Looks like we have some bull*^$& in this thread... Stupid fads that don't work because nothing is "one size fits all" when it comes to fitness. I bet some of you are "certified" Crossfit instructors too, right?
OP, what were you doing when you were losing weight before? Do it again... Put yourself in a deficit and start working out again. Don't stop working out for two whole months and expect to lose weight, especially after you've already lost some. If/when you hit a plateau, change it up. Workout harder or do something different, maybe something you've never done before. Your body WILL adapt to whatever you're doing and eventually you'll stop losing.
