No, neither shooting nor negativity was present in my response.
Addiction and cravings have physiological and behavioral components. Understanding each facet of "addiction to carbs" clears things up.
Physical cravings for carbs in an insulin-resistant metabolism is not true addiction; it is starvation. In other words, the body is not converting carbohydrate foods to available energy. Rather, it is storing carbs as body fat. Excess protein intake will also be converted to stored body fat. Limiting carbs and proteins produces a short-term heightened starvation, but this is not the same withdrawal as true addiction. It would make sense to support the conversion with something like acetyl-L carnitine, if one wanted to support the process of burning fat for energy. Endorphins are not involved in the process.
Behavioral addiction may also be present. There are many ways to overcome behavioral addiction, such as meditation, support from others, CBT, desensitization therapy, hypnosis, etc. (I'm not recommending any particular one of these, I'm just sayin'.)
Research references are abundant. Check out the bibliography of books by Taubes (or even Richard Atkins) for more references than you could possibly need.
