The part that says metabolism changes with eating habits, which that study doesn't say. It does not make sense to me how eating healthy will increase the amount of calories your body burns.
the process is complicated but to simplify
fructose --> high insulin response --> over acute term fructose levels decrease (high glycemic index), however insulin levels remain elevated --> chronic insulinemia
insulinemia signals to the body that you are in the fed state and this is a good opportunity to store materials for the future. simply stated insulin results in decreased lipolysis, increased triglyceride synthesis (fat storage), decreased gluconeogenesis, and increased glucose stores in the form of glycogen. your body does just this and more in response to chronically elevated insulin levels, regardless of what the actual nutrient supply is. since high fructose products have a high glycemic index, they will leave your body very quickly, but due to the sustained increase in insulin - you will still be overcompensating to store foods you ingest, even if you are eating very little quantities. this is why it is not all about calorie counting, but what foods you are eating.
2k calories of sugar = 2k calories of sprouts as far as potential energy stored in each, however to think your body reacts the same to the two options infers gross misunderstanding
if you want a source i will reference you to any biochemistry textbook written after 1991
