Hey there! This WOE works in different ways for different people. I can lean out if I keep my carbs and salt intake low, but my friend has to watch her calories and her carb intake meticulously otherwise she won't see any changes. Playing around with what your body responds to will be the best indicator for the path to follow. I also like to fast for 14-16 hours a day before I eat which seems to help with my digestion immensely as well as my leanness.
Congratulations on finding this lifestyle and good luck!
