Sugar Drives Overeating, Not Unique Metabolic Harm, as U.S. Intake Falls 10%

Summary
Controlled-trial evidence reviewed in the analysis suggests sugar is not uniquely toxic to metabolism; its bigger risk is that sweetness makes foods more rewarding and easier to overeat.
Studies cited found liver fat and insulin-sensitivity worsened when sugary drinks supplied 10% to 25% of daily calories, but much of that harm appeared tied to excess calories rather than sugar itself.
When sugar replaced other carbohydrates, results were mixed: some trials showed worse fasting glucose or insulin, while others found little difference or even improved glycemic responses.
Sugar-sweetened beverages remain a public-health target because they add nutritionally empty calories, yet evidence that they cause unique metabolic dysfunction apart from overconsumption is still inconsistent.
U.S. sugar intake has dropped about 10% over the past quarter-century to roughly 91 grams a day, while obesity has not fallen, reinforcing the view that hyperpalatable food environments drive eating beyond hunger.
