JunkDrawer, Hi, I set up my calorie/nutrition needs when I was barely working out 2 yrs ago. I've increased my exercise by distance, minutes and weight and I also keep getting these "warnings". I had the same question...how do I change the # of calories I am suppose to eat. My calorie range is 1200-1500 currently. My trainer says that's too low. I don't know what to do. Hopefully somebody will respond. Very frustrating! Good luck. Awesome that you are losing weight. If I get to the bottom of this, I'll let you know.
