A meta-analysis reports that short-term trials of alternative sweeteners did not show harm but some observational studies suggest possible increased total energy intake in habitual users. Which conclusion is the most balanced and evidence-based?

Since short-term trials show no harm, all observational findings suggesting increased intake are irrelevant and can be ignored when forming dietary guidance for any individual.

Limited use of alternative sweeteners is not conclusively harmful and they can be part of a healthful diet, but unresolved questions remain about appetite regulation and compensatory eating that warrant cautious interpretation and further research.

Alternative sweeteners are definitively harmful and will always lead to weight gain because observational data alone provide conclusive evidence of causation between sweetener use and higher total energy intake.

Alternative sweeteners have been proven to cause dramatic metabolic changes in all populations and should be banned from all food products to protect public health.
