This is just short-term vs long-term gratification and competing desires. That's not intrinsic, except insofar as newly formed habits are compulsive.

Choice and opportunity-cost is all "self-limiting", the only difference is perspective. It's better to have an additive-mindset, i.e. replace a habit with another that provides value rather than merely focusing on restricting something. This works for everything, including diet. In the words of Allan Carr, if you view your actions as sacrifice, you won't succeed.
