40 yr old smoker, overweight and always tired

I agree with everything the above poster said, but also do you plan to do anything about the smoking? It probably has a lot to do with you tiredness too.

Start by elimating the small things that you wouldn't miss much, like for instance switching from regular drinks to diet or less calorie ones, then slowly increase your amount of activity, like on your first day of exercise you could walk 15 minutes then in the next day or two increase it to 30, and keep increasing it. And by all means go to your family Doc and get a physical to make sure you are healthy enough to start a work out program. There's an excellent website that I belong to that provides all sort of information and support and it it free to join. It might interest you. Hope this was helpful. http://www.eatbetteramerica.com/
