My diet used to be as bad as Hansel and Gretel's. A long-term keto diet neutralised the habit for a few years. But after it returned, what worked for me in changing it was to rigorously substitute plain foods for the richly processed stuff (meals and snacks) until I learned to appreciate simple tastes. For instance snacking on fruit, nuts, crackers and ryvita, buttered toast, cottage cheese and natural yoghurt. I wasn't able to shake my chocolate cravings, but over time, the pull of intensely sweet stuff died back, to the point where the sugar rush from ice cream or wedge of chocolate cake makes me feel sick enough for me to prefer to avoid them. To anyone who tries this approach, good luck.
