I’ve got to agree with Suck.
I’ve done the very low carb/high fat diet before, and while it’s fast and very effective for losing fat, I personally did not gain much new lean tissue while on it.
Adding the consumption of fast-acting carbs during my workouts corrected that.
I suspect that a lot of people who try the “anabolic diet” mistakenly believe they’re building new muscle because, while shedding fat, the muscle they already have becomes more visible and defined.
Many of us have heard the stories of the 60’s warriors living on the heavy cream & raw egg shakes, and the success they enjoyed.
Don’t forget, though: a lot of those guys were - at the very least - dabbling with pharmaceutical grade anabolics that were yet in their infancy.
Guys like Freddie Ortiz & Larry Scott still kayfabe it, but others like Bill March are an open-book when it comes to John Ziegler, Dianabol use, dosages, and who was using.
That’s reality.
Even Charles Poliquin, who advocates fats over carbs, insists that high-glycemic carbs are crucial following intense training.
And, if you’re already as lean as you want to be, most/average people should have no problem consuming a total of 200-250 g of carbs from good sources throughout the day, while maintaining their current condition.
I always encourage people to experiment and find what works best for them, but be honest in assessing the results and understand what is happening and why.
