No legs cramps and digestion/ stool has been less but regular. I have yet to experience any negative side affects. I plan to introduce plants and limited carbs once the excess fat around my waist has diminished. I spent or 8 weeks working out and 6 mile eliptical HIIT training and it my waist wouldn't budge even with a diet that consisted of protein, broccoli, cauliflower and greenbeans and onions. I was using maple syrup instead of plain sugar as a sweetener for tea and coffee at the time which most likely was the problem even though it was limited.
