Honestly, what nonsense. More like, the reason why the French obesity rate is 17%, compared to 23% in the UK, and 34% in the US. These are some of the factors which maintain health - to do exercise as part of your daily routine, and to be able to buy good quality food and cook it yourself. Then, to have enough time to spend with friends and family, and to have access when necessary to good quality healthcare.

It is valuable to have a culture which makes these fundamental requirements accessible and normal. There is no point in squeezing out every short term marginal improvement in economic efficiency regardless of the health of the people who are supposed to be reaping the economic rewards.
