Feeling hungry is perfectly normal and especially if you are living a healthy lifestyle that includes intense exercise. I had gastric bypass in Oct of 2013. My highest weight was 368 pounds and i was wearing a size 48 jean and 4x shirt. Today 9 months later I am 195 pounds and my jean size is 30-32. My shirt size is medium. I have dedicated myself to a healthy life style that includes intense workouts including both weight lifting and cardio. Feeling hungry is perfectly normal, the trick is to teach yourself to choose the right food to feed that hunger. Eat smaller portions more frequently every two or three hours and make sure that protein is your main food source. Limit your sugar intake. A diet with high sugar intake is a diet with high calorie intake. Keep up the good work!!
