JB and Others: Appetite For Construction

Sunday,while doing my weekly diet and workout “fine tuning”,I re-read “Massive Eating” and “Appetite For Construction”. It appeared to me that Massive Eating/Nutrient Partitionong/Massive Eating with caloric deficit and increased cardio is an excellent regimen for not only weight gain BUT ALSO WEIGHT LOSS! Am I missing something? Is the reason for using things like the Fat Fast and T-Dawg (as opposed to Massive Eating with additional cardio and caloric deficit) because weight loss is more RAPID, simply a matter of choice or a little of both? It seems like Massive Eating and it’s derivations can be utilized irregardless as to our goals (ie weight loss OR weight gain). Again, am I off in my thinking?
