I think its the missing of the juicy meats/sauces. I hack Huel (x4 Huel a day + 3 meals to gain weight) but dont have that legendary cheat day (yet! Famous last words).
I no longer crave sweets or crisps (or snacks in general), but I still occasionally crave juicy/fatty meats or barbequed food (with sauce). I do still hammer the meat but its mostly KFC chicken or pulled pork, with all the nasty sauces that I occasionally crave.
My wife and I used to love the pepperoni pizza and hot dogs. For ethical, ecological, practical, aesthetic and health reasons we decided to switch to vegetarianism. After a short period (maybe a year) of adaptation we have never looked back. It has been almost a decade now. Cravings go away
That’s very true! When I went vegan - about twenty years ago - I remember worrying that I would be craving cheese for the rest of my life. Even my unhealthy cravings these days (see above) aren’t that bad anymore. And a craving never lasts as long as you fear.
