I can confirm at least one part of this story with a personal anecdote:<p>As a child, I absolutely loved, craved, was addicted to Coca Cola. A liter a day, perhaps more. Coming to the US, I noticed that it tasted different because of substituting sugar with high fructose corn syrup. No problem - I switched to Mexican Coca Cola (the one in a glass bottle) - and carried on.<p>Fast forward to after grad school, I wanted to get in a better shape, without giving up sweets entirely (I definitely have a sweet tooth). So the first thing I did is to not buy coke. I could still get it if I wanted - the local 7-11 was literally across the street from my place. But it was no longer convenient - I had to get dressed and cross the street, deal with the line, the cashier, pay more for my guilty pleasure, etc. I still went, but definitely less and less frequently.<p>Fast forward a few years and coke started to taste very "heavy" to me. It had this aftertaste that I never noticed before but could no longer shake off. I found myself frequently unable to finish a bottle of coke. My cravings started getting less and less pronounced. This downward (well, upward in terms of health) slope continued and today I no longer crave Coca Cola at all, drinking it perhaps 5 times a year, if that. And even then I can't really do more than a few sips.<p>I look back on this and it honestly feels a bit surreal, knowing that my starting point was (multiple) liters per day and true joy and love for that sugary drink.<p>So progress is definitely possible as long as I took care to make the right choice the easy choice. Don't go hungry to the supermarket. Don't buy things because that makes them easily available, testing your willpower, which is inevitably finite. Make a few basic rules to follow rather than agonize over every small decision and feel guilty afterwards (just like the article said). Simple stuff like that.<p>Some things will stick, others won't, but that's okay. The key is to keep trying to get better and healthier, without losing the small pleasures in life without which, let's be honest, is this even worth it?!<p>Good luck to everyone on their personal journeys.
