Welcome Vrai. Good for you for making the choice to be healthier this year. Just think of all you can accomplish in the next 365 days!
I may be the anomoly here but I never bought a cookbook or a "diet" book on whole food eating. There is so much available online and I've been able to adapt a lot of recipes to a more whole foods way of eating. The Sonoma and Medieterranean are a bit higher up in the forum has lots of whole foods recipes to use. I personally went this route for my health. After I dropped 80+ pounds, my choles. had dropped 50 points and my glucose whcih was normal before has dropped to optimal so the proof is in the blood tests for me!
Eating the whole foods way is fabulous for health, but even too much of a good thing can make us fat! If weight loss is one of your goals you'll want to also look into a portion control mechanism. For some people, that is doing weight watchers and counting points, for others it is calorie counting, other might want to try the sonoma plate division method. All of these methods can go hand in hand with whole foods way of eating. You have to pick what is right for you. me I calorie count and eat whole foods way. A great a free way to track calories online is something called fitday
www.fitday.com. I personally purchased calorie counting software called dietpower that resides on my computer so I don't have to be online to use it. Some people use the old pen and paper method. You just need to find what works for you best.
Don't forget exercise. If you havent worked out in a while, you'll want to start with shorter workouts probably, but again you need to go by how you feel. I started out with 15 minutes of very easy walking in place and now am doing tough 70-90 minute step aerobics sessions. You will improve if you keep at it. Consitency is key.
I get most of my recipes from allrecipies.com and just adapt them to w whole foods way of eating.. leaner meats, sub whole grains for more processed grains, scads more veggies, etc. Under my signature I also have a link to a recipe/review page I have that has lots of rvewis of recipes of tried as well as any healthier revisions! Or course not all the recipes are health but most are.
I hope someone else may come along with a book recommendation for you.
