What are your workouts consisting of?

If your glycogen stores are constantly depleted, your body is probably breaking down muscle into glucose to fuel your workouts - yet another reason not to eat a chronic low carbohydrate diet. You could try two things and see if it helps your blood glucose levels:
1.) Stop eating so damn low carbohydrate. A serving of fruit or starch may keep your liver and muscle glycogen partially replete, allowing for better workout performance, less muscle catabolism and more stable blood sugars while fasting.
2.) Take BCAA's 30 minutes pre-workout to spike your insulin and protect muscle during workouts.
Low level cardio typically has the opposite effect on insulin and blood glucose, bottoming them out.
You may want to consider carb cycling to improve your blood sugar numbers. On heavy lifting days, eat more fruit and safe starch to help improve your insulin sensitivity. Avoiding carbs promotes insulin resistance and could stand to hinder your recovery - it's hard to fix your glucose metabolism when you never exercise it. On days you don't lift, keep carbs very low and do some low level cardio to further bottom out insulin. You may want to get your body used to low levels of insulin and high levels of insulin in healthy patterns (i.e. no snacking and eating real, whole foods) to help improve your insulin sensitivity. Never spiking blood glucose or insulin gives your body little reason to fix that metabolic pathway. You'll have to experiment to find out what's too much or too little - no BG spikes hinder recovery, but too many BG spikes could as well. You could probably judge what's healthiest by your level of fatigue vs carb intake.
Don't put your trust in anyone on this forum, including me. You are the key to your own success.
