I think I'm addicted to McDonald's.
How did you become addicted to McDonald's?
I think it's because the food is tasty.
McDonald's knows how to engineer food that tastes irresistible, but lack of nutritional value doesn't justify the calories and sugar. You should take a break and explore how to make healthy food delicious and recalibrate your relationship to McDonald's.
I'm not facing any negative consequences from eating this food, so it doesn't matter.
You might not be seeing the consequences now, but it will catch up to you in the future if you only eat junk food. If you like McDonald's that's fine, but you should save it as a treat instead of eating it every day.
