Does The Art of Frugal Hedonism hold up?
The Art of Frugal Hedonism: A Guide to Spending Less While Enjoying Everything More, by Annie Raser-Rowland and Adam Grubb (2016)
How to spend less without enjoying life less: cooking at home, wasting less, free social life and the true cost of a car.
The short answer
Not a book about living alone, but its levers are the costs a household of one controls. It rests on practice, not statistics.
The claims, checked
No claim in this book could be matched to an official record that measures the same thing, so none is given a verdict.
