For the past 12 weeks, the first thing I do when I wake up is roll over, grab my $349 carb vape, head to the couch, and begin my morning measurement. I suck in a deep breath through this thing for four seconds, hold my breath for 10 seconds, and then breathe out for six seconds. A few seconds later, the Lumen app on my phone tells me whether I’m burning fat, carbs, or a mix of both. Once that’s done, it then spits out a customized plan for what I should eat that day.
In the crudest…
