What should I do if I especially like McDonald's Big Mac? After eating for many years, I feel that I have never had enough. I still want to eat two at a time.

I think if you like eating, don't deliberately change it. Although unhealthy, people always have this kind of psychology. what do you want to do? So, the more you do. You can gradually reduce the frequency of eating McDonald's. Or let others bring it for you, instead of buying it yourself. Try to eat slowly, delicious food, and distract yourself.
