I'm on a low carb, high protein diet plan and need to lose fat. Where would I want my BG range to be? The reason I ask is because some people say that high glucose is bad for losing weight but some say it's ideal

. But many people I've spoken to say that low BG is very bad for losing fat since the glucose you take in to raise your levels gets stored away.
This is my personal opinion, but do NOT worry about your BG levels when working on fat-loss. If you maintain a healthy low-carb diet and exercise, and take prescribed meds, your BG levels should be well-controlled. And so you want your BG to be in that 'normal' range, under 7.8 (140) 2hrs post meal, and under 5.5 (100) fasting.
Exercising while having low blood glucose will, in most people, cause the liver to respond by secreting more glucose (stored in the liver as glycogen) and raising your BG levels to compensate, and give your body fuel. If you start the exercise at higher BG reading, the BG that's in your system is typically utilized as fuel without the need for the liver convert glycogen to glucose and secrete it into your system. For most people (without liver damage) once you've burned the blood glucose and start to get low, your liver responds by outputting more anyway.
If you experience hypo's (low BG) then you should certainly have SOME complex carbs in your system prior to exercise, and you may need to eat during exercise.
Regarding fat-loss. I personally believe fat-loss is best accomplished by a low-carb, high-protein diet combined with BOTH aerobic exercise and resistance straining. The goal is to eat healthy, eat often (5-6 meals per day, similar carb/protein/fat ratio), maintain a slight calorie deficit (no more than 500cal/day deficit, in my opinion, to avoid the 'starvation' syndrome), and exercise.
Regarding the two types of exercise: The resistance-training will increase your muscle mass, which in-turn increases your metabolic rate, helping you burn fat. The aerobic exercise, when done at the proper intensity level (varies by individual, but usually low to moderate intensity) and for the proper length of time (20+ minutes per session) will use more blood-borne glucose and FFA (free fatty acids, derived from adipose tissue) for fuel rather than muscle glycogen. (Short, intense exercise usually burns muscle glycogen for fuel, rather than the glycogen stored in your liver or the FFA's.)
The combination of the exercise and fat-loss will help your BG levels in the long run.
