How high is too high for Protein??

No, it's not bad to be over on your protein. It is possible to get too much, but your carb/protein/fat ratio doesn't have to be exactly what they recommend. In fact, if you go to the "My Home" tab and select "goals," at the bottom choose "change goals" and select "custom," you can change the ratios. I have mine at 45% carbs, 25% protein, which works much better for me than the default 50% carbs, 20% protein.
