Apologies, I see the answer I tried to post was never published. Firstly, congratulations with your weight loss, it must be a great relief and wonderful sense of achievement. A low carb diet is very likely to make one feel less energised, sometimes tired and even shaky as you describe. A blood test would be the best indicator of a magnesium deficiency, but a fast and more cost effective option than a blood test to consider is to take a magnesium supplement and monitor your symptoms over 5 days of taking the supplement.
The nutrients your body may lack on a low carb diet, that may result in fatigue-like symptoms include:
- Magnesium (increase your intake by including red meat, dark green leafy veg such as broccoli, spinach, baby spinach and rocket, as these still are low carb); Supplement your diet with a magnesium supplement that provides at least 100-150 mg elemental magnesium, other nutrients that support magnesium absorption include vitamin B6 and Vitamin C, so these added into a magnesium supplement is beneficial.
- Glucose from simple and complex carbohydrates (your body's carbohydrate reserves in your liver and muscles is called glycogen - when this is depleted the chances are great that you will feel physically drained; include intermediate carb veg in your diet such as beetroot, onion, carrot and butternut to increase your carbohydrate intake without compromosing your diet)
I hope this helps.
