I personally don't buy into the AWT book - he is looking to cash in on diabetes but lots of his recipes are simply 'low fat, low GI' which are good, but nothing remarkable. Actually, my problem might jsut be that he irritates me 
If you wanted to give lower carb a whirl, here's the types of things I would eat:
Brekkie - eggs in any form, bacon, ham, I often have raspberries (one of the lower carb fruits) and cream. You can also have things that are not traditionally breakfast items but there is no reason why you can't have for breakfast - I sometimes make a breakfast frittata with ham, cheese, peas, cream. This keeps well and can be eaten cold (or heated through the next day).
Lunch - soup (as long as not bulked out with potatoes or rice - lots of them are), salad with any protein like egg, cheese, fish, chicken, lots of leaves, tomatoes, cucumber etc.
Dinner - any meat or fish with lots of veggies or salad (and any creamy or tomato-ey sauce you fancy, lots of cheese). Sweet potatoes are good,but even lower carb is butternut squash which is great. I would have, for example, a nice steak with buttered green veg. Basically zero carbs and very tasty.
Today for a low carb snack I had a packet of bacon strips from M& S (the type you would throw in a salad) or you can have a hard boiled egg, cheese, some nuts (but watch out things like cashews are quite high carb - macadaemias are excellent).
I have done this for phases since being diabetic and have to say it has made the whole control issue a breeze. BUT, it is hard because many yummy things are obviously off the menu. I think a balance of doing this with teh occasional carby splurge is the best bet and easiest to maintain. I will also admit that now that I am pregnant I am craving carbs and just can't do the low -carb thing right now, so instead I am on the up and down rollercoaster!
There are LOTS of low carb cookery books on the market but a lot of it is common sense and just working around what you don't want to eat!
