A 12 oz can of 5% abv is .6 fluid ounces of ethanol. That's 14 grams, or 98 calories.
A Budweiser has 145 calories, White Claw has 100, Old Chub Scottish ale has 264.
Basically I see the benefit over most craft beer, but over macros it's not that big of a difference.

I cant find an exact answer, but combining the ideas that: the metabolic pathways for ethanol take precedence over the metabolism of other food components, leading to fat conversion and storage of higher-kcal foods than would be expected if the energy for metabolism was not diverted to the alcohol; the extra energy needed to metabolize alcohol should become a net drain on energy reserves; and alcohol is almost never fully metabolized, but rather excreted as acetic acid - I think it is safe to assume that an ethanol calorie actually provides the body very little energy AND if youre not eating while you are drinking there isnt a way for the body to store the energy as fat for later.
