Even for the Guardian, the article seems short and simplistic.

Doing a quick web search - there are quite a few copycat stories. Never any mention of how his car got stuck, nor whether he'd tried to reach safety or call for help, nor a missing person police report, nor any search for him, nor ...

Not saying I think highly of the Daily Mail - https://www.dailymail.co.uk/news/article-2103339/Swedish-man... - but their backstory (the man being deeply in debt, depressed, estranged from his family, and recently broken up with his girlfriend) would seem to answer a lot of questions.

The Danish Wikipedia article seems to be reasonably thorough and sourced: https://da.wikipedia.org/wiki/Peter_Skyllberg

This was a rural area, but he was a few hundred meters from a big road. Surely he could have just exited the car and walked there.

With a severe caloric deficit for 4-6 days, intense hunger mostly goes away.

If someone were significantly overweight, they might be able to survive 2-4 months without significant caloric intake.

The problem is numerous risks: neurological, cardiovascular, gall stones, osteoporosis, kidney and liver concerns. These are better than dying, sure, but it would be better to avoid tempting fate and permanent injury in the first place.
