NIXES NAP ATTACKS: A protein-packed lunch

Every day just after lunch, your body’s energy engines (mitochondria) slow the conversion of calories into adenosine triphosphate (ATP), your main form of energy. The result? Afternoon sleepy spells. But you can cut post-lunch draggies by as much as 67 percent by adding 3 oz. of protein (like tuna, chicken, cheese or eggs) to your midday meal, say Canadian scientists. That’s because protein revs the mitochondrial genes that produce ATP, preventing afternoon energy lulls so you stay invigorated and clearheaded.
