Hi, Cajun!
With your name, I'm guessing you come from the same neck of the woods as I do (NOLA born and raised here). I'm convinced that those of us down here on the South Coast have a tougher time with gaining weight just because everything tastes so goo-o-o-o-o-od!
Good for you for getting a gym membership--use it and be proud! Not only will you feel terrific about your improving health, but you'll be an example for others when they see what you can accomplish.
What's your plan for your food, if you have one? I'm doing calorie counting specifically because I feel I might die if I never got to eat jambalaya again because of its carb content.
