Okay, let me start off by congratulating you on wanting to improve your fitness and joining a gym...KUDOS girl.....I'm in my 40's and wish I worked out like I do now in my 20's..I'd be smoking...but better to have jumped on the gym rat wagon now than not at all..............................
Okay about the nutrition thing at the gym. I know someoen who did this and she said it was very expensive and was basically a low carb diet......not anything she couldn't have done on her own, but they gave her incentive and knowing you are going to be weighed in (like at WW) makes you accountable to someone...

Just be careful because these kind of gym programs love selling their shakes and supplements.....stuff that you don't really need or could buy cheaper at the health food store. I tell my clients to buy a protein shake , but one that is natural as possible......and you don't need a slew of supplements, start off with a good basic mulitvitamin and I recommend Omega fish oil capsules to everyone because that is something none of us is getting enough of in our diet unless we eat alot of fish like salmon.............Omega oil is good for our skin, our digestion and I truly believe it helps with weight loss.
