I have looked into the KetoGains website and FB group, and there is some good stuff on there. The Dom D'Augustino, Rogan, Ferris, Attia, etc stuff I have been listening to is much more focused around overall health, it's effect on cancer, diabetes, dementia, etc. They all kind of touch on fat loss as a side effect it also has without really getting into the weight loss how to stuff. The Ketogains ppl mostly hit on how to lose weight with it and how to build muscle while on it. It is much more applicable of information, imo.
Also, they have some basic workout info, have their own macro calc, do custom nutrition plans, and custom workouts. The latter two are pay items.
Interesting stuff and a very active FB group if you have questions. Would recommend if you are a Ketocat.
