One of the often-used catch-phrases, platitudes, sayings, or whatever you want to call it is that "nothing tastes as good as thin feels." I'll be right up front with my opinion that I don't believe this is true for overweight people, and the the statement isn't very helpful for people who are obese in particular.
The first issue I have with this statement is that it's like telling a child that he should study hard instead of playing so that he can get a good job and be happier as an adult. Embracing and fully internalizing the idea that a state you may (or may not) achieve in the distant future is going to be so much better than immediate gratification is not easy. Many very overweight people see "thin" as something which they are incapable, perhaps genetically, of ever being. The best many of us hope for is to be "less fat."
Second, many people with weight problems haven't been thin for a very long time, if ever. In my case, and the case of many obese people, I haven't been thin since childhood and it wasn't a state I fully appreciated at that time. I have no idea what "thin" feels like. Like the child who is told to sacrifice now for the future, I can't even begin to relate to the reward that I'm striving for. I can't assess the value of feeling thin since I've never felt it.
Third, it's simply impractical to weigh the value of being thin to a sensory delight. Being thin creates abstract rewards and food is a concrete one. It's comparing apples and oranges. One brings about esteem and image benefits and the other is setting off endorphins in your brain. One directly stimulates your pleasure centers and the other is indirect.
Finally, I don't personally believe that "being thin" is necessarily going to feel great. I think that the real issue is not suffering the bad aspects of being fat, not good aspects of being thin. Essentially, you're avoiding pain, not gaining pleasure.
I think the decision to lose weight among many people comes as a result of thoroughly being fed up with the suffering they endure from being fat, and one of the reasons they regain is that absence of psychological and physiological pain is a less potent motivator than the immediate pleasure and comfort one gets from food.
My point in bringing this up is not to discourage weight loss or to say that it isn't worth the sacrifice of the pleasure of food. It's more a recognition of the fact that, unless you lose weight and are attractive and young, the rewards for being thin are not a potent motivator. The motivation is no longer suffering the misery of being fat.
