Overview & Core Concept
Dietary tracking provides objective awareness of energy balance. Studies show individuals who consistently log meals lose more weight and maintain it significantly longer than non-trackers.
Our tracker runs natively in your browser, keeping your daily food log completely private with zero account creation or subscription fees.

Pro Tips & Critical Pitfalls
- Weigh foods raw: Cooking methods alter moisture and water weight substantially (e.g. raw rice vs cooked rice).
- Do not forget cooking oils, sauces, and coffee creamers—these are the most common sources of hidden calories.
- Using measuring cups and spoons instead of a digital gram scale (a "tablespoon" of peanut butter is often 25g instead of 16g).
