Figuring out what I am doing right

I have Lost weight in the last two weeks..I am talking seriously 10 TEN! pounds here! Is it the fact I have been mindful of increasing my Vegan Protein diet? Is it that I added the Tiger Hill walk to my routine? It definately is not lowered stress or more sleep.I want to pin point this so I can keep it up! !(199 # Here I come! ,but we all know the ultimate goal is 180 #)
