where hidden calories simply don’t exist.
