Congrats on your purchase and enjoy your adventure into STS. When I started STS last Spring I read through numerous previous forum threads and some people did mention increased appetite, and a couple of women complained their weight increased. I did not experience this myself, but like you, I did increase my protein intake and I still lost weight and inches in Meso1. No weight loss in the other meso cycles though (but did lose inches). I suspect I was adding muscle, so I didn't expect to lose anything since I didn't eat deficit calories. Trust the process and enjoy the journey
