It took consistency and discipline for me to reach my health, weight loss and fitness goals by adopting a ketogenic nutrition program coupled with caloric restriction through time-restricted fasting.  After my severe sciatic episode and spinal surgery, I had  gained 40 lbs. It took 8 years of yoyo dieting and exercising to lose 10 lbs, a year of semi-low carbohydrate eating to lose the next 10 lbs, and less than a year of  ketogenic nutrition and intermittent fasting to drop the last 20 lbs of fat.
