Every food commercial, advertisement, and packaging in the US is currently protein obsessed. I just bought 3 burritos, and the most noticeable thing on the entire package is its protein content. TV commercials about waffles are advertising that they have X amount of protein per serving. The products in my jobsite’s vending machine have protein all over every package.
Did America have a protein thing recently?
Protein takes longer to metabolize into energy than carbs, hence you don’t crash like with carbs. Starchy veggies give you carbs, low-carb veggies don’t have protein or carbs so you’ll just be extra tired.
