But eating too much ice cream will contribute to obesity in a relatively clear cut way
Unless you compensate by eating less other stuff. (For an extreme example, eating 1900 calories’ worth of ice cream per day and nothing else arguably is “too much ice cream”, but won’t make you obese.)
(I don’t understand why ice cream is so often considered a stereotypical example of high-calorie food. One cone of ice cream contains less calories than a 45-gram bag of m&m’s or a half-litre bottle of Coca Cola, and it will satiate me much more than either of those. Of course, eating too much ice cream can contribute to obesity, in the sense that eating too much bread, or too much of anything else, can.)
