In this episode of the Greatist Podcast we chat with John “Roman” Romaniello, co-author of the New York Times bestseller Engineering the Alpha, now one of the best-known books on high fat diets, intermittent fasting, and hormone manipulation.

He’s also a brilliantly successful trainer and self-marketer who has amassed a substantial following on Facebook and Twitter with his self-effacing humor, tremendous geekiness (he has a Lord of the Rings quote tattooed on his chest), and frank views on sex, masculinity, and everything health and fitness. He has particular expertise in improving fat loss by naturally manipulating hormones, and advocates for “simple, but not easy” changes to lifestyle and training methods that increase testosterone, insulin sensitivity, and growth hormone. Have a listen!
