Hey!
The fact that you are feeling uneasy about it probably means you're ready to start putting the brakes on the food indulgence. Follow that lead!
It's probably the increased exercise that's helping you continue to lose--and that's good--but you know that if for some reason you have to start skipping the gym... like school gets really amped up... that your food choices are going to be critically important. You can do the math!
Make some better choices... if that's what you mean by not eating in a healthful way...
