When you start with compromises like that, the failure is guaranteed, there is no “attempt”.
Considering the role of food as pleasure, this fear of big changes can backfire because people are addicted to food. It’s easier to succeed if you do a revolution in your kitchen instead of half-assed tiny changes that maintain “temptations”. It’s also much more satisfying to engage in something new, an adventure, and start to make progress in it (to accomplish things); the big change is its own reward, which helps to keep it going because you feel more agency, more capability.
At least google “food addiction”.
