i did this. i lost 4 pounds in the first 2 days. i lost about 10 pounds. i didnt work out. i didn’t believe that i would gain all the weight back from my body needing to eat essential foods,, like sugar & carbs, but i did. the weight i gained back wasn’t as noticeable as before. ok that sounds weird, but i used to have rolls, i did this, and i gained weight back, but with no rolls. so i would keep caution,, bc this could turn to an eating disorder, like me.
