Hey RGourty, I just visited the Amerishape site...yes, sounds a bit too promising, but you know...I've seen worse! There are a few things that I wanted to point out to you, but I think that overall it's not as bad as you think. After all, it's a gym membership...and you can learn to like the gym!
First of all, there's no magic food combo that promotes a faster metabolism and faster fat burn. The only thing that does that is exercise. Now we're not talking crash-and-burn exercise. We're talking something that gets your heart rate up a bit but doesn't leave you sweating in a heap on the floor. An hour's brisk walk will do it. One hour a day...you can do that and you don't even need a gym. A gym comes in handy if you want to use machines like the elliptical or the treadmill, and free weight work is great for developing toning and shaping as your weight comes off.
I completely disagree with their advice to use butter and fat in your cooking. Mono and Polyunsaturated fats are what you want...fish, walnuts, pecans, almonds, flax, soybean oil, sunflower oil, safflower oil, avocados, cashews, peanuts, pecans, natural peanut butter, olives and olive oil - almost all plant-based fats. All can be eaten in moderation.
I also am leary of any site that says it's ok to eat beef and meats with skin on. Again, lots of unhealthy fats there. You want the lean proteins...chicken with no skin (white meat), turkey, and fish (salmon and albacore tuna are great).
If you have a library close by, pop in and pick up one of Dr. Dean Ornish's books...I've had the best luck, and the best health, living by his eating guidelines. Simple, medically-sound, and so easy.
You haven't been totally ripped off, so please do NOT allow your feelings of dissatisfaction to derail your efforts. Make it work...go to the gym, do the exercises, and keep on chugging. But in the mean time, really read up on nutrition and lifestyle changes.
And 9 lbs in 4 weeks...that's awesome! You should be feeling very proud of yourself.
