She worked out. She was miserable, hungry and tired. And, she was overweight. College brought some short term success, but she gained the weight back plus some, which ushered her into the over 200 lbs club… where she remained a member for the next 2 decades.  And then she found Keto. Go here to read her story:  https://www.theketonist.com/about

Robert Sikes

From a measly 115 pounds to a miserable 230 pounds to a ketogenic professional bodybuilder, Robert has blazed his own trail.

Robert was not dealt a good hand with regards to becoming an elite bodybuilder.  He was skinny as a rail and had no gym experience whatsoever. His first bench was an ice chest and his first weight set was pieces of loose steel his father had laying around the shop.  He didn’t have a clue about nutrition or training but he was hungry to learn.

He started following conventional wisdom in the bodybuilding community that suggested he eat TONS of calories (mostly from crap carbs) to gain muscle.  So…he did. He ate 6,000 calories a day and went from skinny to fat with the hopes of someday competing.

He continued to follow conventional wisdom when he prepped for his first bodybuilding competition, this was, a disaster.  He won the show but at quite a cost. He lost 70 pounds in three months, nearly starved himself to death, lost a ton of hard earned muscle, and developed extreme eating disorders.

There had to be a better way….Then, Robert discovered the keto diet.  For the past 4 years he has maintained a strict ketogenic lifestyle year round.  He stays keto-adapted during his offseason, throughout his contest prep, for peak week, and post show.  He has since won his pro-card, all while following the ketogenic diet. This new way of life has allowed him to 10X his performance physically AND mentally!

Robert created the brand “Keto Savage” to share the wisdom of the ketogenic diet.  It embodies the legacy he is trying to leave: “Believe in yourself, dig deep in your passion, and put in the work.  You can become extraordinary”
