Low carb diets are tough. One point often missed is to take a swig of olive oil to combat hunger and cravings for sugar. The good fat will help keep away that keto sinking feeling too. I hope you supplemented with calcium as well to help balance your ph. Acidity can run high with such diets. Dr Atkins is where I learned these factors some 25 years ago. Also, supplementation with minerals like zinc and magnesium can be important. I do.
