Life changing information and guidance.
Grant taught both me and my husband about the importance of meat in our diets, where we were making mistakes, and how to get the most out of life by eating the way we were always meant to. We found Grant's store through some friends, initially to buy meat, but we left with information no one had ever told us before. Grant had lost over 100 pounds by the time we met him, fixed his diabetes and foot problems, he also said a lot of his pain was gone, this is what made my husband curious? Brendon was diagnosed with high blood pressure, told to cut out red meat and salt, was 100 pounds over weight, and retirement didn't look fun so he started to visit Grants store more often. We lost a combined 80 pounds, Brendon isn't on his meds anymore and we have a new lease on life, all thanks to this scary man and his love of meat. :) Grant is very passionate about what he does, he even gave my husband his personal number if he had questions. A few months ago he gave us access to a program called Carnivore Battle Codex, funny name, but my husband plays on it all the time, it saved him guessing what he could eat at the Christmas parties! I highly recommend Grant's store/skool to people, he honestly wants to help people, and is a very genuine person, intimidating at first until he speaks and we are so happy to have him in our lives.

Supportive, Science-Based, and Actually Sustainable
I joined this group because I wanted a realistic, science-based approach to fitness and health without the noise, pressure, or gimmicks. What I’ve appreciated most is the tone of the community — supportive, encouraging, and grounded in real life. There’s accountability without judgment and education without overwhelm. This group meets you where you are, whether you’re consistent or coming back after a break. The conversations feel genuine, the guidance is practical, and it’s clear that sustainability and long-term health matter more than quick fixes. I’ve gained clarity, motivation, and a better mindset around progress, and I would absolutely recommend this community to anyone looking for a balanced, evidence-based approach to getting stronger and healthier — mentally and physically.
