Its the psychological problem. Quitting smoking, for example, would be pretty easy without the addiction aspect. Likewise, considering low carb for example, losing weight is really easy when your appetite almost entirely disappears and a world full of candy bags and giant size corn syrup sodas has no similar instant gratification for low carb'ers. People who are used to neopuritan joys of dieting such as agonizing craving don't understand that the main point of low carb is not feeling hungry leads to imploded 'energy in' as you state etc. Also when I fall off the wagon for a day and eat a ton of bread or b-day cake or whatever I can't tell the difference between indigestion due to systemic shock of my digestive system vs the stereotypical "binge and fall asleep on the couch" I remember from my self and observation of others. A pizza makes me lay on the couch in a tired state like many other people I've observed, but I can eat a steak then go to the park with kids full of energy no problem.
