Rapid Fat Loss Calculator
Enter your current weight and estimated body-fat percentage to get a clear daily macro range without complicated math.
Your information
Use an honest estimate. It only needs to be close enough to choose the right starting category.
UnitsNot sure? Use a smart scale, handheld tester, gym assessment or comparison photos. Home devices are not perfect, but they can provide a useful starting estimate.
Your daily starting range
Protein is the anchor. Aim inside the range instead of chasing one perfect number. These are total carbohydrates, not net carbs.
GET THE FULL RAPID FAT LOSS BLUEPRINTA smart scale or gym assessment is enough to select a starting category. Use the same method under similar conditions when checking again.
Enter these targets into MyFitnessPal, Cronometer or your preferred tracker. Verify every new entry against the food label.
Run the calculator again only after your weight or body-fat category changes meaningfully, not after one random scale fluctuation.
