Building Muscle on Keto: An Interview with Luis Villaseñor of Ketogains
You can build muscle mass on a ketogenic diet: Luis Villaseñor’s results speak for themselves.

The ketogenic diet can produce some amazing results. In my previous article about getting started on the ketogenic diet, I described how ketosis can not only help you burn fat faster than any other diet, but that it can also lengthen your lifespan, improve your productivity, and even reduce your risk of certain forms of cancer.
However, one thing the ketogenic diet is not known for is its ability to put on a lot of muscle mass. In fact, it’s widely assumed to be a terrible diet for that purpose. Standard bodybuilding dogma holds that low-carb diets are ideal for fat loss, while high-carb diets are preferred for bulking up.
Luis Villaseñor begs to differ. A coach and personal trainer who has studied and followed ketogenic diets for years, he finds that the ketogenic diet is in many ways ideally suited for building muscle without gaining fat. And he has the results to back it up.
Passionate about bodybuilding due to a personal interest in improving his own physique and learning the “whys and how’s”, Luis has studied nutrition and practiced strength training since he was 17 years old. Luis has been practicing a low carb/ketogenic diet approach since 2001. He is the founder of Ketogains, and is regarded as one of the most experienced people in the fitness industry when it comes to low-carb dieting for body recomposition and strength training.
I sat down with Luis to ask him how he and his clients are able to build muscle on the ketogenic diet while staying lean and toned year-round. His advice may completely change the way you view low-carb diets.
