From the foods you describe I'm guessing you are used to eating quite a large amount of sugar. You don't mention, for example, craving steak. (Mmmm....steak :) If "nutritional replacements aren't hitting the spot" it might just be that you're ingesting fewer calories and are hence hungry. Junk food tends to be very energy dense so you have to eat a larger volume to maintain the same amount of energy coming in. One way to blunt sugar cravings is to exercise. Particularly if you're a lard arse your insulin response can go out of wack. Exercising depletes muscle glycogen which can help bring things back to normal. You can find out a whole lot more here: http://www.bodyrecomposition.com/fat-loss/training-the-obese-beginner.html http://www.bodyrecomposition.com/fat-loss/training-the-obese... Another way to blunt sugar cravings is to fast. You'll find various people promoting "intermittent fasting". Basically, don't eat for about 12 hours. Fairly simple to say; may not be simple to do. Also, make sure you're eating plenty of protein and fat. Don't just replace one pile of carbohydrates with another (e.g. nachos with bread). If you do this you'll stay on the sugar treadmill. I hope that is useful.
