Neural Response to Carbohydrates, Fats & Proteins (Part III) || Fahad Ahmad & Corey Behn

Our last part of the 3-parter science-heavy series on the macronutrients and how they impact energy intake using a 2016 review paper.


Fahad Ahmad is a serial entrepreneur who enjoys delving into the science of food and nutrition. He practices Ashtanga Yoga, Weight Training, Crossfit, Calisthenics, and Plyometric type of training and has been part of the fitness and nutrition world for more than 15 years. He leads the "Modern Renaissance" lifestyle of tapping into multiple knowledge bases to solve a problem.

Corey Behn lives a multifaceted life rooted in a foundation comprised of Yoga, Science, Adventure, and Nature. He has always had a burning curiosity of existence itself, constantly seeking out truth in all corners of the universe. He enjoys the sport of rock climbing and photographing beautiful landscapes and macro scrapes alike. When night falls, the cosmos up above receives his full attention, studying all types of celestial entities. Corey’s role at Ketogeek originates from his love of creative cooking in the kitchen, continuously creating new symphonies of flavor and texture for our tastebuds.
