"Knowing my Personal Rest Day Calorie Intake has given me faster results," said one satisfied user, who described the app as the perfect companion to their 5:2 diet.

If you've ever questioned how the recommended 500 calories for women and 600 calories for men on a Fast Day were determined, here's the breakdown. The figures are based on the principle that women typically require 2000 calories and men 2400 calories per standard day. Therefore, on a Fast Day, one should aim to consume a quarter of the daily recommended caloric intake.

However, these values are only general approximations. To optimize the effectiveness of your 5:2 Fast Diet experience, it is advised to consume a quarter of the calories necessary to maintain your individual weight. This value varies for each person, factoring in gender, age, weight, height, and typical activity level.

The calculator app offered is designed to help you accurately determine your Rest Day Calorie Intake and subsequently your Fast Day intake for a tailored approach.
