A. Our weight loss calculator is a useful tool for setting realistic goals, tracking progress, and making informed decisions about diet and exercise. However, it's important to remember that weight loss ultimately requires consistent effort, dedication, and adherence to healthy lifestyle habits. The calculator serves as a supportive tool in your weight loss journey but it should used in conjunction with a balanced diet, regular exercise, and other health behaviours for optimal results. We advise pairing the use of the calculator with our Affordable Fitness App Plan to see meaningful results.
