Reggie -- another note on the walking, I agree with Janine -- the ankle weights aren't the best idea because they are hard on the joints. Just using your body weight for now should be enough.

For more of a challenge once you build up, you can also walk where there are hills, going up hill will definitely be more challenging than just walking but easy on your brain If you have access to a treadmill, you could also do intervals or hill programs on that as well.

If you can get the Atkins book that would be great, otherwise you can use their website but please beware of what we call all their 'frankenfoods' -- meaning all the low-carb foods like low-carb bread, pasta, bars, etc....it is best to stay away from them and do the diet as the good Dr. A planned it -- mostly fresh whole low-carb (and high-fat) foods.
