Learn how to read nutrition facts labels like a sports dietitian: decoding serving sizes, net carbs, added sugars, and ingredient order.
Front-of-package marketing claims—like "High Protein," "All Natural," or "Keto Friendly"—are advertising slogans, not nutritional facts. To truly know what you are putting into your body, you must flip the package over and inspect the Nutrition Facts panel and ingredients statement.
The Serving Size Manipulation Game
Manufacturers frequently manipulate serving sizes to make an unhealthy food appear low-calorie. A small bottle of beverage or protein bar may list 150 calories—until you notice that the container contains "2.5 servings," bringing the real total to 375 calories.
