I'm half-way through my second round doing more exercise/building muscle and my appetite has majorly increased from before. I'm curious if other transformers have had this experience. Any advice?

Yes we have had transformers experience this before especially as they lose fat and start to gain more muscle. It's ok to increase your caloric intake if you are where you want to be with your fat %. If you still have fat to lose we recommend adding an avocado to your meals to fill you up.
