People are fat and addicted because they seek peace and fulfillment in the form of external, objective experience. When the next cheeseburger or next drink is consumed, the search temporarily ends, and this fragile form of peace and fulfillment is attained... for a while. After that while, the peace that was momentarily revealed is once again veiled by tension and dissatisfaction. Since the external, objective experience was assumed to be the source of the peace, it is sought -- and in this case, consumed -- again. On and on, until you're hungover every morning and weigh 317 pounds.
Any diet in which you run a caloric deficit will be effective in losing weight. There's probably other science to it I don't understand, but that does seem to be the one reliable way to achieve results. However, if the cycle of searching for external, objective experience to attain peace and fulfillment is not broken, every diet, no matter how effective, has the potential for (and indeed, likelihood of) being broken, or later yo-yoing.
It is for this reason that the third element of my approach -- meditation -- is the most vital. Through this practice, we find an infinite source of peace and fulfillment that is available within, at all times. Once this pool of unlimited peace and fulfillment is found, the urge to seek that peace and fulfillment through external means dissipates. The diet itself becomes a peaceful journey, the goal a peaceful destination, and the fraudulent promise of the mind -- that what you seek lies outside yourself in the realm of external, object experience; the next flavor, the next buzz -- is exposed as the destructive lie it has always been.
To answer your question more directly: I wouldn't worry about it.
