I reckon the obesity epidemic is the result of too much sugar, too many trans fats and too much food generally.

People seem to eat constantly, not just at mealtimes.
We used in the fifties to have just three distinct meals - breakfast, dinner and tea. (breakfast was a decent meal of cereal or porridge, egg and toast or a fried selection, dinner was what is now called 'lunch', and tea was a light meal such as scrambled eggs or cheese-on-toast (Welsh rarebit). Nothing else at any other time.

Very few folk were obese.

We're always seeing people munching away in the street, and they seem to keep at it while watching TV in the evenings as well (snacks like chocolate, crisps and those ghastly doughnuts)
