Starting over and doing it right...

Since last Summer, I dropped my calories to about 1200 to 1300 and upped my progress in the gym. I got stronger but I heavier in other ways too. This method worked in my 20's and 30's but at 41, things change. I was totally stumped until I saw a doctor who specialized in health and wellness using nutrition. He said I was pretty much in starvation mode and was comsuming the calories of a 12 year old. I came here to get a handle on what I eat. I've found eating good food and getting the calories I NEED for proper living actually involves alot of food, which isn't a bad thing.
