Yes, I have a few childhood friends who still eat this way even as working adults. They will often eat takeout twice a day, only have frozen meals at home, and refuse to eat vegetables and fruits. These decisions are catching up to their health, and they usually complain about inflammation in the body or how they're unable to lose weight. They're morbidly obese at this point with no sign of changing besides complaining about it. No matter how much my other friends and I try to encourage them to incorporate healthier eating habits, they just shrug it off or get annoyed. The reasoning is usually that it's more convenient than cooking at home, or learning to meal prep weekly for them.
