I know that eliminating grains and processed sugar are not enough for me to lose weight, but eating them only makes matters worse for me.
The upshot is that you have to try it and see if that alone works for you all the way to your goal and into maintenance. If not, you might need to find additional ways to help get things moving in the right direction. But keeping excess starchy carbs (grains and other sources) and processed sugar at a minimum will likely help.
