I have been following the Keto diet for about two weeks. I have dropped about ten pounds and by testing my blood using KetoMojo it appears that I am solidly in ketosis. In the last few days I have experienced joint pain and severe tightness in the muscles down my right leg. I have heard about the "keto flu" where you body goes through a process when changing over from burning carbs to burning fat where you experience flu like symptoms. Any thoughts on that or or in the area of leg pain? I drink about ten cups of water per day and I take a magnesium supplement.
