I think the standard answer is that some traditional cultures rely quite heavily on carbs with very low incidence of obesity. Some even eat substantial amounts of sugar (e.g. as honey).
Herman Pontzer did such a study for the Hadza who eat a lot of honey.
He came to conclusions like “To Pontzer, this means that the human body seems to adjust to physical activity by saving calories on other physiological processes to keep total energy expenditure in check.”
Has the hypothesis
excess sugar/carbs → metabolic syndrome → constant hunger and overeating → weight gain
been disproved?

The key here would be an exact quantification: how much carbs do these cultures consume in relation to the amount of physical activity.
