Its a little bit of willpower, but its more a change of mindset and lifestyle. I do go thru phases where I can't look at another chicken breast & Ben & Jerry seem to be my best friends, but I also swing the other way and have no desire to even look at sugar. Granted my lifestyle w BB competition has moved me to the extremes of dieting as well.
I would suggest that you start by taking a look at where you are now & what tweaks it takes to move towards a more productive lifestyle. Here I mean that there is a biochemical reason why we crave sweets, i.e. 'comfort food' when we get depressed or whatever. Food & mood are tightly related. But also if junk food is a regular part of your diet, the the craving is already established -- anyone who has moved away from the junk food & cleaned up their diet will tell you that after a while you don't even want your allowed cheat meal because it makes you feel like shit. In other words, if your diet includes a certain degree of chocolate, your body has learned to accommodate that and actually sort of expects it. I love chocolate. I love sugar. I used to be able to eat ice cream by the 1/2 gal in one sitting. Now, I've done several rounds of competition diet over the last few yrs - I occassioanally like chocolate but right now it gives me a sick sugar buzz that actually makes me feel sick and panicky for at least 3 hrs. Ice cream - forget it - I can't digest lactose anymore and that makes me feel bloated and backed up for 2 days -- so I actually start feelinig sick to my stomach if I look at ice cream. Basicaly I've removed these things from my diet and my body has responded by running more efficiently metabolizing clean food. Simple sugars, heavy fats & processed foods absolutely destroy me now because my body doesn't normally process these anymore.
I hope that illustrates the route away from teh sugar cravings. It is a time-dependent process to "train" your body to run more efficiently. It can accommodate almost any change in eating behavior - for the worse or for the better - that's the cool thing about how the body works -- it adjusts to accommodate a trend - for ex, if you take the apparent route towards 'losing weight' that so many people do --- eat less - like drop your total calorie intake below say 900 cals. Sure, you will start to lose weight because your body neeeds to run on somethign - and once it burns thru the little bit of food you consume, it will start to eat thru your bodyfat AND your muscle mass. That's how you get that "skinny fat" look. But your metabolism will also respond by recognizing that the limited cal intake isn't just a one-day thing that it can accommmodate but rather this is how we are living now --> to your metabolism and its survival mechanisms, this now looks like you are livinig in a drought scenario and it will slow down the burn rate to preserve as much energy (bodyfat) as ti can - that's why you see people on these starvation diets who then start to complain about how they can't lose anymore weight -- its all slowing down.
If you disconnect your goal of "want abs" from the method of "change lifestyle" and tie it only to "i crave sweets and can't stop eating them, I must be a complete failure" -- you are basically saying "i'm a victim of myself". That doens't help anything. If you can step back from that way of thinking and allow that that you can actually make changes so you aren't a victim and you can't even keep yourself from eating shit food. Here's a couple thoughts :
-- takes about 3 weeks to change a habit - can you give yourself 3 weeks to try and make a couple changes in your diet and not freak out and feel completely helpless if you have the urge to eat some shit food and then feel bad about yourself afterwards?
- can you take the time to post up what is your typical day's meal plan? It helps to look at what you are eating - because your cravings may be a response to something that you are eating now or even if you aren't eating enough and your body says "FEED ME MORE" and you interpret it as "i need chocolate".
- also keep a "food diary" -- along w/ writing down what you eat & when youe eat it, note how you FEEL when you eat -- i.e. are you depressed when you go for the chocolate? Are you bored? Are you stressed? Is there some state of mind that your behavior sends you to respond to it by eating chocolate? If you can identify that, then you are one step ahead of understanding why you go for the junk food. Then you can maybe learn other ways to deal w/ the state of mind - ie. if you are stressed - go for a run, hit the gym, eat fruit instead - somethign other than your simplest, easiest response of "eat chocolate". LIke I said -there is a direct relationship between mood and comfort food -- it makes you feel better immediatley, but the consequences -- the increase in bodyfat, the post sugar-rush crash, etc. are all not worth those first few minutues of "relief".
Basically I'm sayign take a look at the big picture - your body doent' chcange in response to changing just one item in your life -- i.e. these protein shakes or whatever. There are lots of things that are tied together that may promote your "need" for chocolate. Identify them, make a coupel small changes at a time, keep those change in place for 2-3 weeks and you will find that eating the junk food simply doesn't "feel" as rewarding as it apparently does now and you eventually move away form it, feel better, and generally things head where you want.
Hope that helps some -- you need to look just a little deeper than "I have no will power, therefore I will be a fat fuck the rest of my life".. That's attitude is completely self-defeatiing and absolutely not the way it has to be. And it also doens't have to be a painful transition out of the chocolate dependence - just takes a little thought, effort and give it a few weeks of HONEST effort to see the results. I mean what happens if you eat the chocolate? You don't die. You just pay a little more attention next time - get it all out of your house, away from you, replace w/ some better snacks, stay busy and keep your eye on where you WANT TO BE vs where you are. If you don't eat the chocolate, then will you feel like you are cheating yourself out of something? So what? Don't focus on the damn chocolate. Get out of your head and just make it a non -issue.
In the meantime -- I'm sure you are looking for some magic pill or somethign that will help w/ your chocolate craving --- they dont' really exist -- but if you want to try an appetite suppressant --- VPX Dietex has worked for me for competition diet - it is Hoodia-based and doens't have any other sides other than it just kills your appetite. But note it doens't work for everyone - works great for me, others don't notice a difference.
But if you can start by posting up your daily meal plan, use a food counts program like www. fitday.com to see what you are REALLY eating right now. There could be a couple easy tweaks right in there that you can do to change everything very easily.
