Thank you so much for your message! Is very interesting and deep question! Longterm fitness motivation is always great and is great to plan fitness as a lifestyle in order to maintain consistent results. Rather then quick fix solution! There are 2 strategies available, steady weightoss is good solution. Some people choose this. But I for example advise do it in 3 steps . 1 - transform, 2 reverse - backup diet slowly to "normal" 3 maintain - reintroducing foods and maintain achieved weight!
