What you say is only partially true. One can still consume whatever is desired, but in much smaller quantities than desired. For instance, I have been obese for many years. Then I have succeeded to lose (after several failed attempts) more than one third of my initial body weight. After that, I have changed completely my eating habits, otherwise I would have reverted immediately to my old weight. Now I have been controlling my weight accurately for more than a decade. I am still eating cakes, but only cakes that I cook myself from known ingredients, and only twice per week (Sunday and Wednesday) and in a quantity that keeps the daily intake of sugar for those days no greater than 40 to 50 grams. With these exceptions, I do not eat any kind of food with added sugar, so now if I happen to taste some of the industrially-produced sweet food that I liked before, it feels much too sweet, while some vegetables with low sugar content, like onions or red bell peppers, feel quite sweet. However many months have been needed until overcoming the addiction to sugar.
