I use it regardless of IF or not when planning a diet. Provide a link.
Geoforce made a good statement; although the scales and measurement are objective and difinitive means to show statistical changes in weight, shape, or composition they are not the end all methodology to determining asthetics. Sculpting a physique is as much an art form as it is a science. Why I mention that is because there's an important subjective element to defining human form. What one person looks like at 160lbs or 11% body fat can vary greatly to the next person. Getting back on track, I often hear people freak out when trying lose body fat worry that they gained weight but never considered that the weight may be increase in muscle mass which is 3x as dense. In some ways, the IDEAL shift would be to lose boy fat, increase muscle mass while not changing weight or gaining. Theoretically this is possible on an IF diet (or any diet) but it takes time to dial in and find out what and how much you need to eat. End rant.
