I'm a third grade school teacher doing a job I usually enjoy. I am married with 3 boys;34, 15 and 13. Last year I had breast cancer and that, along with the medications I'm taking have left me with very little energy and a foggy brain. Besides needing to lose about 25-30 lbs for a Florida vacation early summer I wanted to diet to see if my energy would come back. My sister told me about the keto diet and so far I have lost 10 lbs. I don't know if its the lack of carbs, eating natural foods or lack of gluten, but since I've started this diet my energy has returned to precancer levels and The brain fog is lifting.
