Bryan Johnson compares beer and hard seltzer: both have 4-6% alcohol, but beer has more calories and carbs that spike blood glucose and stop fat burning. Alcohol itself is a Group 1 carcinogen that cuts fat oxidation by 70%. If forced to choose, he'd pick seltzer for fewer carbs, but says skip both.
You're at a party. Which one is worse, beer or seltzer? Most beers have 4 to 6% alcohol. They're also higher in calories and carbs compared to other alcoholic drinks. Those added carbs increase both your blood glucose and insulin load, which temporarily pauses your body's ability to burn fat. Seltzers also have between 4 and 6% alcohol. Despite having more ingredients, they have fewer carbs and calories, which means slightly less stress on your metabolism. Both of these drinks are terrible. Alcohol is a Group one carcinogen, even one drink a day increases the risk of all kinds of cancers. Your body sees alcohol as a toxin. After you drink it, fat burning drops by 70% just so that it can focus on clearing the alcohol from your system. Now, if I had to choose between beer or a seltzer, I would choose a six-pack of abs. Bryan, the people want to know. Okay, I would choose a seltzer because beer adds unnecessary carbs and calories. Seltzer removes some of that metabolic drag. The best answer is neither.
