Both have roughly 97 calories per shot. That’s about the same as a small banana. But nobody eats one banana and then orders a second banana. With alcohol, you do.
Mixing is the real enemy. A tonic water has 20 grams of sugar. A Diet Coke has zero. So, a G&T is secretly a sugar bomb. A vodka soda is basically a sad, fizzy water. Your call.
Bizarre fact: if you drink gin with light tonic and a squeeze of lime, you’re ingesting Vitamin C. That’s like wearing a ski mask to a bank robbery and calling it a "balaclava." Technically true. Not helpful.
