Carbs vs Protein During Exercise: Hormones, Cortisol, and Insulin. Registered dietitian nutritionist Leyla Muedin discusses an emailed study request about a 2013 Iranian paper comparing carbohydrate vs protein drinks consumed during resistance exercise in 20 fasted young men. The study found cortisol rose much more in the protein group while insulin rose more in the carbohydrate group, with no significant differences in growth hormone, testosterone, or IGF-1, and it concluded carbohydrates created a “better hormonal environment.” Leyla challenges this interpretation, arguing cortisol’s rise is a normal and useful exercise stress response for muscle breakdown and subsequent repair, while carbohydrate-driven insulin spikes...

There's a crucial molecule in your body that helps control everything. Your circulation, your energy, your stamina, your heart, even your sharpness of mind. It's called nitric oxide. But after age 40, your body makes less and less of it. Less blood flow, less stamina, less of you. But now there's N101, the nitric oxide lozenge developed by Dr. Nathan Bryan.

0:22

The world's leading nitric oxide researcher backed by Nobel Prize-winning science. ANNO 101 is designed to naturally restore your body's nitric oxide levels. Just do what I do and let one dissolve in your mouth twice a day. I especially make sure to take it before workouts.

0:38

ANNO 101 goes to work in minutes, releasing nitric oxide directly into your bloodstream, supporting healthy circulation, boosting oxygen delivery to your muscles and brain, helping you feel the way you're supposed to feel. More energy, better blood flow, sharper focus.

That was the opening. The rest of the episode (20 min) is in the player: every word clickable, with translation, saved words and flashcards.
