1. From your link "We conclude that ethanol was a preferred fuel preventing fat, and to lesser degrees, CHO and protein, from being oxidized." So for the few hours that alcohol is in your system, it is the preferred substance for oxidation. It's quite a leap to take that to development of a beer belly.
From mine, "Alcohol contains calories, but drinking alcohol doesn't lead to weight gain, according to extensive medical research, and some studies report a small reduction in weight for women who drink" This is about as clear as you can get that alcohol doesn't lead to weight gain. Care to directly address this?
2. That's a false dichotomy, You can eat fish and drink wine, too.
Also, you seem to be shifting goal posts. First you write that alcohol can't be considered "perfectly healthy", and now you write that it is premature to be suggest that it can be considered "perfectly healthy" and will lengthen your life.
Why does something need to extend your life to be perfectly healthy?
