I am 5'4 and 130lbs. I do not take enzymes. I exercise on average three days a week run/jog for 5 miles. But I eat and eat and eat a lot. I don't seem to gain weight but boy can I eat. Plus, I don't get overly stuffed that often. I will have a sandwich and chips for lunch and then a bowl of cereal to top it off. Then dinner I eat my whole plate and then clean up my kids plates. I know thats pathetic but I am a very good eater. Anyone else with this huge appetite and not gain weight?
