Today's episode is also brought to us by David.

David makes a protein bar unlike any other.

It has 28 grams of protein, only 150 calories and zero grams of sugar.

That's right.

Twenty eight grams of protein and 75 percent of its calories come from protein.

That's 50 percent higher than the next closest protein bar.

These bars from David also taste amazing.

Right now, my favorite flavor is the new cinnamon roll flavor, but I also like the chocolate chip cookie dough flavor, and I also like the salted peanut butter flavor.

Basically, I like all the flavors.

They're all delicious.

Also, big news, David bars are now back in stock.

They were sold out for several months because they are that popular, but they are now back in stock.

By eating a David Barr, I'm able to get 28 grams of protein in the calories of a snack, which makes it very easy for me to meet my protein goals of one gram of protein per pound of body weight per day and to do so without eating excess calories.

I generally eat a David Barr most afternoons, and I always keep them with me when I'm away from home or traveling because they're incredibly convenient to get enough protein.

As I mentioned, they're incredibly delicious.

And given that 28 grams of protein, they're pretty filling for just 150 calories.

So they're great between meals as well.
