i wouldnt freak about ur carb intake its not really a lot. as far as mark goes i think hes met his goals and only needs to maintain himself. i believe he said he doesnt workout like he used to. so his requirements to maintain are dif than most. i go thru 1200g of carbs in one day cause im doing an extensive program im not saying u should do this but just showing u dont need to be in keto to achieve goals of muscle gain.
