Hi Amanda If you are not eating enough then your BG will be low at times. If you still have weight to lose, then I think you are on the right track. When you reach your weight loss goal you should probably increase your fat and protein intake a bit in order to maintain that level. If you are having a lot of loss of appetite symptoms you might need to see your doctor about it as there could be something else going on. But in general, low carbing and losing weight could well mean we are not as hungry as we used to feel and that is ok.
