I'm sure no expert, but perhaps you should go back to the Spark beginning and let Spark recalculate your recommended calories.
You don't say what that level is right now. In the meantime, it looks like you might be wise to eat at the UPPER range and be sure you get enough protein.
It's pretty well accepted that you must fuel your body or it will betray you. You don't want to start burning, and therefore, losing muscle. That can happen if you over-exercise and under-fuel.
Burning muscle can lead to some pretty significant medical problems affecting the kidneys and other body systems.
I'm sure that's the primary reason Spark sends out those warnings.
Not trying to scare you here. Not at all. But it might be time to "tweak" your program so you get where you want to go without taking any unhealthy detours.
Having said that, may I add a HUGE high-five on your dedication. I could use some of that myself. Exercise is a big "issue" for me and I have lots of room for improvement in that department...lol
It's not that some people have willpower and some don't. It's that some people are ready to change and others are not.
