If you read the papers on palatants and food processes destined for animals, they'll increase consumption by 20, 30% easily. Check out this patent for a horse nugget, for example: https://patentimages.storage.googleapis.com/63/5b/ef/5e6b6bd... So if you take that and realize there's more money in palatants for humans than in animals, that'll explain an entire obesity epidemic entirely without any other explanations.…
To be fair the best French baguettes are crunchy and soft at the same time and have only water, flour, salt, sugar? and yeast, so nothing much to be afraid of there.
If Americans had sushi and baguettes they wouldn't be slim like the French and Japanese, they'd eat sushi till they are 110% full (the Japanese aim to not stuff themselves at meals) and then carry around a bag of baguettes for in-between grazing (the French prefer set meals).
They'd also blame everything on their delicious national cuisine, rather than on themselves.
