Just one more question for tonight.I moved to a higher altitude about a year ago and started immediately losing weight.My wife to has lost a lot of weight..I went to the doctor and got all clear and I told them of my weight loss..They said good its better for your blood pressure and your heart etc..OK its better.. but im thinner than I have ever been in my life.. I eat sweets and more than I have in the past months but can't seem to really gain weight. Im not that active yet I keep maintaining a low body weight which i checked and im on the lower end of acceptable and well can't seem to pick up any weight.I was told when we moved here that the metabolism is three times faster even when you are sleeping and to tell you the truth I look around and very seldom see anyone that is really what i call overweight.Most of the people here are on the little side..I look older because my skin is just losing its vitality..We live in what they call a high plains dessert.. Could this just be something that is normal here or could there be something wrong with me? I asked the doctor and told them that both myself and my wife has lost a lot of weight..they said good and my nurse friend that comes by says that older people that have the metabolism in the genetics that it kicks in and they get small.. she doesnt seem to think its a problem..and that its healthy and said if it worries me to eat more but I eat a lot. .and don't gain.. What is the problem..could this be normal and will I always be this small or could there be something else wrong with me? Please advise..?
